graph LR
    A["EZ Mode"] --> B["Calibrate"]

1. Allow some time for the scanner to cycle through the focus, gain, and tracking settings. Do not move or disturb the scanner or test symbol while calibration is in progress.

2. When calibration is complete, the settings that provided the highest read rate will be selected. You will see one of the following messages: Calibration Passed, Calibration Failed, or Original Settings Were Optimal.

Note: To silence the beeper, interrupt scanning by removing or blocking the test symbol, or send a command to disable the beeper.

If calibration fails, try the following:

1. Check the read range for your particular symbol density.
2. Examine symbol quality and try a different sample symbol.
3. Slightly skew or tilt the symbol or scanner to minimize specular reflection.
4. Verify that the correct symbology is enabled.

Step 9 — Test Read Rate

Important: To receive symbol data through the 9-pin configuration port, you must enable the port with the following command: .

1. Position the symbol in front of an operational MS-890 scanner.
2. Click the Utilities button.
3. Click the Start button in the Read Rate view.

graph LR
    A["Utilities"] --> B["Decodes/sec"]
    A --> C["Percent"]
    B --> D["Start"]
    C --> E["Clear Output"]

If calibration has passed, the scanner sends data to the host computer and emits a beep (if the beeper is enabled) for each good read.

Move your symbol toward the scanner and away from the scanner until the decode rates drop off in each direction. This will give you a sense of the depth of field (inner and outer ranges) for your symbol's density and range.

Depth of field

Note: If the scanner is in the default Continuous Read mode and not in read rate or calibration routine, it will read and beep repeatedly as long as a readable symbol remains in the read range and the read cycle configuration has not changed.

RS-232/422 Host Port

Includes host port connections and host protocols.

Communications Options

You can communicate with the scanner through the following ports:

• 9-pin D-sub external connector
• Wiring box
  • 25-pin D-sub external connector

Only one port can be used at a time to receive commands.

Communications with Host through the 9-pin Host Port

For the 9-pin configuration port, set the host communications settings as follows: 57.6K baud, 8 data bits, 1 stop bits, and None parity. See Chapter 1, Quick Start, for more information on using the 9-pin port.

Note: The 9-pin configuration port settings are not changeable.

Communications with Host through the 25-pin Port

The default 25-pin host port configuration settings are as follows: 9600, 7, 1, and Even.

Making changes to these communications parameters without corresponding changes in linked device(s) can result in the loss of menu access. If this should occur, connect via the 9-pin port and reset your scanner's host parameters to match the 25-pin defaults.

Communications with Host through the Wiring Box

The settings are the same as those of the 25-pin port. See Chapter 14, Wiring Box, for details on wiring connections.

Host Port Parameters

Important: This applies only to the 25-pin port and wiring box connections (not for 9-pin port).

Note: See Communications with Host through the 9-pin Host Port on page 3-3 for 9-pin host port parameters.

Baud Rate (Host Port)

Usage: Can be used to transfer data faster or to match host port settings.

Definition: The rate at which the scanner and host transfer data back and forth.

Serial Cmd:

Default: 9600

Options: 0 = 600 1 = 1200 2 = 2400

$$ 3 = 4 8 0 0 4 = 9 6 0 0 5 = 1 9. 2 \mathrm{K} $$

$$ 6 = 3 8. 4 \mathrm{K} 7 = 5 7. 6 \mathrm{K} 8 = 1 1 5. 2 \mathrm{K} $$

Parity (Host Port)

Usage: Only changed if necessary to match host setting.

Definition: An error detection routine in which one data bit in each character is set to 1 or 0 so that the total number of 1 bits in the data field is even or odd.

Serial Cmd:

Default: Even

Options: 0 = None 1 = Even 2 = Odd

Stop Bits (Host Port)

Usage: Only changed if necessary to match host setting.

Definition: One or two bits added to the end of each character to indicate the end of the character.

Serial Cmd:

Default: One

Options: 0 = One 1 = Two

Data Bits (Host Port)

Usage: Only changed if necessary to match host setting.

Definition: Number of bits in each character.

Serial Cmd:

Default: Seven

Options: 0 = Seven 1 = Eight

Host Protocol

Usage: In general, point-to-point protocols work well in most applications. They require no address and must use RS-232 or RS-422 communications standards.

Definition: Protocols define the sequence and format in which information is transferred between the scanner and the host, or in the case of Polling Mode, between scanners and a concentrator. Important: When using Polling Mode, LRC must be Enabled and Preamble/Postamble must be Disabled.

Serial Cmd:

Default: Point-to-Point

Options: 0 = Point-to-Point
1 = Point-to-Point with RTS/CTS
2 = Point-to-Point with XON/XOFF
3 = Point-to-Point with RTS/CTS and XON/XOFF
4 = ACK/NAK
5 = Polling Mode 

Point-to-Point (Standard)

Usage: Used only with RS-232 or RS-422.

Definition: Standard Point-to-Point requires no address and sends data to the host whenever it is available, without any request or handshake from the host.

Serial Cmd:

Point-to-Point with RTS/CTS

Usage: A scanner initiates a data transfer with an RTS (request-to-send) transmission. The host, when ready, responds with a CTS (clear-to-send) and the data is transmitted. CTS and RTS signals are transmitted over two dedicated wires as defined in the RS-232 standard. Used only with RS-232.

Definition: Point-to-Point with RTS/CTS (request-to-send/clear-to-send) is a simple hardware handshaking protocol that allows a scanner to initiate data transfers to the host.

Serial Cmd:

Host Protocol

Point-to-Point with XON/XOFF

Usage: If an XOFF has been received from the host, data will not be sent to the host until the host sends an XON. During the XOFF phase, the host is free to carry on other tasks and accept data from other devices. Used only with RS-232.

Definition: This option enables the host to send the XON and XOFF command as a single byte transmission command of start (^Q) or stop (^S).

Serial Cmd:

Point-to-Point with RTS/CTS and XON/XOFF

Usage: Used only with RS-232.

Definition: This option is a combination of Point-to-Point with RTS/CTS and Point-to-Point with XON/XOFF.

Serial Cmd:

ACK/NAK

Definition: See the ACK / NAK Options command on page 3-8.

Serial Cmd:

Polling Mode

Definition: See the Polling Mode Options command on page 3-9.

Serial Cmd:

Poll Address

Serial Cmd:

Default: 1

Options: 1 to 50

1 = Poll address 0x1C, Select address 0x1D
2 = Poll address 0x1E, Select address 0x1F
...
50 = Poll address 0x7E, Select address 0x7F 

ACK / NAK Options

Definition: These parameters take effect for ACK/NAK on the main RS-232 or RS-422 ports (not on the Auxiliary Port), and are completely independent of the Polling Mode Options .

The scanner always follows the protocol in both directions (to and from the host). There is no option to disable it from either direction.

Serial Cmd:

RES-NAK Defaults

RES: (Reset) 0x00 (disabled)

REQ: (Request) 0x00 (disabled)

STX: (Start of Text) 0x00 (disabled)

ETX: (End of Text) 0x00 (disabled)

ACK: (Acknowledge) 0x06

NAK: (Negative Acknowledge) 0x15

The following are general outlines of the ACK/NAK protocol. Items that are framed by brackets ( [ ] ) can either be disabled or enabled. LRC does not include STX, but it does include preamble, postamble, and ETX.

Symbol Data Output

TX to host: [STX] [preamble] SYMBOL DATA [postamble] [ETX] [LRC]

Response from host: ACK/NAK. Sent when LRC, ETX, postamble, or timeout (waiting for more data) are detected (if REQ is disabled) depending on what is enabled.

Commands from Host to Scanner

TX to Scanner: [STX] [ETX] [LRC]

Response from Scanner: ACK/NAK. Sent when LRC, ETX, or command-ending angle bracket ‘>’ are received, depending on what is enabled.

Command Response from Scanner to Host

TX to host: [STX] [preamble] COMMAND RESPONSE DATA [postamble] [ETX] [LRC]

Response from host: ACK/NAK. Sent when LRC, ETX, postamble, command-ending angle bracket ‘>’, or timeout (waiting for more data) are detected, depending on what is enabled.

As with Polling Mode , the scanner can optionally perform the REQ and RES event sequences in ACK/NAK mode. If the sender does not receive an ACK or NAK, it will send REQ to request such a response (if enabled). When the sender receives an ACK, too many NAKs, or times out (if already enabled), it will send a RES (if enabled) to terminate the transaction.

Polling Mode Options

Definition:

These parameters only take effect for Polling Mode on the main RS-232 or RS-422 ports (not on the Auxiliary Port), and are completely independent of the ACK/NAK Options .

The values of protocol characters can be changed, but the protocol events cannot be disabled. The polling mode address is configured in the command (see Poll Address on page 3-7).

Serial Cmd:

RES-NAK Defaults

RES: (Reset) 0x04 (disabled)

REQ: (Request) 0x05 (disabled)

STX: (Start of Text) 0x02 (disabled)

ETX: (End of Text) 0x03 (disabled)

ACK: (Acknowledge) 0x06

NAK: (Negative Acknowledge) 0x15

Auxiliary Port Protocol

Note: The Aux Port cannot be used when the host port is set to RS-422 or Multidrop. As with the host port parameters, the auxiliary terminal's settings (baud rate, parity, stop bits, and data bits) must be identical with those of the auxiliary device.

Usage: These commands set the communication parameters with the auxiliary port which can be used to configure menus, send data to the host, display data transmissions originating from the host of the scanner, and relay data from other scanners set in tandem (Daisy-Chained). If the scanner's host port needs to be dedicated to the host, but configuration must be done on the fly, the auxiliary port can be set to accept configuration changes by Command Processing.

Definition: An auxiliary port connects the scanner to a remote display or to other scanners that can display or transfer data. As with the host port parameters, the auxiliary terminal's settings (baud rate, parity, stop bits, and data bits) must be identical to those of the auxiliary device.

Aux Port Mode

Note: The Aux Port interacts only with the host port via the 25-pin port except when in Daisy Chain mode. When in Daisy Chain mode, the Aux Port will also interact with the configuration port (9-pin port) or the wiring box network ports.

Definition: Determines the flow of data between the auxiliary port device(s), the scanner, and the host.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Transparent 2 = Half Duplex 3 = Full Duplex 4 = Daisy Chain 5 = Command Processing

Transparent (Aux Port Mode)

Usage: Often used in conjunction with handheld scanners. Employs an auxiliary readout to detect mis-applied symbols.

Definition: In Transparent mode data is passed between the auxiliary port and the host. The scanner buffers data from the auxiliary port and echoes the keyed data on the auxiliary port.

Data Initiated from the Auxiliary Port

Auxiliary port data is passed through to the host whenever a return key is pressed at the auxiliary port or symbol data is sent.

Whenever Aux Port data is sent with symbol data, the Aux Port data will appear between the preamble and the symbol data.

Auxiliary port data to the host is always sent with a preamble and a postamble.

If the scanner is in a polled mode to the host, auxiliary port data will still pass through.

    B["Aux. Port"] --> C["Scanner"]
    B["Aux. Port"] --> C["Scanner"]

is the only command accepted by the scanner from the auxiliary port. All other commands will pass through to the host.

Data Initiated from the Scanner

Transmission to the auxiliary port occurs immediately upon a good read.

Scan data to the auxiliary port does not include a preamble or a postamble.

Communications with the auxiliary port is always in Point-to-Point protocol, even if the host is in a polled protocol mode.

Data Initiated from the Host

All host data is echoed to the auxiliary port in unpolled and polled mode.

Serial Cmd:

1 = Transparent

Half Duplex (Aux Port Mode)

Usage: Used to display symbol data on an auxiliary screen close to the scanner.

Definition: In Half Duplex mode all auxiliary port data and symbol data is sent directly to the host. Symbol data is displayed on the auxiliary port screen at the same time the data is sent to the host.

Data Initiated from the Auxiliary Port

Auxiliary port data to the host is ignored if the scanner is in a polled mode.

Auxiliary port data or scanned data is sent to the host whenever it is received.

Auxiliary port data is not echoed.

Auxiliary port data to the host is always sent without a preamble or a postamble.

Note: See also Daisy Chain Autoconfigure on page 3-19.

Usage: Used in applications where:

A symbol might be scanned in both ladder and picket fence directions.

A symbol may be present on multiple sides of a package.

Symbols are presented at different depths.

Definition: In a daisy chain application, scanners are connected in series or "daisy chain" and decoded data is relayed from one scanner to another on up to the host.

A master scanner has its host port linked to the host computer and its auxiliary port linked to the host port of the first secondary scanner in the chain. Thereafter, each secondary's auxiliary port is linked to the host port of the secondary that is further from the host in the daisy chain.

Each scanner in the daisy chain can be assigned an ID that accompanies any data that it sends.

Serial Cmd:

4 = Daisy Chain

Function: Before the master scanner times out, it checks its auxiliary port for data. It should be set to wait at least 20 ms for each secondary in the daisy chain. (See Read Cycle Timeout on page 4-16.) If no data is received within the read cycle timeout, the master sends a No Read message to the host. Otherwise the complete data is sent.

If for example the master scanner is set to timeout in 120 ms, the first secondary scanner downstream might be set to 100 ms, the next to 80 ms, and so forth, thus assuring that at least 20 ms elapses between transmissions. ^a

Daisy-chained scanners can send a series of symbols by enabling Multisymbol and a common multisymbol separator. If the master scanner does not receive the expected number of symbols, No Read messages are appended to the data string to make up the difference between the number of symbols enabled in Multisymbol and the number of symbols read.

For example, a master and two secondary scanners have Number of Symbols set to 3 and Multisymbol Separator defined as %. If the master and the first secondary scanner do not find symbols, but the next secondary scanner registers a good read, the transmitted results would be:

symbol data % No Read % No Read

a. The above example is based on the best case. Other factors such as baud rate, dynamic focus timing, number of characters in a given symbol, and the number of secondaries in the daisy chain can affect timing and may need to be included in your calculations for complete accuracy.

Daisy Chain (Aux Port Mode) (cont.)

Conditions: The conditions for a daisy chain application are as follows:

1. The master scanner's trigger must be Serial or External; the secondary scanners' triggers are configured for Serial.

2. All scanners are enabled to Daisy Chain mode.

3. Each scanner's auxiliary port must be connected to the Host port of its secondary scanner.

4. Each secondary scanner in the daisy chain must be set to send its data no less than 20ms before its preceding scanner.

5. All but the master scanner must have Postamble enabled and set to CR (^M) only.

6. All but the master scanner must have their No Read messages disabled.

7. If Multisymbol is enabled, Multisymbol Separator characters must match in all scanners and Number of Symbols must be set to number large enough to include all the symbols it may itself read plus the number of symbols that it will be expected to relay to the host or the next scanner up the line.

8. Symbology ID enable/disable must be the same in all scanners.

9. All but the master scanner must have their diagnostic warning messages disabled.

10. Daisy Chain ID Status enable/disable and the number of characters in Daisy Chain ID must be the same in all scanners.

Command Processing (Aux Port Mode)

Usage: Allows user to send configuration from the Host port or the Aux Port.

Definition: When enabled, Command Processing allows commands to be entered via the Aux Port. The following rules apply:

• Symbol data, including the serial trigger if used, will be transmitted to the last port from which a command was sent.
• If a reset occurs, all data will be transmitted to the host port.

Serial Cmd:

Options: 5 = Command Processing

Baud Rate (Aux Port)

Usage: Can be used to transfer data faster or match an auxiliary device.

Definition: The rate at which the scanner and host transfer data back and forth.

Serial Cmd:

Default: 9600

Options: 1 = 1200

$$ 2 = 2 4 0 0 $$

$$ 3 = 4 8 0 0 $$

$$ 4 = 9 6 0 0 $$

$$ 5 = 1 9. 2 \mathrm{K} $$

$$ 6 = 3 8. 4 \mathrm{K} $$

$$ 7 = 5 7. 6 \mathrm{K} $$

$$ 8 = 1 1 5. 2 \mathrm{K} $$

Parity (Aux Port)

Usage: Only changed if necessary to match host setting.

Definition: An error detection routine in which one data bit in each character is set to 1 or 0 so that the total number of 1 bits in the data field is even or odd.

Serial Cmd:

Default: Even

Options: 0 = None 1 = Even 2 = Odd

Stop Bits (Aux Port)

Usage: Only changed if necessary to match host setting.

Definition: Allows the user to select the last one or two bits in each character to indicate the end of the character.

Serial Cmd:

Default: One

Options: 0 = One 1 = Two

Auxiliary Port Protocol

Data Bits (Aux Port)

Usage: Only changed if necessary to match host setting.

Definition: Number of bits in each character.

Serial Cmd:

Default: Seven

Options: 0 = Seven 1 = Eight

Daisy Chain ID Status (Aux Port)

Note: Enable/disable and length must be the same in all scanners.

Usage: Used in a daisy chain setup in cases where the host needs to know which scanner in a daisy chain setup sent the data.

Definition: Each scanner in a daisy chain can be assigned a one or two character ID that will appear in front of decoded data and identify its source.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Daisy Chain ID (Aux Port)

Note: All secondary scanners must be set to Serial for Daisy Chain to function.

See Trigger on page 4-5.

Usage: Used in a daisy chain setup in cases where the host needs to know which scanner sent the data.

Definition: A one or two character prefix which identifies the particular daisy chain scanner from which the data is being sent.

Serial Cmd:

Default: 1/

Options: Any one or two ASCII characters.

Daisy Chain Autoconfigure

Note: This command is not available in ESP.

Usage: For quick setup and configuration of the daisy chain network.

Definition: Daisy Chain Autoconfigure is issued to the master scanner in the daisy chain and the software responds as follows:

• Counts the number of secondary scanners in the daisy chain.
• Assigns an internal ID number (1...n) to each secondary scanner, where the first secondary scanner is number 1 (and its own ID being a 0).
• Propagates the communications settings and the relevant operating modes of the master scanner to the host and auxiliary ports of each secondary scanner.
• Resets each secondary scanner.
• Verifies that each secondary scanner has acquired the new settings.

Serial Cmd:

When setting up a daisy chain operation, follow these steps:

1. Set the master (the scanner connected to the host) scanner to Serial.
   This sets all the scanners in the daisy chain to Serial when the command is carried out.
   Before Autoconfigure you must set the primary scanner to Serial (S):

graph LR
    A["Host"] --> B["Primary Scanner"]
    B --> C["Secondary Scanner"]
    C --> D["Secondary Scanner"]
    B -->|S| B
    C -->|S| C
    D -->|S| D

1. Send command.
2. If necessary, set the master scanner to Edge.
   After Autoconfigure you may set the primary scanner to Edge (S), but the other scanners must remain in Serial (S):

graph LR
    A["Host"] --> B["Primary Scanner"]
    B --> C["Secondary Scanner"]
    C --> D["Secondary Scanner"]
    B -->|E| B
    C -->|S| C
    D -->|S| D

Daisy Chain Scanner ID

Note: Scanner IDs can also be assigned in Daisy Chain (Aux Port Mode) (page 3-14).

Usage: This command provides a convenient way to assign custom daisy chain IDs to specific scanners that were assigned during the daisy chain autoconfigure process.

Definition: Assigns a new daisy chain ID to a daisy chain secondary scanner. The command is sent to the master scanner to configure the other secondary scanners.

Scanner Number

Definition: Specifies the target scanner (by sequential number) which will be receiving the new daisy chain ID. The master scanner is always 0 (zero). All secondary scanners are numbered 1...n in the order that they are connected.

Note: These numbers are for assigning IDs only and are not changeable.

Serial Cmd:

Options: 1.....n (0 for the master scanner)

Scanner ID

Definition: A two-character user-defined ASCII message identifying a scanner in the daisy chain.

Serial Cmd:

Default: Sequential numbering of scanner units resulting from the Daisy Chain Autoconfigure command; for example: ID Master = 1/; ID Scanner 1 = 2/; ID Scanner 2 = 3/; etc.

Options: Any two characters except NUL, <, >, or ,.

Note: See also Chapter 13, Output Format.

Note: After a secondary scanner accepts a new ID, it automatically invokes a reset-with-save command.

Auxiliary/Configuration Port System Data

Note: Do not use Auxiliary Port in a daisy chain operation.

Auxiliary Port Status

Note: This command only applies if Auxiliary Port Mode is set to Command Processing.

See Command Processing (Aux Port Mode) on page 3-16.

Usage: To check symbol data and error messages via the Aux Port.

Definition: When enabled, system data, including decoded data and diagnostic warning messages, will be routed to the Aux Port.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Configuration Port Status

Usage: To check symbol data and error messages via the configuration port.

Definition: When enabled, system data, including decoded data and diagnostic warning messages, will be routed to the 9-pin configuration port.

Serial Cmd:

Default: Enabled

Options: 0 = Disabled

1 = Enabled

Important: Enable Data Out 9-Pin when using the configuration port.

Preamble

Preamble

Preamble Status

Usage: Used for identifying and controlling incoming data. For example, defining the preamble as a carriage return and a line feed causes each decoded message to be displayed on its own line.

Definition: Defines a one to four character data string that can be added to the front of the decoded data.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled (within any protocol)

Preamble Character(s)

Serial Cmd:

Default: ^M corresponds to: carriage return/NUL/NUL/NUL.

Options: Up to four user-defined ASCII characters, including control characters.

Within a Serial Command

To enter control characters within a serial command, hold down the control key while typing the desired character.

Example: to enter ^M

Within an Embedded Menu

Control characters entered on the command line are displayed in the menu as mnemonic characters, such as: .

To enter a control character from within an embedded menu, first type in a space (with the space key). This has the effect of allowing the control key to be recognized as a part of the control character. Next hold down the control key while typing the desired character.

Example: Space CTRL-m to enter ^M

Postamble

Postamble Status

Usage: Used for identifying and controlling incoming data. For example, defining the postamble as a carriage return and a line feed causes each decoded message to be displayed on its own line.

Definition: Defines a one- to four-character data string that can be added to the end of the decoded data.

Serial Cmd:

Default: Enabled

Options: 0 = Disabled 1 = Enabled

Postamble Character(s)

Serial Cmd:

Default: ^M^J corresponds to carriage return/line feed/NUL/NUL, as displayed in the menu.

Options: Up to four user-defined ASCII characters, including control characters.

Within a Serial Command

To enter control characters within a serial command, hold down the control key while typing the desired character.

Example: to enter ^M^J.

Within an Embedded Menu

Control characters entered on the command line are displayed in the menu as mnemonic characters, such as:

To enter a control character from within an embedded menu, first type in a space (with the space key). This has the effect of allowing the control key to be recognized as a part of the control character. Next hold down the control key while typing the desired character.

Example: Space CTRL-m Space CTRL-j to enter ^M^J.

LRC Status

(Longitudinal Redundancy Check)

Usage: Used when extra data integrity is required.

Definition: An error-checking routine that verifies the accuracy of transmissions. It is the exclusive OR of all characters following the STX (start of text) up to and including the ETX (end of text). What this means is that the binary representation of all the characters in a transmissions are cumulatively added in a column and each resulting odd integer is assigned a 1 and each even integer a 0 (two 1s = 0, two 0s = 0, a 1 and a 0 = 1). The extra LRC character is then appended to the transmission and the receiver connected to the host port performs the same addition and compares the results.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Intercharacter Delay

Usage: Used only when a host cannot receive data quickly enough and there is enough time between symbols to allow data to be completely transferred. It is rarely used since any setting other than zero will slow down communications. For example, a 200 setting will result in a 1/5 second delay between each character that is transmitted.

Definition: The time interval in milliseconds between individual characters transmitted from the scanner to the host.

Serial Cmd:

Default: 0

Options: 0 to 255 (in milliseconds)

Note: 0 causes no delay between characters.

Response Timeout

Response Timeout

Usage: Used only when a response is required from the host. While in Multidrop, if the scanner does not receive an ACK or NAK from the host after sending polled data, it will act on a fault. The scanner can be set to wait indefinitely by setting Response Timeout to zero.

Definition: Time the scanner will wait before timing out if ACK, NAK, and ETX are enabled, and a host response is expected.

Serial Cmd:

Default: 2 (x 10 = 20 ms)

Options: 0 to 255 in 10 ms increments (0 to 2.55 seconds) (A 0 setting causes an indefinite wait.)

After you've established communications and completed basic read rate testing, you will need to address the spatial and timing parameters associated with your application. In a typical operation, a bar-coded item moves along a line past a scanner. A trigger or timer activates a read cycle during which the scanner actively searches for symbols. You will need to decide how to initiate the read cycle and how and when to end it.

Note: When assigning characters in user-defined fields, the characters NUL, <, >, and, can only be entered through embedded menus, not through ESP or serial commands.

Note: You can learn the current setting of any parameter by inserting a question mark after the number, as in . To see all K commands, send .

Note on Serial Commands: To preserve continuity with other Microscan products, some serial configuration commands may include 0s or 1s as placeholders. In order for a these commands to be implemented, the parameter values or a comma must be included.

Multisymbol

Usage: Multisymbol is commonly used in shipping applications where a shipping symbol contains individual symbols for part number, quantity, etc. This feature allows one trigger to pick up all the symbols. AIAG and EAN-128 are two application standards that address this need.

Definition: Multisymbol allows the user to define up to 12 symbols that can be read in a single read cycle.

Conditions: The following conditions apply:

1. Each symbol must be different to be read unless they appear in the scan line at the same time.
2. The maximum number of characters in a read cycle is 32520 for all symbols.
3. The maximum number of characters the scanner can transmit is calculated by: Preamble + maximum number of symbols * (aux id + symbology id + maximum symbol length + quality output + ((number of insertion cells x cell length) + separator) + postamble + LRC = 37425.
4. All No Read messages are posted at the end of the data string.
5. If more than one symbol is within the scan beam at the same time, symbol data may not be displayed in the order of appearance.
6. If Matchcode Type is set to Sequential or if Trigger is set to Continuous Read 1 Output, Number of Symbols will default to 1 (if set to any number greater than 1).

Number of Symbols

Definition: Number of Symbols is the number of different symbols that can be read in a single read cycle.

Conditions: The following conditions apply:

1. When Number of Symbols is set to Single, the read cycle ends when one symbol is decoded and output.
2. When Number of Symbols is set to Multiple, all decoded symbol data (for both the same and different symbols) are output while the read cycle is active and/or no timeout has occurred.

Serial Cmd:

Default: 1

Options 1 to 12

Multisymbol

Multisymbol Separator

Usage: Used to delimit or separate data fields with a user defined character.

Definition: The character that's inserted between each symbol scanned when Multisymbol is set to any number greater than 1.

ESP: To select a new multisymbol separator, double-click on Separator and select a character in the popup window.

Parameters Read Cycle Multisymbol Number of Symbols 1 Multisymbol Separator Trigger Serial Trigger End of Read Cycle Decodes Before Output Optoelectric Control Reader Setup Laser Setup Raster Setup STX NUL SOH STX ETX EOT ENQ ACK BEL BS HT LF VT FF CR SO SI DC1 DC2 DC3 DC4 NAK SYN ETB CAN EM SUB ESC FS GS RS US SP Click 'Delete' to remove characters.

Serial Cmd:

Note: If Multisymbol Separator has been changed to any character other than the default comma and you wish to re-define the separator as a comma, use ESP or the embedded menu.

Default: , (comma)

Options: Any available ASCII character, except NUL, <, >, and , .

Trigger

Trigger Mode

Note: When doing calibration or read rate testing, the current trigger setting will be disregarded.

Note: This command does not need to be followed by an command.

Definition: The type of trigger event that will initiate the read cycle.

Serial Cmd:

Default: Continuous Read

Options: 0 = Continuous Read

1 = Continuous Read 1 Output

2 = External Level

3 = External Edge

4 = Serial Data

Usage: Continuous Read is useful in testing symbol readability or scanner functions. It is not recommended for normal operations.

Definition: In Continuous Read, trigger input options are disabled, the scanner is always in the read cycle, and it will attempt to decode and output every scan crossing a symbol. When To Output and No Read options have no effect on Continuous Read.

Serial Cmd:

Trigger

Continuous Read 1 Output

Usage: Continuous Read 1 Output can be useful in applications where it is not feasible to use a trigger and all succeeding symbols contain different information. It is also effective in applications where the objects are hand-presented.

Definition: In Continuous Read 1 Output the scanner self-triggers whenever it decodes a new symbol or a timeout occurs.

If End Of Read Cycle is set to Timeout and the symbol doesn't change, the scanner will repeat the output at the end of each timeout period. For example, if Timeout is set to one second, the scanner sends the symbol data immediately and repeats the output at intervals of one second for as long as the symbol continues to be scanned.

If End Of Read Cycle is set to New Trigger, the scanner will send the current symbol data immediately, but send it only once. A new symbol appearing in the scanner's range will be read and sent immediately provided it is not identical to the previous symbol read.

Serial Cmd:

Caution: In automated environments, Continuous Read 1 Output is not recommended because there is no one to verify that a symbol was missed.

Note: If Trigger is set to Continuous Read 1 Output, Number of Symbols will default back to 1 (if set to any number greater than 1).

External Trigger Level

graph TD
    A["Object detector"] --> B["1"]
    B --> C["Object detector"]
    D["Start"] --> E["Initiate Read Cycle: Object #1, moving in front of the detector beam, causes a change in the trigger state, which initiates the read cycle."]
    F["End"] --> G["End Read Cycle: The same object, moving out of the detector beam, causes another change in the trigger state, which ends the read cycle."]

Usage: This mode is effective in an application where the speeds of the conveying apparatus are variable and the time the scanner spends scanning each object is not predictable. It also allows the user to determine if a No Read has occurred.

Definition: External Level allows the read cycle to begin when a trigger (change of state) from an external sensing device is received. The read cycle endures until the object moves out of the sensor range and the active trigger state changes again.

Serial Cmd:

Important: Level and Edge apply to the active logic state (Open or Closed) that exists while the object is in a read cycle, between the rising edge and falling edge. Rising edge is the trigger signal associated with the appearance of an object. Falling edge is the trigger signal associated with the subsequent disappearance of the object.

Note: In External Trigger Level, sending a non-delimited start serial character will start a read cycle and sending a non-delimited stop serial character will end it. See Start Character (Non-Delimited) and Stop Character (Non-Delimited) on page 4-13.

    A["Start"] --> B["Object detector 1"]
    B --> C["Initiate Read Cycle: Object #1, moving in front of the detector beam, causes a change in the trigger state, which initiates the read cycle."]
    D["Start"] --> E["Object detector 2"]
    E --> F["Initiate Second Read Cycle: Object #2, moving in front of the detector beam, causes another change in the trigger state. This signal initiates a new read cycle and ends the previous read cycle unless Timeout is enabled and a good read or timeout has not occurred."]

Usage: This mode is highly recommended in any application where conveying speed is constant or if spacing, object size, or timeouts are consistent.

Definition: External Trigger Edge, as with Level, allows the read cycle to begin when a trigger (change of state) from an external sensing device is received. However, the passing of an object out of sensor range does not end the read cycle. The read cycle ends with a good read output or, depending on End of Read Cycle setting, a timeout or new trigger occurs. External Trigger Edge, as with Level, allows the read cycle to begin when a trigger (change of state) from an external sensing device is received. However, the passing of an object out of sensor range does not end the read cycle. The read cycle ends with a good read or with a No Read when a No Decode Timeout occurs.

Serial Cmd:

Important: Level and Edge apply to the active logic state (Open or Closed) that exists while the object is in a read cycle, between the rising edge and falling edge. Rising edge is the trigger signal associated with the appearance of an object. Falling edge is the trigger signal associated with the subsequent disappearance of the object.

Note: In External Trigger Level, sending a non-delimited start serial character will start a read cycle and sending a non-delimited stop serial character will end it. See Start Character (Non-Delimited) and Stop Character (Non-Delimited) on page 4-13.

Serial Data

Usage: Serial Data is effective in a highly controlled environment where the host knows precisely when the object is in the scan zone. It is also useful in determining if a No Read has occurred.

Definition: In Serial Data, the scanner accepts an ASCII character from the host or controlling device as a trigger to start a read cycle. A Serial Data trigger behaves the same as an External Edge trigger.

Serial Cmd:

Serial Data and External Edge

Usage: Serial Data and External Edge is seldom used but can be useful in an application that primarily uses an external sensing device but occasionally needs to be manually triggered. An auxiliary terminal can be connected to the Aux Port so the user can send the serial trigger character through the scanner to the host.

Definition: In this mode the scanner accepts either a serial ASCII character or an external trigger pulse to start the read cycle.

Serial Cmd:

Trigger

Trigger Filter Duration

Usage: Trigger Filter Duration is useful where trigger bounce could cause false triggers.

Definition: Trigger Filter Duration can prevent trigger bounce from falsely triggering the scanner by limiting the time in which trigger pulses can be received.

Serial Cmd:

Default: 320 (10 ms)

Options: 0 to 65535 (0 to 2.047s in 31.25 s steps)

External Trigger State

Note: External Level, External Edge, or Serial Data and External Edge trigger mode must be enabled for External Trigger to take effect.

Usage: Users can select the trigger state that will operate with their systems. (If using an object detector, use Active Closed.)

Definition: When enabled for Active Closed the triggering device imposes a current on the optoisolator to activate the read cycle. When enabled for Active Open the triggering device interrupts the current to the optoisolator to activate the read cycle.

Serial Cmd:

Default: Active closed

Options: 0 = Active open 1 = Active closed

Serial Trigger

Serial Trigger

Usage:	Useful in applications where a read cycle needs to be initiated and/or ended by user-defined serial characters.
Definition:	An online host command composed of a single ASCII host serial trigger character that initiates or ends the read cycle.Trigger characters are of two types: delimited and non-delimited. A delimited character is enclosed within angle bracket delimiters <> .A non-delimited trigger character is one that either starts or ends the read cycle and is NOT enclosed by delimiters such as <> .

Rules for Trigger Modes

• In External Edge the scanner looks only for the Start Trigger Character and ignores any End Trigger Character that may be defined.
• In External Level, the Start Trigger Character begins the read cycle and an End Trigger Character ends it. Note that even after a symbol has been decoded and the data transmitted, the scanner remains in External Level trigger read cycle until a Stop character is received.
• In Serial Data and External Edge trigger mode, command, either a Start Trigger Character or a hardware trigger can start an Edge trigger read cycle.

Serial Trigger Character (Delimited)

Usage: Useful in applications where a single serial character enclosed in angle brackets initiates the read cycle.

Definition: A delimited trigger character is one that starts the read cycle, is enclosed by delimiters such as <>, and can only be sent when the trigger mode is set to Serial Data or Serial Data and External Edge.

Serial Cmd:

Default: ^] (corresponds to displayed in the embedded menu)

Options: Any single ASCII character, including control characters, except NUL (00 in hex), an existing host command character, or an online protocol character. Control characters entered on the command line are displayed in the menu as mnemonic characters.

Note: Serial Data or Serial Data and External Edge triggering mode must be enabled for Serial Trigger Character to take effect.

Start Character (Non-Delimited)

Usage: Useful in applications where a different character is required to start a read cycle. Works with External Edge, External Level, and Serial Data and External Edge.

Definition: A single ASCII host serial trigger character that starts the read cycle and is not enclosed by delimiters such as < and >.

Serial Cmd:

Default: NUL (disabled)

Options: Two hex digits representing an ASCII character except <, >, XON, and XOFF.

Stop Character (Non-Delimited)

Usage: Useful in applications where a different character is required to end a read cycle. Works with External Level only.

Definition: A single ASCII host serial trigger character that ends the read cycle and is not enclosed by delimiters such as < and >.

Serial Cmd:

Default: NUL (disabled)

Options: Two hex digits representing an ASCII character except <, >, XON, and XOFF.

End of Read Cycle

Note: When to Output must be set to End of Read Cycle before this command can be active.

Definition: The read cycle is the time during which the scanner will attempt to read and decode a symbol. At the end of a read cycle the scanner stops reading symbols and sends the symbol data or No Read message to the host.

End of Read Cycle Mode

Definition: A read cycle can be terminated by a new trigger, a timeout, or a combination of both.

Serial Cmd:

Default: Timeout

Options: 0 = Timeout 1 = New Trigger 2 = Timeout and New Trigger

Note: When operating in Continuous Read or Continuous Read 1 Output, the scanner is always in the read cycle.

Timeout

Usage: Typically used with Serial or Edge and Continuous One.

It is effective in highly controlled applications when the maximum length of time between objects can be predicted. It assures that a read cycle ends before the next bar-coded object appears, giving the system extra time to decode and transmit the data to the host.

Definition: Timeout ends the read cycle when the time set in Read Cycle Timeout elapses or "times out."

If in Continuous Read 1 Output, a timeout initiates a new read cycle and allows the same symbol to be read again.

With either External Edge, Serial Data, or Serial Data and External Edge enabled, a timeout ends the read cycle and symbol data or a No Read message is sent to the host.

With External Level enabled, the read cycle does not end until the falling edge trigger or a timeout occurs. The next read cycle does not begin until the next rising edge trigger.

New Trigger

Usage: New Trigger is an effective way to end a read cycle when objects move past the scanner at irregular intervals (not timing-dependent).

Definition: New Trigger ends the current read cycle and initiates a new one when a new trigger occurs. New Trigger refers only to a "rising edge" trigger. With either External Edge, Serial, or Serial or Edge enabled, an edge or serial trigger ends a read cycle and initiates the next read cycle. In the case of External Level, a falling edge trigger ends the read cycle but the next read cycle does not begin until the occurrence of the next rising edge trigger.

Note: When New Trigger is enabled and if not in External Level mode, Laser On/Off will have no effect. When No Reads occur, the laser will remain on.

Timeout and New Trigger

Usage: Useful in applications that require an alternative way to end the read cycle. For example, if an assembly line should stop completely or the intervals between objects are highly irregular.

Definition: Timeout and New Trigger is identical to Timeout, except that a timeout or a new trigger (whichever occurs first) ends the read cycle.

End of Read Cycle

Read Cycle Timeout

Usage: Useful in many tightly controlled applications which require a read cycle to end before the next object appears and therefore need the flexibility of a timeout adjustment.

Definition: Read Cycle Timeout is the time span of the read cycle and is represented in 10 ms increments. It is used in conjunction with External Edge or Serial Trigger.

Serial Cmd:

Default: 100 (x 10 ms)

Options: 0 to 65535. (Divide any positive number entered by 100 to determine the time in seconds.)

Note: A minimum setting of 2 is recommended.

Note: Timeout or Timeout or New Trigger under End of Read Cycle must be enabled for Read Cycle Timeout to take effect.

Good Decode Reads

Usage: This is a very useful feature to increase reliability of reads for symbologies that do not have internal error checking such as Pharmacode.

Definition: The number of decodes (from 1 to 31) required per symbol before a symbol's decoded data is sent. It requires the scanner to successfully decode a symbol a designated number of times (not necessarily consecutively) before it is sent. If it doesn't achieve the number of good reads during the read cycle, then a No Read will be sent.

Note: Higher settings will decrease throughput speed.

Serial Cmd:

Default: 1

Options: 1 to 31

Good Decode Output Mode

Definition: Affects how the scanner counts symbols that it reads successfully.

Serial Cmd:

Default: Non-Consecutive

Options: 0 = Non-Consecutive 1 = Consecutive

The settings in this section are typically adjusted by Calibration, or by qualified technicians. They are included here for special applications. Before making changes to individual commands in this section, it would be advisable to make a written record of current settings.

Gain Adjustment

Usage: Can be useful for fine-tuning gain or when portions of analog signals spike as in the case of specular reflection or extraneous noise. Caution: Changes to Gain are typically done by qualified technicians in Calibration. See Chapter 9, Calibration.

Definition: Sets a voltage amplitude value for the analog circuitry.

Serial Cmd:

Default: Default is 40 (nominal). Gain is optimized at the factory before shipment; the default value may not be 40.

Options: 0 to 255

AGC Mode

Definition: Tracks peak signals and selects an amplitude reference point to sample the analog signals for converting to digital.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Focus

Focus is generally set during the Calibration routine (see Chapter 9, Calibration). However, in certain applications involving specific focal lengths, manual control of focus may be appropriate.

Focus Position

Definition: Allows the user to change the focus position setting.

Serial Cmd:

Default: 0

Options: 0 to 40

Scan Speed

Scan Speed

Definition: Allows the user to set the number of scans per second by controlling the spinning mirror motor speed.

Serial Cmd:

Default: 400

Options: 400 to 1000

Automatic Gain Control (AGC) Settings

Important: AGC settings apply to both AGC and symbol detection.

Symbol Detect Status

Usage: During the read cycle, the scanner counts the number of bar and space transitions defined in the Transition Counter. If the count matches or exceeds the threshold, the scanner will perform AGC routines.

Definition: AGC is the acronym for Automatic Gain Control. AGC increases the depth of field by attempting to maintain signal strength at a constant level regardless of the range of the symbol.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Minimum Number of Transitions

Usage: Can be useful in certain application where extraneous objects in the field of view might require a higher threshold.

Definition: Determines the number of bar/space transitions that must be read before a symbol is considered present and AGC can be resolved.

Serial Cmd:

Default: 14

Options: 1 to 255

Maximum Element

Maximum Element

Definition: Maximum Element represents the maximum bar element width that is allowed before a video reset occurs (default to white).

Caution: Do not change this parameter unless instructed by a Microscan representative.

Serial Cmd:

Default: 400 (x 0.01% of scan)

Options: 50 to 5000

Tracking Adjustment

Definition: Sets a tracking value for the scanner's analog circuitry. Changes to tracking adjustment should be made by Autocalibration.

Code 39

Usage: Code 39 is considered the standard for non-retail applications.

Definition: An alphanumeric symbol with unique start/stop symbol patterns, composed of 9 black and white elements per character, of which 3 are wide.

Code 39 Status

Serial Cmd:

Default: Enabled

Note: This is the only symbol type enabled by default.

Options: 0 = Disabled 1 = Enabled

Check Character Status (Code 39)

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Check Character Output (Code 39)

Usage: Check Character Output Status, added to the symbol, provides additional security.

Definition: When enabled, the check character is read and sent along with the symbol data. When disabled, symbol data is sent without the check character.

Note: With Check Character Output Status and an External or Serial trigger option enabled, an invalid check character calculation will cause a No Read message to be transmitted at the end of the read cycle.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Large Intercharacter Gap (Code 39)

Usage: Large Intercharacter Gap is helpful for reading symbols that are printed out of specification.

Caution: Do not use Large Intercharacter Gap with Narrow Margins enabled since a large intercharacter gap (over 3x) could cause a narrow margins (5x) to be interpreted as an intercharacter gap.

Definition: When enabled, the scanner can read symbols with gaps between symbol characters that exceed three times (3x) the narrow element width.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Fixed Symbol Length Status (Code 39)

Usage: Helps prevent truncations and increases data integrity by ensuring that only a fixed symbol length will be accepted.

Definition: When enabled, the scanner will check the symbol length against the symbol length field. If disabled, any length is considered a valid symbol.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Symbol Length (Code 39)

Definition: Specifies the exact number of characters that the scanner will recognize (this does not include start and stop and check character characters). The scanner ignores any symbol not having the specified length.

Serial Cmd:

Default: 10

Default: 1 to 128

Full ASCII Set (Code 39)

Usage: Must be enabled when reading characters outside the standard character set (0-9, A-Z, etc.)

User must know in advance whether or not to use Full ASCII Set option. Since Full ASCII Set requires two symbol words to encode one character, it is less efficient.

Definition: Standard Code 39 encodes 43 characters; zero through nine, capital "A" through capital "Z", minus symbol, plus symbol, forward slash, space, decimal point, dollar sign and percent symbol. When Full ASCII Set is enabled, the scanner can read the full ASCII character set, from 0 to 255.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Code 128/EAN-128

Usage: Code 128/EAN-128 is a smaller symbology, and is useful in applications with tight spots and high security needs.

Definition: A very dense alphanumeric symbology. It encodes all 128 ASCII characters; it is continuous, has variable length, and uses multiple element widths measured edge to edge.

Code 128 Status

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled (Serial Standard) 2 = Edge 3 = Serial Standard and Edge

Note: Code 128 must be Enabled for EAN-128 to function.

Fixed Symbol Length Status (Code 128)

Definition: When enabled, the scanner will check the symbol length against the symbol length field. When disabled, any length is considered a valid symbol.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Symbol Length (Code 128)

Usage: Fixed Symbol Length helps prevent truncations and increases data integrity by ensuring that only one symbol length will be accepted.

Definition: Specifies the exact number of characters that the scanner will recognize (this does not include start and stop and check characters). The scanner ignores any symbol not having the specified length.

Serial Cmd:

Default: 10

Options: 1 to 128

Note: Fixed Symbol Length Status must be enabled for Symbol Length to take effect.

EAN-128 Status

Usage: Sometimes called the “shipping code,” it is used as a standard to track a product from site to site with a single symbol that contains categories of information identifiable across industries worldwide.

Definition: A subset of Code 128, with extended features using application identifiers to define the meaning and format of fields that immediately follow them. For more information, refer to the AIM website at:

http://www.aimglobal.org/standards/aimpubs.asp

Serial Cmd:

Note: Code 128 serial command fields for K474 precede EAN-128.

Default: Disabled

Options: 0 = Disabled 1 = Enabled 2 = Required

If set to Enabled, symbols can be read with or without a function 1 character in the first position.

If set to Required, the symbol must have a function 1 in the first position and conform to EAN format in order to decode the symbol.

Note: Code 128 must also be Enabled for EAN-128 to function.

Output Format (EAN-128)

Usage:	Application Record is useful in applications in which the software can use application record formatting to help automate the processing of its EAN-128 data.
Definition:	Offers an option between Standard EAN-128 and Application Record format.
Serial Cmd:

Default: Standard

Options: 0 = Standard

1 = Application Record

Standard:

When set to Standard, EAN-128 application identifiers and data fields are sent, but none of the formatting (separators, parentheses, padding) will be included.

Application Record:

Application Record is a variation of EAN-128 that allows the user to define separators between data fields, enclose application identifiers in parentheses, and enable padding (zeros) for variable length fields.

Note: If an illegal Application Record format is detected, the scanner will process it as a No Read and output a No Read message (if enabled).

Application Record Separator Status (EAN-128)

Definition: When enabled, a separator character is inserted between application records.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Application Record Separator Character (EAN-128)

Definition: Defines an ASCII character as an application record separator.

Serial Cmd:

Default: , (comma)

Options: User Defined ASCII character

Note: Output Format must be set to Application Record before this parameter can take effect.

Application Record Brackets Status (EAN-128)

Definition: When enabled, parentheses ( ) are added to enclose application identifiers.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Note: Output Format must be set to Application Record before this parameter can take effect.

Application Record Padding Status (EAN-128)

Definition: Padding is the insertion of zeros to make up the maximum length of a variable application record data field, except for the last field which does not require padding.

When enabled, padding is included. When disabled, padding is omitted.

Note: Padding is never added to fixed length fields or to the last data field of a symbol. Enabling or disabling Record Padding will have no effect on these.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Note: Output Format must be set to Application Record before this parameter can take effect.

Minimum Ratio Distance (Code 128)

Definition: Determines the error tolerance level.

Normal enforces a requirement for normal error tolerance.

High enforces a requirement for high element-to-element quality.

Highest enforces a requirement for very high element-to-element quality.

Serial Cmd:

Default: Normal

Options: 0 = Normal 1 = High 2 = Highest

Interleaved 2 of 5

Usage: Interleaved 2 of 5 has been popular because it is the most dense symbol for printing numeric characters less than 10 characters in length; however, Microscan does not recommend this symbology for any new applications because of inherent problems (truncation, for example).

Definition: A dense, continuous, self-checking, numeric symbology. Characters are paired together so that each character has five elements, two wide and three narrow, representing numbers 0 through 9, with the bars representing the first character and the interleaved spaces representing the second character. (A check digit is highly recommended.)

Important: You must set Symbol Length in order to decode I 2/5 symbols.

Interleaved 2 of 5 Status

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Check Digit Status (Interleaved 2 of 5)

Usage: Typically not used but can be enabled for additional security in applications where the host requires redundant check digit verification.

Definition: An error correcting routine in which the check digit character is added.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Check Digit Output Status (Interleaved 2 of 5)

Definition: When enabled, a check digit character is sent along with the bar symbol data for added data security.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Symbol Length #1 (Interleaved 2 of 5)

Usage: With I–2/5, two symbol lengths can be defined. When using only one symbol length in an application, setting Symbol Length #2 to 0 (zero) to ensure data integrity is recommended.

Definition: Allows user to define the symbol length. Because I–2/5 is a continuous symbology, it is prone to substitution errors. Hence, a symbol length must be defined and a symbol must contain an even number of digits.

Note: If start, stop or check digits are used, they are not included in the symbol length count.

Serial Cmd:

Default: 10

Options: 0 to 128, even

Note: Since I 2/5 characters are paired, symbol length must be set to an even number. If Check Digit is enabled, add 2 to your symbol length. For example, if your symbol is 10 characters plus a check digit, then enable Symbol Length for 12.

Note: Typically, when printing an I 2/5 symbol with an odd number of digits, a 0 will be added as the first character. Note: If both Symbol Length #1 and Symbol Length #2 are set to 0, then I-2 of 5 will be variable.

Symbol Length #2 (Interleaved 2 of 5)

Usage: If using a second symbol, a zero or any even symbol length from 2 to 64 may be specified. If not using a second symbol, set Symbol Length #2 to 0 to ensure data integrity.

Definition: Allows user to define a second symbol length for 1–2/5.

Serial Cmd:

Default: 6

Options: 0 to 128, even

Since I 2/5 characters are paired, symbol length must be set to an even number. If Check Digit is enabled, add 2 to your symbol length. For example, if your symbol is 10 characters plus a check digit, then enable Symbol Length for 12.

Note: Typically, when printing an I 2/5 symbol with an odd number of digits, a 0 will be added as the first character.

Note: If both Symbol Length #1 and Symbol Length #2 are set to 0, then I-2 of 5 will be variable.

Guard Bar (Interleaved 2 of 5)

Note: Whenever Guard Bar is enabled, the presence of guard bars is required for decoding to take place.

Usage: Useful when I 2 of 5 multisymbols are enabled to prevent false data output. This typically occurs with highly tilted or skewed symbols.

Definition: A guard bar is a heavy bar, at least 2 times the width of the wide bar, surrounding the printed 12 of 5 symbol and helping to prevent false reads.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Range Mode (Interleaved 2 of 5)

Note: Whenever Guard Bar is enabled, the presence of guard bars is required for decoding to take place.

Definition: When enabled, this feature causes symbol length # 1 and symbol length # 2 to form of a range of lengths that can be decoded.

For example, if symbol lengths of 10 and 6 are enabled, those are the lengths that can be decoded. Note that either length can serve as the minimum or maximum.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Codabar

Usage: Used in photo-finishing and library applications. Used in some medical applications at one time, but not typically used in newer applications. Definition: Codabar is a 16-character set (0 through 9, and the characters \$, :, /, ., +, and -) with start/stop codes and at least two distinctly different bar widths.

Codabar Status

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Start and Stop Match Status (Codabar)

Usage: Used to increase security of symbology.

Definition: Requires the Codabar start and stop characters (a, b, c, or d) to match before a valid read can occur.

Serial Cmd:

Default: Enabled

Options: 0 = Disabled 1 = Enabled

Start and Stop Output Status (Codabar)

Usage: Used to verify matching.

Definition: Causes the start and stop characters to be transmitted with symbol data.

Serial Cmd:

Default: Enabled

Options: 0 = Disabled 1 = Enabled

Codabar

Large Intercharacter Gap (Codabar)

Usage: It is helpful for reading symbols that are printed out of specification.

Caution: Do not use Large Intercharacter Gap with Narrow Margins enabled since enabling Large Intercharacter Gap (over 3x) could cause a narrow margins (5x) to be interpreted as an intercharacter gap.

Definition: Instructs the scanner to read symbols with gaps between characters exceeding three times the narrow element width.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Fixed Symbol Length Status (Codabar)

Usage: Fixed Symbol Length helps prevent truncations and increases data integrity by ensuring that only one symbol length will be accepted.

Definition: When enabled, the scanner will check the symbol length against the fixed symbol length field. When disabled, any length would be considered a valid symbol.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Symbol Length (Codabar)

Definition: Specifies the exact number of characters that the scanner will recognize (this does not include start and stop and check character characters). The scanner ignores any symbol not having the specified length.

Serial Cmd:

Default: 10

Options: 1 to 128

Note: Fixed Symbol Length Status must be enabled for Symbol Length to take effect.

Note: Because of symbology limitations, setting Symbol Length to any number less than four will produce undetermined results.

Check Character Type (Codabar)

Definition: Allows the user to select the check character type Codabar will use.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled

1 = Modulus 16

2 = NW 7

3 = Both

Modulus 16: Used in the photo-finishing market.

NW 7: Used in Japanese markets.

Check Character Output Status (Codabar)

Usage: For additional security a check character can be added to the symbol.

Definition: When enabled, the check character character is sent along with the symbol data. When disabled, symbol data is sent without the check character.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

UPC/EAN

UPC/EAN

Usage: Used primarily in POS application in the retail industry. It is commonly used in applications in combination with Matchcode when there is a need to verify that the right product is being placed in the right packaging.

Definition: UPC (Universal Product Code) is a fixed length numeric, continuous symbology. UPC can have two- or five-digit supplemental symbol data following the normal symbol. The U.P.C., Version A (UPC-A) symbol is used to encode a 12 digit number. The first digit is the number system character, the next five are the manufacturer number, the next five are the product number, and the last digit is the checksum character.

When enabled, the scanner will read UPC-A and UPC-E only.

UPC Status

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

EAN Status

Usage: UPC/EAN is the European version of the UPC symbology and is used in European market applications.

Note: UPC must be enabled for EAN to take effect.

Definition: EAN is a subset of UPC. When enabled, the scanner will read UPC version A, UPC version E, EAN 13, and EAN 8. It also appends a leading zero to UPC version A symbol information and transmits 13 digits. If transmitting 13 digits when reading UPC version A symbols is not desired, disable UPC/EAN.

Note: The extra character identifies the country of origin.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Supplemental Status (UPC/EAN)

Usage: Reads Supplementals typically used in publications and documentation.

Definition: A supplemental is a 2 or 5 digit symbol appended to the main symbol.

When set to Enabled or Required, the scanner reads supplemental symbol data that has been appended to the standard UPC or EAN codes.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled

1 = Enabled

2 = Required

Disabled: UPC Supplementals will not be decoded.

Enabled: When enabled, the scanner will try to decode a main and a supplemental.

However, if a supplemental is not decoded, at the end of the read cycle, the main will be sent by itself. The UPC main and supplemental symbols are considered to be one symbol and will be treated as such.

Required: When set to Required and either the main or supplemental symbol is not read, a single No Read condition results. The UPC main and supplemental symbols are treated as one symbol.

For example, if Supplementals is set to Required, Separator is enabled, and an asterisk is defined as the UPC separator character, then the data will be displayed as: MAIN * SUPPLEMENTAL.

Note: Under no circumstances will supplemental symbol data be sent without a main symbol.

Note: If additional symbols—other than the main or supplemental—will be read in the same read cycle, Number of Symbols should be set accordingly.

Separator Status (UPC/EAN)

Usage: Allows user to distinguish between the main and Supplemental symbols.

Definition: Allows the user to insert a character between the standard UPC or UPC/EAN symbol and the supplemental symbol when Supplementals is set to Enabled or Required.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

UPC/EAN

Separator Character (UPC/EAN)

Note: If Separator Character has been changed to any other character and you wish to redefine the separator as a comma, you will need to use ESP or the embedded menu.

Note: Whenever Separator Character is defined as a comma (,) sending a command will return the current settings, including the separator character comma which appears after the separator status comma.

Usage: As required by the application.

Definition: Allows the user to change the separator character from a comma to a new character.

Serial Cmd:

Default: , (comma)

Options: Any ASCII character

PDF417

Note: Calibration does not function with PDF417 symbols. However, you can substitute a Code 128 symbol with the same mil size as your PDF417. When you do this, enable Code 128 and disable Raster scanning. After calibration, switch back to PDF417 and Raster scanning.

Usage: Used in applications where a large amount of information (over 32 characters) needs to be encoded within a symbol, typically where the symbol is transported from one facility to another. For example, an automobile assembly line might use a single symbol with multiple fields of information that will be read at several stations along the way, without reference to a database.

Definition: A two-dimensional, multi-row (3 to 90), continuous, variable length symbology that has high data capacity for storing up to 2700 numeric characters, 1,800 printable ASCII characters, or 1100 binary character per symbol. Each symbol character consists of 4 bars and 4 spaces in a 17-module structure.

PDF417 Status

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Raster Sweeps Before Decode Attempt (PDF417)

Usage: Might be useful in dynamic applications where symbols are close together and need to be decoded more quickly than the default setting allows.

Definition: Specifies the number of raster sweeps the scanner will execute on PDF symbols before decoding. A value of 0 effectively disables this feature, which allows the decoder to make a “best guess” as to when enough symbol words have been captured.

Serial Cmd:

Default: 0 (disabled)

Options: 0 to 4

Fixed Symbol Length Status (PDF417)

Usage: Used to increase data integrity by ensuring that only one symbol length will be accepted.

Definition: When enabled, the PDF symbol must contain the same number of characters as the symbol length setting before it can be considered a good decode. The scanner will ignore any symbol not having the specified length.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled

1 = Enabled

Fixed Symbol Length (PDF417)

Definition: Specifies the exact number of characters the scanner will recognize.

Serial Cmd:

Default: 10

Options: 1 to 2710

Note: Fixed Symbol Length Status must be enabled for Fixed Symbol Length to take effect.

Decode at End of Read (PDF417)

Definition: Allows the user to specify that the decoding of the PDF417 symbol take place after the requirements of End of Read Cycle have been satisfied. This means that the scanner will accumulate information about the PDF417 candidate symbol but will not attempt to error-correct or translate the information until the end of the read cycle.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled

1 = Enabled

Narrow Margins/Symbology ID

Usage: Used when the leading and trailing edges of the symbols are smaller than the standard margin or when other objects encroach into the margins. Definition: Allows the scanner to read symbols with quiet zones less than 8 times the width of the narrow bar element. The “quiet zone” is the space at the leading and trailing ends of a symbol. Each quiet zone can be as narrow as only five times the width of the narrow bar element when Narrow Margins is enabled.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Note: Do not use Narrow Margins with Large Intercharacter Gap enabled in Code 39 or Codabar.

Symbology ID

Usage: Used when the symbology type and how it's decoded needs to be known.

Definition: Symbology ID is an AIM standard prefix set of characters that identify the symbol type.

When enabled, the scanner analyzes and identifies the symbology and adds a three character identifying prefix to the data:

1. ] (close bracket character) indicating the presence of a symbology ID

2. A, C, E, I, L, Q, b, d, p, P, M A = Code 39, C = Code 128 or EAN-128, E = UPC/EAN,
   I = I-2/5, F = Codabar; G = Code 93, L = PDF417, a = Pharmacode,
   e = Composite/RSS, L = PDF417 and Micro PDF417

3. Modifier (see Explanation of Modifiers below)

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Explanation of Modifiers for Code 39, Codabar, and Interleaved 2/5

• For Code 39, Codabar and I–2/5, the modifier indicates Check Character and Check Character Output Status.
• For Code 39 only, Full ASCII needs to be enabled to see modifiers 4, 5, and 7.

Modifier Check Character	Check Character Output	Full ASCII conversion performed (Code 39 only)
0 Disabled N/A No
1 Enabled Enabled No
3 Enabled Disabled No
4 Disabled N/A Yes
5 Enabled Enabled Yes
7 Enabled Disabled Yes

Example:]A5 indicates a Code 39 symbol with Check Character and Check Character Output Status enabled and Full ASCII conversion performed.

Explanation of Modifiers for Other Symbologies

• For Code 128, a 1 indicates EAN-128; otherwise the modifier is a 0.
• For all other codes, the modifier is 0.

Background Color

Background Color

Usage: If the background is darker than the symbol, then enable black background. Typically the background is white; but on PCBs for example, they can be black.

Definition: Allows the user to choose which symbol background (white or black) the scanner can read.

Serial Cmd:

Default: White

Options: 0 = White 1 = Black

Autodiscriminate

Although Autodiscriminate is not a configuration command, but it is included here as a convenient tool for enabling most symbol types.

Usage: Commonly used for quick setup mode to detect symbol type. This is particularly useful for users who might be unfamiliar with their application's symbology.

Note: It does not alter individual fields such as Start/Stop, Fixed Length, etc. These need to be setup individually.

Definition: Enables all available symbology types except PDF417, UPC/EAN, and Pharmacode. The user may also individually disable/enable each symbology type.

Serial Cmd:

Default: Code 39 (only)

Options:

Enables all codes except noted above.

Enables Code 39 only

Enables Codabar only

Enables I 2/5 only

Note: If using an I 2/5 symbol, verify that the number of characters in the symbol being scanned matches the symbol length enabled for the I 2/5 symbol type (default is 10 and 6).

Symbol Data Output

Usage: Useful when the host needs symbol data only under certain conditions.

Definition: Defines the conditions under which decoded symbols are transmitted to the host.

Symbol Data Output Mode

Serial Cmd:

Default: Good Read

Options: 0 = Disabled

1 = Match

2 = Mismatch

3 = Good Read

Disabled

Usage: Disabled is useful when an application only needs to use the discrete outputs and can allow the scanner to do the decision-making. When set to Disabled, the host does not need the symbol data and the communication lines are used only for setup and status checks.

Definition: When set to Disabled, the scanner will not transmit any data that is generated during a read cycle (symbols, No Reads, etc.).

Match

Usage: Match is typically used to route items with the same identifying data to the same location.

Definition: With Match enabled, the scanner transmits symbol data whenever the symbol data information matches the master symbol.

Mismatch

Usage: Mismatch is typically used as a flag within the host system to prevent an item from being routed in the wrong container.

Definition: With Mismatch enabled, the scanner transmits symbol data whenever the symbol data information does NOT match the master symbol.

Note: A No Read can still be transmitted if enabled.

Good Read

Usage: Good Read is used when an application requires all symbol data to be transmitted. It's typically used in tracking applications in which each object is uniquely identified.

Definition: With Good Read enabled, the scanner transmits symbol data on any good read regardless of Matchcode Type setting.

Note: A No Read can still be transmitted if enabled.

When to Output Symbol Data

Definition: This command allows the user to choose when symbol data can be sent to the host.

Serial Cmd:

Default: As Soon As Possible

Options: 0 = As Soon As Possible 1 = End of Read Cycle

As Soon As Possible

Usage: As Soon As Possible is useful in applications in which symbol data needs to be moved quickly to the host, typically when the host is making decisions based on symbol data.

Definition: Enabling As Soon As Possible causes symbol data to be sent to the host immediately after a symbol has been successfully decoded.

Note: More than one decode might in fact be required to qualify as a good decode, depending on how Decodes Before Output is set.

End of Read Cycle

Note: See End of Read Cycle Mode on page 4-14 for options to end the read cycle.

Usage: End of Read Cycle is useful in timing-based systems in which the host is not ready to accept data at the time it is decoded.

Definition: Enabling End of Read Cycle means that symbol data does not get sent to the host until the read cycle ends with a timeout or new trigger.

Read Cycle

No Read Message

No Read Message

Usage: Used in applications where the host needs serial verification that a symbol has not been read and especially useful in new print verification.

Definition: When enabled, and if no symbol has been decoded before timeout or the end of the read cycle, the No Read message will be transmitted to the host.

No Read Status

Serial Cmd:

Default: Enabled

Options: 0 = Disabled 1 = Enabled

No Read Message

Definition: Any combination of ASCII characters can be defined as the No Read message.

Serial Cmd:

Default: NOREAD

Options: 1 to 128 ASCII characters.

Note: No Read Message will only be transmitted if Symbol Output is set to Match, Mismatch or Good Read.

No Read Message can be set to any ASCII characters except NUL, <, >, and , .

Bad Symbol Message

Usage: Useful in determining if a symbol is present and if user defined requirements for that symbol are met. Can tell the user if a qualified symbol is present but not decodable.

Definition: Sets the requirements that will qualify an object or a symbol before outputting a decode or message. When enabled, sends a message to the host whenever an object meets the qualifications setup but is not decoded.

Serial Cmd:

Default: BAD_SYMBOL

Options: 1 to 128 ASCII characters

No Symbol Message

Usage: Useful in determining if a symbol is present and if user defined requirements for that symbol are met. Can tell the user if an object does not qualify as a symbol.

Definition: Sets the requirements that will qualify an object or a symbol before outputting a decode or message. When enabled, sends a message to the host whenever an object meets the qualifications setup but is not decoded.

Serial Cmd:

Default: NO_SYMBOL

Options: 1 to 128 ASCII characters

Read Duration Output

Usage: Useful in evaluating actual read cycle timing results, especially when initially setting up an application to determine maximum line speed (obtainable based on spacing between symbols.)

Definition: When enabled the duration of the read cycle (in milliseconds) is appended to the symbol data. The read duration is the time from the beginning of the read cycle until data is output.

Read Duration Output Mode

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Important: To measure the entire read cycle when in External Level trigger mode, set When to Output Symbol Data to End of Read Cycle.

This output can measure over 49 days' worth of duration; if exceeded, the "OVERFLOW" message will be output in place of the duration.

Read Duration Output Separator

Definition: User defined character that separates the symbol information from the Read Duration Output.

Serial Cmd:

Default: , (comma)

Options: Any ASCII character.

Output Indicators

Note: System features such as autocalibration and EZ Button setup may illuminate scanner LEDs regardless of parameter settings.

Green Flash Mode

Usage: Used as a visual verification that a Good Read has occurred.

Definition: An array of green LEDs in the front of the scanner can be programmed to flash in response to user-defined conditions.

Serial Cmd:

Default: Good Read

Options: 0 = Disabled

1 = Good Read

2 = Static Presentation

3 = Match

4 = Mismatch

Disabled

Green flash LEDs are disabled.

Good Read

Green flash LEDs will flash when a Good Read condition is met or when Matchcode is enabled and a match occurs.

Static Presentation Mode

Static Presentation Mode is used in conjunction with Continuous Read Mode: .

When operating in Static Presentation Mode, the red LEDs will illuminate while the scanner is searching for a symbol in Continuous Read Mode. When a symbol is placed in the field of view and a Good Read occurs, the green LEDs will illuminate and stay on for the duration of time set in Green Flash Duration. Only one read will occur during that time unless more than one symbol is enabled in Number of Symbols.

Note: If Static Presentation Mode is selected but the scanner is not in Continuous Read, the Green Flash will not occur.

To use Static Presentation:

1. Enable Continuous Read.
2. Select the number of symbols.
3. Enable Static Presentation in Green Flash Mode.
4. Select the read time in Green Flash Duration.

Output Indicators

Match

The green LEDs will flash when a match condition is met. If multisymbol is enabled, then green flash LEDs will illuminate only if all symbols qualify as a match. If matchcode is disabled, then this mode will activate the LEDs on a Good Read.

Mismatch

Same as Match, except that LEDs will illuminate on a mismatch.

Green Flash Duration

Usage: Provides visual verification that a Good Read has occurred.

Definition: When a Good Read occurs, the green LEDs will illuminate and stay on for the time set in the Green Flash Duration value.

Serial Cmd:

Default: 100 (1 second)

Options: 0 to 65535 (in 10 ms increments)

Beeper

Beeper

Usage: Can be used as an audible verification that either a good read or a No Read has occurred.

Definition: A beep is emitted either after each good read of a symbol or after each No Read.

Note: Beeper will also sound if any of the following occur:

• The scanner is defaulted.
• A send/save command from ESP or an Exit command from any embedded menu.
• A , , , or command is sent.

Beeper Status

Serial Cmd:

Default: On Good Read

Options: 0 = Disabled

1 = On Good Read

2 = On No Read

Serial Verification

Usage:

These commands are useful in removing any doubt about the scanner's acceptance and response to host configuration commands.

For example, if the current preamble is "SOM" and is entered, the scanner will echo back since the attempted entry "START" exceeds the four character limit for that command. Therefore it is rejected and the existing "SOM" message is echoed back and remains the preamble message.

Definition: Allows the user to verify configuration command status.

Serial Command Echo Status

Important Note: ESP will not function whenever this command is enabled.

Definition: When enabled, a configuration command received from the host is echoed back to the host with the resultant settings.

graph LR
    A["Host"] <--> B["Scanner"]

Function: If a command with multiple fields is processed, some of the fields may have been processed properly while others were not. The changes will appear in the string echoed back so that the user will know which fields did or did not change.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Serial Command Beep Status

Important: ESP will not function whenever this command is enabled.

Usage: Used to audibly verify the acceptance and validity of a command.

Definition: Causes the scanner to beep once whenever a K command is entered to indicate that the command was accepted and processed.

Function: If an invalid command is entered, the scanner beeps 5 times to indicate an invalid entry. However, this does not necessarily mean that all data fields have been entered incorrectly. Only one bad field needs to be found in order to activate the 5 beep response.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Serial Verification

Control/Hex Output

Usage: Useful for viewing settings with binary characters when using serial command on a terminal.

Definition: Determines the response to a Serial Command Echo or status request command.

When set to Control, two characters are transmitted to represent a non-displayable character. For example, a carriage return will be shown as the two characters: ^M.

When set to Hex, the output is the hex character.

Serial Cmd:

Default: Control

Options: 0 = Control 1 = Hex

EZ Button

The EZ Button has four positions, selectable by the length of time the button is held down, and indicated by one, two, three, and four beeps in succession. Each position can be programmed for any of eight options.

Definition: Serves as a master switch to enable/disable the EZ Button status.

Serial Cmd:

Default: Enabled

Options: 0 = Disabled 1 = Enabled 2 = Trigger

3 = Unlatch Outputs 4 = Parameter Switch

Global Status

Disabled

When set to Disabled, the EZ Button does not function.

Enabled

When selected, the EZ Button is enabled and the function of each button position is selected by the EZ Button Mode command.

Trigger

When selected, the EZ Button acts as a trigger for the scanner to start and end read cycles. All other button operations are inactive.

In External Level: The read cycle endures for as long as the EZ Button is pressed, unless a timeout occurs and Timeout is enabled for End of Read Cycle.

In External Edge: As with Level, Edge allows a read cycle to be initiated by pressing the EZ Button, but unlike Level, the read cycle ends with a Good Read output, a timeout, or a new trigger.

Unlatch Outputs

In this configuration, the EZ Button will unlatch any logic outputs that have been latched.

Parameter Switch

The parameter switch toggles between custom defaults and power-on settings. The condition is the same as that achieved by sending the and commands consecutively.

EZ Button

Default on Power-On

Definition: When enabled, if the EZ Button is held down on power-on the scanner will default and save for power-on.

Serial Cmd:

Default: Enabled

Options: 0 = Disabled 1 = Enabled

Load Configuration Database

Definition: Allows the user to load the Configuration Database with calibration results. When the user performs a calibration using the EZ Button, all the database entries are moved down one index and the results of the calibration are saved to index 1. The results will be saved as current settings as well.

Serial Cmd:

Default: Enabled

Options: 0 = Disabled 1 = Enabled

Save for Power-On

Definition: If enabled, after calibration is complete, all parameters will be saved for power-on.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

EZ Button Modes

Usage: Useful for performing multiple, repetitive tasks at the work site.

Definition: Allows the user to program each of the EZ Button's 3 positions from a selection of 10 modes.

Serial Cmd:

Options:

Single Beep Two Beeps Three Beeps
0 = Disabled 0 = Disabled 0 = Disabled
1 = Read Rate 1 = Read Rate 1 = Read Rate
2 = Calibration 2 = Calibration 2 = Calibration
3 = Save for Power-On 3 = Save for Power-On 3 = Save for Power-On
5 = Load New Master 5 = Load New Master 5 = Load New Master
9 = Bar Code Configuration 9 = Bar Code Configuration 9 = Bar Code Configuration

Disabled

When set to disabled, the associated button position will have no function associated with it, and the position will be skipped over.

Read Rate

Read Rate will be initiated when the associated button position is selected. Read Rate will perform decodes/second and is the same as sending a from the terminal. To exit Read Rate Mode quickly press and release the EZ Button.

Calibration

Calibration will be initiated when the associated button position is selected. To abort calibration, quickly press and release the EZ Button.

Save for Power-On

All scanner settings will be saved to non-volatile memory to be recalled on power-on whenever the associated button position is selected. This is the same as sending a from the terminal.

Load New Master

Functions in the same way as new master pin input whenever the associated button position is selected. The new master pin's Consecutive Decode requirement holds true for this function.

Bar Code Configuration

Enables Bar Code Configuration mode whenever the associated button position is selected. When enabled, the scanner can accept configuration commands from symbols. To disable, quickly press and release the EZ Button.

EZ Button Modes

Input 1

Definition: A programmable, discrete input used to reset counters, outputs or control optoelectrical settings.

Usage: For example, an application is setup so that a mismatch stops the production line by using outputs in a latch mode. A push-button switch can be connected to the input pin so that when pressed, it unlatches the output, allowing the line to resume operations.

Input Mode

Definition: Determines the functionality of the input.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled

1 = Reset Counts

2 = Unlatch Output

Disabled

Definition: When set to Disabled, there is no effect on operation.

Reset Counts

Usage: Primarily used in test mode. Can also be used to reset counters daily.

Definition: When set to Reset Counts, a transition to the active state of the input will cause the scanner to reset the internal counters (See Counters on page 12-6).

Unlatch Output

Definition: This setting is used in combination with any of the three discrete outputs that are in Unlatch Mode 1. A transition to the active state will clear any of the three outputs that were previously latched.

Active State

Definition: Determines the function of the input pin.

Serial Cmd:

Default: Active Closed

Options: 0 = Active Open 1 = Active Closed

Note: If set to Match or Mismatch, Symbol Data Output Status will not take effect unless Matchcode Type is enabled and a master symbol is loaded into memory.

Configurable Output 1

Output On

Usage:	This option provides discrete signalling to host software to control external devices such as PLCs and relays. It is useful for routing, sorting, and to prevent mis-packaging and mis-routing.
Definition:	Sets the discrete output functions for specific user-selected conditions. Allows the user to set the conditions under which an output (or outputs) will be activated.

Serial Cmd:

Default: Mismatch or No Read

Options: 0 = Mismatch or No Read

1 = Match or Good Read

2 = Mismatch

3 = No Read

4 = Trend Analysis

5 = [reserved]

6 = Diagnostic Warning

7 = In Read Cycle

Note: If Output On is set to Mismatch/No Read or Match/Good Read, a transition (switching) will not occur unless Matchcode Type is enabled and a master symbol is loaded into memory.

Mismatch or No Read

Activates a discrete output when the data does not match that of the master symbol or the symbol has not been decoded before the end of the read cycle.

Match or Good Read

Activates a discrete output when the symbol data matches the master symbol.

Note: If you want to output for a Good Read and Matchcode is not enabled, you can enable any output for Match.

Mismatch

Activates a discrete output whenever the symbol data does not match that of the master symbol.

No Read

Activates a discrete output whenever the symbol data is not decoded before the end of the read cycle.

Trend Analysis

Activates discrete output when a trend analysis condition is met, depending on the trend analysis option enabled.

Typically used when successful decodes are occurring but a discrete output is needed to flag a trend in quality issues.

Diagnostic Warning

Activates discrete output when a diagnostic warning condition is met, depending on the diagnostic option enabled.

Typically used when a discrete indication of a diagnostic condition is needed.

In Read Cycle

Activates a discrete output when the scanner is in a read cycle.

Configurable Output 1

Output State

Definition: Sets the active electrical state of the discrete output.

Serial Cmd:

Default: Negative

Options: 0 = Negative 1 = Positive

Pulse Width

Definition: Sets the time in 10 ms increments that the discrete output remains active.

Serial Cmd:

Default: 50

Options: 1 to 65535 (Divide the number entered on the command line by 100 for time in seconds)

Output Mode

Definition: Sets the condition in which the discrete output is de-activated.

Serial Cmd:

Default: Pulse

Options: 0 = Pulse

1 = Latch Mode 1

2 = Latch Mode 2

3 = Latch Mode 3

Pulse

This is the default mode of operation in which the programmable output is activated when the Output On condition has been met and held active for the duration of the selected pulse width.

Latch Mode 1 (Unlatch on Input 1 Pin)

In this mode the programmable output will be activated when the Output On condition is met. It will stay active until the state of the Input 1 pin changes from inactive to active or the proper mode is configured using the EZ Button.

Important: To unlatch using the Input 1 pin, the input status must be set to "Unlatch Outputs". To unlatch using the EZ Button, the button status must be set to Unlatch Mode.

Latch Mode 2 (Unlatch Opposite Condition)

The programmable output is activated when the Output On condition has been met and held active until the opposite condition selected under Output On has been met.

For example, if No Read is enabled under Output On, the programmable output will go active on a No Read and remain active until the opposite condition, a Good Read, occurs.

Latch Mode 3 (Unlatch Re-Enter Read Cycle)

The programmable output is active when the Output On condition has been met and is held active until a new read cycle begins.

Note: All of the Output On modes are inhibited when any Output on Warning is active for Output 1.

Trend Analysis Output 1

Note: Output On in Output 1 Parameters must be set to Trend Analysis for this output to function.

Usage: Useful in cases where the user doesn't want to shut down for one condition but wants to monitor quality and read conditions.

Definition: Applies Trend Analysis settings to Output 1.

With Trend Analysis, the user can track the occurrences and frequency of mismatches, No Reads, and the number of reads per trigger, and output the results to any of three outputs.

Example: Trend Analysis Mode = No Read

Number of Triggers = 25 triggers (read cycles)

Number to Output On = 4

Decodes per Trigger = 1

In this example, the scanner will activate an output when 4 No Reads occur within a period of 25 triggers (read cycles), at 1 decode per trigger.

Trend Analysis Mode

Definition: Sets the trend condition (Mismatch, No Read, Decodes/Trigger, Bad Symbol, or No Symbol) that will activate the output.

Serial Cmd:

Default: No Read

Options: 0 = Mismatch

1 = No Read

2 = Decodes/Trigger Threshold

3 = Bad Symbol

4 = No Symbol

Mismatch

Output will be activated when the number of mismatches equals the value entered for Number to Output On within the trigger window selected in Number of Triggers.

No Read

Output will be activated when the number of No Reads equals the value entered for Number to Output On within the trigger window selected in Number of Triggers.

Decodes/Trigger Threshold

Output will be activated when the number of decodes equals the value entered for Number to Output On within the trigger window selected in Number of Triggers.

Bad Symbol

Output will be activated when the number of Bad Symbol occurrences equals the value entered for Number to Output On within the trigger window selected in Number of Triggers.

No Symbol

Output will be activated when the number of No Symbol occurrences equals the value entered for Number to Output On within the trigger window selected in Number of Triggers.

Configurable Output 1

Number of Triggers

Definition: The number of triggers to examine for the trend analysis condition.

Serial Cmd:

Default: 0

Options: 0 to 255

Number to Output On

Usage: Example: If Number to Output On is set to 3 and Trend Analysis Mode is set to No Read, then the output will not be activated until 3 No Reads have occurred.

Definition: Sets the number of Trend Analysis Mode events (mismatches, No Reads, or reads/trigger as configured by Trend Analysis Mode) to occur within the trigger evaluation period before activating the associated output.

Serial Cmd:

Default: 0

Options: 0 to 255

Decodes/Trigger Threshold

Definition: When set to this mode, and when the appropriate output is set to output on trend analysis, the scanner will function in a Decodes per Trigger mode during the read cycle and the trend analysis operation. Output will be activated based on whether or not the symbol decode count at the end of the read cycle crosses the decodes per trigger threshold.

Note: Although this setup causes the scanner to function in a Decodes per Trigger mode, the decode count will only be appended to the symbol data if the status of the Decodes per Trigger command is enabled.

Serial Cmd:

Default: 0

Options: 0 to 65535

Diagnostics Output 1

Note: Output On in Output 1 Parameters must be set to Diagnostic Warning for this output to function.

Database Identifier Output

Usage: Useful in keeping track of which database entries read which symbols.

Serial Cmd:

Default: 0

Options: 0 = Disabled 1 = Enabled

Output Status

Disabled

When this command is disabled, no database identifier information will be output.

Enabled

When this command is enabled, the scanner will append a two-digit number and the characters "DB" to the data output following the separator for each symbol decoded using Configuration Database. For example, if the separator is an underscore character and the second database entry reads a symbol encoded with "data capture" during the read cycle, the symbol data output will be "data capture_DB02". If the database is not active, no identifiers will be attached to output.

Separator

Usage: The separator character separates the symbol data from the database identifier.

Serial Cmd:

Default:

Options: Any ASCII character

Quality Output

Definition: Allows the host to track the number of good reads per trigger by appending a five digit numeric field to the end of symbol data.

When enabled, symbol data is followed by a separator, followed by the five digits in the form of 00000. For example, a certain symbol that has been averaging 00100 decodes per read cycle suddenly drops to 00012, this would be a good indication that a problem has arisen even though good reads are still occurring.

Usage: Host system can monitor scanning performance (printing process, scanning environment changes, etc.) by setting thresholds in their processing or displaying the outputs for visual verification.

Overview of Matchcode

Usage:

Matchcode is used in applications to sort, route, or verify data based on matching the specific symbol in a variety of ways, as defined in this section. For example, a manufacturer might sort a product based on dates that are embedded in the symbol.

Definition:

With Matchcode you can store master symbol data in the scanner's memory, compare this data against the scanned symbols, and define how symbol data and/or discrete signal output will be directed. A master symbol database can be set up for up to 10 master symbols.

Using Master Symbols

1. Set Triggering Mode to External or Serial (see Trigger on page 4-5).
2. Set Matchcode Type to an option that fits your application (see Matchcode Type on page 7-5).
3. Define the output you want with your matchcode setup:
   a) Data output (Symbol Data Output on page 6-4).
   b) Discrete output (see Configurable Output 1 on page 6-20).
4. Select the number of master symbols you want to create. If more than one, send a command (see Master Database on page 12-11).
5. Enter master symbol data in one of the following ways:
   a) Use ESP to type in master symbol data directly into the Utilities menu.
   b) Send a serial command with symbol data in the form of (or <) data> for single master symbol only).
   c) Send a command to scan the next symbol as the master symbol.
   d) Enable the New Master Pin command and activate a discrete input to store the next symbol scanned as the master symbol (see New Master Pin on page 7-11).

Matchcode Type

Note: When Matchcode is set to Enabled, Wild Card or Sequential, Number of Symbols will default back to 1 (if set to any number greater than 1).

Definition: Allows the user to choose the way that master symbols will be compared with subsequently scanned symbols.

Note: First set Triggering Mode to External or Serial.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled

1 = Enabled

2 = Sequential

3 = Wild Card

Disabled: Has no effect on operations.

Enabled: Instructs the scanner to compare symbols or portions of symbols with the master symbol.

Sequential Matching: Instructs the scanner to sequence after each match (numeric only) and compare symbols or portions of symbols for sequential numbers.

Note: If Matchcode Type is set to Sequential, Number of Symbols will default back to 1 (if set to any number greater than 1).

Wild Card: Allows the user to enter user defined wild card characters in the master symbol.

Sequential Matching

Usage: Used in tracking product serial numbers that increment or decrement sequentially.

Definition: With Sequential enabled under Matchcode Type, Sequential Matching determines if a count is in ascending (incremental) or descending (decremental) order.

Serial Cmd:

Default: Increment

Options: 0 = Increment 1 = Decrement

Matchcode Type

Match Start Position

Usage: Match Start Position is useful in defining specific portions of a symbol for comparisons. For example, if a symbol contains a part number, manufacturing date, and lot code info but the user is only interested in the part number information, Match Start Position can be set to only sort on the part number and ignore the rest of the characters.

Definition: Match Start Position determines the portions of symbols that will be matched by defining the first character in the symbol (from left to right) that will be compared with those of the master symbol, when Matchcode Type is set to Enabled or Sequential.

Function: For example, if Match Start Position is set to 3, the first 2 characters read in the symbol will be ignored and only the 3rd and subsequent characters to the right will be compared, up to the number of characters specified by Match Length.

Serial Cmd:

Default: 0

Options: 0 to maximum length allowed for master symbol

Note: Match Start Position must be set to 1 or greater to enable this feature. A 0 setting will disable this feature.

Match Length

Definition: Defines the length of the character string that will be compared with that of the master symbol when Match Start Position is set to 1 or greater. When Match Start Position is set to 0, no comparison will occur.

Usage: For example, if Match Length is set to 6 in a 10 character symbol, and Match Start Position is set for 2, only the 2nd through 7th characters (from left to right) will be compared.

Serial Cmd:

Default: 1

Options: 1 to 2710

Wild Card Character

Usage: For example, with Wild Card Character defined as the default asterisk, defining CR*34 as the master symbol will result in matches for CR134, CR234, but not CR2345. Entering the wild card at the end of the master symbol as in CR*** will result in matches for variable symbol lengths such as CR1, CR23, CR358, etc. provided that the number of wild card characters matches or exceeds the number of characters present.

Definition: Wild Card Character allows a user to define a wild card character as part of the master symbol.

Serial Cmd:

Default: * (asterisk)

Options: Any valid ASCII character

Matchcode Type

Sequence On No Read

Usage: Sequence On No Read is useful when the scanner needs to stay in sequence even if no decode occurs.

Definition: When Sequence On No Read is Enabled and Matchcode is set to Sequential, the scanner sequences the master symbol on every match or No Read. When disabled, it does not sequence on a No Read.

Serial Cmd:

Default: Enabled

Options: 0 = Disabled 1 = Enabled

As an example of Sequence on No Read Enabled, consider the following series of decodes:

Master symbol Decoded symbol Master symbol after decode
001 001 002
002 002 003
003 No Read 004 (sequenced on No Read)
004 004 005
005 No Read 006 (sequenced on No Read)
006 No Read 007 (sequenced on No Read)
007 007 008

As an example of Sequence on No Read Disabled, consider the following series of decodes:

Master symbol Decoded symbol Master symbol after decode
001 001 002
002 002 003
003 No Read	003 (not sequenced)
003 003 004
004 No Read	004 (not sequenced)
004 No Read	004 (not sequenced)
004 004 005

Sequence On Mismatch

Note: Matchcode must be set to Sequential for this command to function.

Usage: Enable this parameter if every trigger event should have a decode and more than one consecutive mismatch may occur. Disable this parameter if every trigger event should have a decode but no more than one consecutive mismatch may occur.

Definition: When set to Enabled, the master symbol sequences on every decode, match or mismatch.

When set to Disabled, the master symbol will not sequence whenever consecutive mismatches occur.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

The scanner will sequence the master to one more/less than the decoded symbol. As an example of Sequence On Mismatch Enabled, consider the following decodes:

Master symbol	Decoded symbol Master	symbol after decode
001 001 002
002 002 003
003 abc 004	(sequenced on mismatch)
004 004 005
005 def	006 (sequenced	on mismatch)
006 ghi	007 (sequenced	on mismatch)
007 007 008

As an example of Sequence On Mismatch Disabled, consider the following decodes:

Master symbol	Decoded symbol	Master symbol after decode
001	001	002
002	002	003
003	abc	004 (sequenced because of previous match)
004	004	005
005	def 005 (sequenced because of previous match)
005 ghi 005	(not sequenced because of previous mismatch)
005	005	006

You can access Master Symbol operations from the Utilities menu.

Sequence Step

Sequence Step

Usage: Useful in applications in which it is desirable to count by intervals other than 1.

Definition: Sequencing in Matchcode operations can occur in steps from 1 to 32,768.

Sequencing performs like a mechanical counter by displaying positive integers and a specific number of digits after rollovers.

For example, 000 - 3 = 997 (not -3) and 999 + 3 = 002 (not 1002).

Serial Cmd:

Default: 1

Options: 1 to 32768

Note: See (Matchcode Type on page 7-5) for more information.

As an example of Sequence Step, if Sequence Step is set to 3 and Sequential Matching is set to Increment.

Master Symbol Decoded	Symbol Master Symbol After Decode
003 001 003
003 002 003
003 003 006
006 004 006
006 005 006
006 006 009

New Master Pin

Usage: Some applications require the line worker to change the master symbol. This can be done by installing a switch at the location of the scanner. It is very common to have a keyed switch so that accidental switching does not occur.

Definition: After New Master Pin is enabled, a pulse can be received on the new master pin which will cause the scanner to record the next decoded symbol(s) as the new master symbol(s).

It is important to note that the enabling New Master Pin does not in itself cause a master symbol to be recorded. The master pin must then be activated momentarily (for a minimum of 10 ms) before a master symbol can be scanned into memory.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

After New Master Pin has been enabled and the pin activated, decodes will be saved in the master database beginning with master symbol #1. If the scanner is configured for a multisymbol read cycle (Number of Symbols is greater than 1), the remaining decodes will be saved in each consecutive master symbol location. For example, if Number of Symbols is set to 3 and New Master Pin is then activated, at the end of the next read cycle, the decoded symbols will be saved as master symbols 1, 2, and 3.

Match Replace

Usage: Provides a convenient shortcut for applications that need to output a predefined text string whenever a symbol matches a master symbol.

Definition: Outputs a user-defined data string whenever a match occurs and Matchcode is enabled.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Replacement String

Definition: User-defined data string that, when enabled, replaces symbol data whenever a match occurs.

Serial Cmd:

Default: MATCH

Options: 1 to 128 ASCII characters

Mismatch Replace

Usage: Provides a convenient shortcut for applications that need to output a predefined text string whenever a symbol does not match a master symbol.

Definition: Outputs a user-defined data string whenever a mismatch occurs and Matchcode is enabled.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Replacement String

Definition: User-defined data string that, when enabled, replaces symbol data whenever a mismatch occurs.

Serial Cmd:

Default: MISMATCH

Options: 1 to 128 ASCII characters

The purpose of calibration is to optimize the scanner's optical settings (focus, gain, and tracking) and scan speed to obtain the highest read rates in one or several symbol positions as required by the user's application. This section includes the overall steps in calibration and specific steps for calibration by ESP, serial command, and embedded menus. For most applications calibration is the only optical setup required.

Changes to motor speed, focus, speed, gain, tracking, and AGC can also be made individually by manual command.

Calibration Methods

There are three ways to initiate calibration:

• ESP Calibration menu
• Serial command <@CAL>
• Embedded menu <@>

Note: Calibration does not function with PDF417 symbols. However, you can substitute a Code 128 symbol with the same mil size as your PDF417. When you do this, enable Code 128 and disable Raster scanning. After calibration, switch back to PDF417 and Raster scanning.

Calibration Steps

Follow this procedure for all three methods of calibration:

1. Position your symbol at the distance used in your application and confirm that it is at a distance within the specifications for that symbol size (see Position Scanner and Symbol on page 1-5).
2. If you are not certain of the code type, enable all code types by sending a

   command from the terminal window, or clicking on the Autodiscrimination button in Calibration/Advanced in ESP.

3. Start the calibration procedure.

Note: Once a successful calibration is completed, you may want to save the setting to the calibration database (see Configuration Database on page 9-6).

1. Repeat calibration at other ranges and/or symbol types you might be scanning in your application.

2. Check your readings at each end of the scan width required for your application, keeping in mind that the scan width testing may not produce results that are entirely symmetrical.

Note: If you are setting up for laser framing, be sure that you only test for calibration in the active areas of the scan beam.

1. To save the new settings (including focus, gain, and tracking) for power-on, use the Send/Recv button or send a command.

Diagram showing two devices connected by a dashed line, with a vertical red line and a rectangular panel on the left (no text or symbols)

See Configuration Database on page 9-6 to learn how to setup a database using calibration or manually specified values.

See Advanced Calibration Features on page 9-14 for ways to speed up and improve your calibration process.

Note: To silence the beeper, send or remove or block the test symbol.

Calibration Routine

To calibrate gain, tracking, focus position, and scan speed automatically:

1. Click the Calibration button near the top of the screen.

1. Click the Calibrate button to start calibration.

A "Calibration in Progress..." message will be displayed on your monitor along with the pass number and information on the focus position, gain, tracking and read rate.

Allow some time for the scanner to cycle through the settings. Do not move or disturb the scanner or symbol while calibration is in progress. (It might take 2 to 3 minutes to complete.)

1. When completed, the settings that provided the highest read rate will be selected. You will see one of the following messages: "Calibration Passed" or "Calibration Failed". If calibration passed, you will continue to see the read rate percentage and symbol data in the open pane below the data.

Calibration by Serial Command

To start the calibration process by serial command, send <@CAL> from ESP's Terminal.

Calibration Results

When a calibration command is sent, the scanner first steps through a coarse grid of focus settings, looking for readable symbols, and recording the highest read rates it encounters. This is Pass 1. During Pass 2, the scanner returns to the focus position where it found the best read rate and steps through a finer grid of focus, gain and tracking settings. The software evaluates the results and selects the best data. If calibration passes, a “Calibration Passed” message is displayed at the top of the window.

To load the settings obtained from calibration into the Configuration Database:

1. Perform the calibration routine described in Calibration Routine on page 9-4.
2. Click on the Configuration Database tab.
3. Set Number of Active Database Settings and make your selection in Optoelectric Control in the menu tree to the left of the Database tab.
4. Click on an index to load standard settings.
5. Click Load Standard Settings to Database button.
   This will put Focus, Gain, and Tracking settings that resulted from calibration into the database index.
6. Repeat this procedure for other indexes.

You can also enter individual values in any of the seven indexes by double-clicking anywhere on the index row and making changes in the popup text box.

Configuration Database

Configuration Database by Serial Command

Note: You can also set Focus, Gain Settings, Tracking Adjustment, Scan Speed, Laser Framing, and Background Color individually.

Definition:

The Configuration Database allows the user to save multiple scanner configuration settings. The database can be used to save the most commonly used configurations, making the scanner easily adaptable to changing applications, or it can be used in conjunction with Optoelectric Control, to change configurations dynamically.

When Optoelectric Control is set to Control Trigger (Optoelectric Control Mode), the first seven indexes can be switched by external inputs. Each database configuration setting is assigned to a control trigger sequence.

The table below illustrates the relationship between control trigger sequence and database indexes.

I	Active Trigger(s) = 1, 2, 3			Active Trigger(s) = 1, 2 A			Active Trigger(s) = 1
	Control Triggers Control			Triggers Control Triggers
	n	d	e	x	3	2	1	3	2
10	0	1		0	0	0	1	/	0
20	1	0		1	1		N
30	1	1		1	0		Disabled		A
41	0	0		Disabled	1				A
5101	N/A	N/A	N/A
6110	N/A	N/A	N/A
7111	N/A	N/A	N/A

0 = Inactive Input State

1 = Active Input State

Serial Cmd:

Important: Control Trigger 3 uses the External Trigger input. When this input is active, there is no external trigger available to the scanner. Therefore, when Control Trigger 3 is active and External Trigger Mode is selected, a read cycle will be triggered by an active input from any of the control trigger inputs.

Since an active state on one of the control inputs is required to trigger a read cycle, sequence "000" would not be valid. When Control Trigger 3 is active, the sequence starts at "001". This allows a maximum of 7 accessible database settings. When Control Trigger 3 is not active, the sequence starts with all active inputs disabled.

Optoelectric Control

Note: Optoelectric Control requires the assembly of a Configuration Database.

Optoelectric Control Mode

Usage: Useful where different symbol types, sizes, qualities or distances require more that one optical setup (focus, gain, and tracking) for dynamic optical changes.
Definition: A database index of up to seven pre-defined optical indexes of settings defining focus, gain, and tracking can be accessed and applied in the following modes:
- A timer in which all settings cycle throughout the time duration.
- An automatic search for the best database index.
- A combination of up to three control trigger inputs to dynamically select the optimum database index.
The index settings can also be saved and recalled selectively, or reviewed with a Request Database Settings command.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled

1 = Control Trigger
2 = Automatic/Static Mode

4 = Number of Raster Sweeps

Disabled

Definition: When disabled, the scanner uses the standard configuration settings that are set in the Calibration tree and shown to the right of Standard in the Database Index.

Serial Cmd:

Control Trigger (Optoelectric Control Mode)

Usage:

Useful where different symbol types, sizes, and/or distances benefit from pre-defined optical setups (focus, gain, and tracking) that can be accessed 'on the fly' according to the combination of input states.

Definition:

When Optoelectric Control mode is set to Control Trigger, input 1, new master pin, and the trigger input pins are de-activated and re-assigned as control triggers. When activated, a read cycle will be triggered and—in accordance with their respective states—selected from a database of up to seven pre-defined optical settings of Focus, Gain, and Tracking. (See Configuration Database on page 9-6)

Serial Cmd:

Using Control Trigger

Set up your application's symbols by symbology type/size in the various positions and/or code type/size at which they will likely appear.

Set up your sensors or other controls. For example, the three object sensors, 1, 2 and 3, are connected to input 1, new master pin, and trigger input respectively. The bar-coded packages on the left are numbered here according to their database index numbers. Package #7 will cross all three of the sensors and thus activate the settings for index #7.

In this scenario only four index settings are possible. However, up to seven combinations are possible with other input devices such as PLCs.

You can also enable/disable any combination controls by clicking on the Control Trigger Status buttons on the bottom of the Control Trigger Map. The red buttons indicate active states on the three control triggers. The combination of active/inactive triggers determines the focus, gain, and tracking settings that will be applied during a read cycle. For example, if only Control Trigger 1 is active, the focus, gain, and tracking values that appear in the top row will be applied.

Optoelectric Control

Automatic/Static (Optoelectric Control Mode)

Usage: Useful in a static application in which the symbol is in front of the scanner when the read cycle begins.
Definition: Selects the optimum setting from the Configuration Database.
When selected, the scanner cycles once through all the Configuration Database settings from the closest to the furthermost focal position, testing first for optimal signal, then for a successful decode.
Note: Since focus positions are tested in ascending order, the closer the symbols are to the scanner, the quicker the best focus position will be found.
Important: The maximum time to move from the most inside focus position to the most outside focus position is 400 ms. One focus position change takes 10 ms.
Serial Cmd:

Timer Mode (Optoelectric Control Mode)

Usage: Useful in applications in which there is enough time to cycle through the database index.

Definition: When this mode is selected, the scanner cycles through database settings at a time interval determined in Timer Value setting. (See Timer/Switch Value on page 9-11.)

Important Note: The maximum time to move from the most inside focus position to the most outside focus position is 400 ms. One focus position change takes 10 ms.

Serial Cmd:

Note for Multisymbol: With Multisymbol enabled for more than one symbol, and either Timer or Automatic/Static mode enabled, the scanner may not locate symbols that are scanned at various ranges. The reason for this is that once a symbol is located from the optical database index, the scanner will continue to search for symbols that meet that index of focus, tracking and gain settings.

Number of Active Database Settings

Usage: Can be useful when certain settings that are needed for one application are not needed in another and processing time is at a premium.

Definition: This value sets the number of configuration database settings (in Database Index) that are active. If Control Trigger mode has been selected, this setting is ignored.

Serial Cmd:

Default: 1

Options: Any number from 1 to 7.

Latch on Trigger

Usage: Useful when only one database index is required for the application.

Definition: This feature is only used in Control Triggermode. If enabled, the configuration database settings selected at the start of a read cycle will remain active during the entire read cycle. If Latch on Trigger is disabled, depending on the control trigger inputs, the scanner's optical settings can change throughout the read cycle.

Note: When Control Trigger #3 is enabled, Latch on Trigger is also enabled regardless of its previous setting.

Serial Cmd:

Default: Enabled

Options: 0 = Disabled

1 = Enabled

Timer/Switch Value

Usage: Useful in slower applications where there is enough time to cycle through the database index.

Definition: When Timer mode is enabled, Timer Value is the time interval in which database index settings are cycled.

Serial Cmd:

Default: 5

Options: 0 to 255 (increments of 10ms)

Optoelectric Control

Control Trigger 1 Status

Definition: When Control Trigger mode is enabled, Control Trigger #1 takes over Input 1 (see Input Mode on page 6-19) and uses it to select an optoelectric configuration from the configuration database. Active state is set by Input 1 serial command.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Control Trigger 2 Status

Definition: New Master Pin is used for Control Trigger #2. When enabled and Mode is set to Control Trigger, this input is used to select an optoelectric configuration from Configuration Database. Active State is "Active Closed".

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Control Trigger 3 Status

Definition: Trigger Input is used for Control Trigger #3. When enabled and Mode is set to Control Trigger, this input is used to select an optoelectric configuration from the Configuration Database. Active State is set by the External Trigger State serial command.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Database Cycles

Definition: Database Cycles refers to the number of times the scanner will load the series of active entries when it is set to Timer or Raster Sweep modes. When set to 0, the scanner will cycle repeatedly through all active database entries until the read cycle ends. When set to a value greater than 0, the scanner will only load the active database entries for the defined number of times before staying with the last active entry for the remainder of the read cycle.

Serial Cmd:

Default: 0 Options: 0 to 255

Advanced Calibration Features

In the Advanced tab in the Calibration menu you can constrain the scan width of the scan beam with Laser Framing and set up the rules the scanner will follow during calibration procedure. See Laser Framing on page 10-7 for information on laser framing.

Auto Range

Usage: Enabling Auto Range improves focus acquisition speed where extraneous objects are not mistaken for symbols.

Definition: With Auto Range enabled, the scanner will focus outward and not begin the calibration routine until an object is detected by signal strength.

Serial Cmd:

Default: Enabled

Options: 0 = Disabled 1 = Enabled

Using Auto Range

1. Be sure there are no extraneous objects between the symbol and the scanner.
2. Click on the Advanced tab in the Calibration menu.
3. If Auto Range is not enabled, click on it to enable it.
4. Click the Calibrate button to start calibration.
5. Examining the read rates in the Results graph following calibration.

Starting Focus Position

Usage: Starting Focus Position can improve focus acquisition speed during calibration when the approximate range of the symbol is known.

Definition: With Auto Range enabled, the scanner will begin the calibration routine at the focal range set in Starting Focus Position.

Serial Cmd:

Default: 0

Options: 0 to 40

After you've used calibration and observed the progress of the first and second passes in the graph and table in the Results tab, you should sense a relationship between focus position and the distance to the symbol.

Improving the speed and accuracy of focus position setup:

1. Click on the Advanced tab in the Calibration menu.
2. If Auto Range is enabled, click on it to disable.
3. From previous results, estimate the value of Starting Focus Position and drop down one or two positions.

For example, if you estimate the distance to your symbol to correspond to a Starting Focus Position of 6, enter 5 or 4 to be certain of not missing the peak performance distance.

1. Click the Calibrate button to start calibration.
2. Examining the read rates in the Results graph following calibration.

Focus Step Size

Usage: Increasing the Focus Step Size can improve focus acquisition speed for symbols.

Definition: Focus Step Size is the number of focus increments that will be stepped through during the first calibration pass. The range is 2 to 5. The higher values will result in fewer readings during the first pass but will increase the risk of missing the peak performance position.

Serial Cmd:

Default: 5

Options: 2 to 5

Improving the speed and accuracy of focus step size setup:

1. Click on the Advanced tab in the Calibration menu.
2. If Auto Range is enabled, click on it to disable.
3. Enter a value in Focus Step Size.
4. Click the Calibrate button to start calibration.
5. Examine the read rates in the Results graph following calibration.

3. Wait for calibration to cycle through its settings.
   A Calibration in Progress message will be displayed. A new text line will appear below the menu displaying the progress of the calibration.
4. As with the serial command, repeat the routine at other positions in your scan range and width and save each position to the configuration database.
5. If not successful, a Calibration Failed message will be displayed. If successful, a Calibration Passed message will be displayed along with other settings.

Note: Focus positions Inside, Outside, and Set posted near the bottom of the above menu are explained more fully in Calibration Results in Embedded Menus on page 9-20.

Note: If you are using the 9-pin configuration port and doing calibration by serial command or embedded menus, you will be able to view decoded symbol data in the menu. However, after exiting the Calibration menu, you will not be able to see symbol data without sending the following command: . If using ESP, this is not necessary.

Scanner Settings by Embedded Menus

Motor Speed, Gain Setting, and Tracking adjustments affect the read performance.

Focus controls a stepper motor that physically slides a lens back and forth to control focal length. These settings are adjusted automatically in calibration.

The status of these parameters is displayed on the bottom line of the menu under Motor, Gain, Track, and Focus. These settings are incremented or decremented by pressing the indicated key shown on the menu. PDF417 Decode, AGC Status, Laser Power, and Raster Status use single commands to toggle between states.

AGC Status

Typing S toggles AGC between Enable/Disable, as displayed on a the status line near the bottom of the menu. With AGC disabled this value is simply the Gain setting. However, with AGC enabled, this value represents the gain the scanner has to set to maintain the desired signal amplitude. If a symbol is close to the scanner, the AGC level should be a small value because the scanner does not need much gain to achieve the desired signal amplitude. However, as a symbol gets farther away from the scanner, this value will increase to maintain the signal amplitude.

Laser Power

Typing L toggles between High and Low laser settings.

PDF417 Decode Test

Typing D toggles the PDF417 Decode Test between Enable/Disable, as displayed on a the status line near the bottom of the menu. Once set to Enabled, PDF417 only is enabled and a special test mode is enabled that displays the decodes per second of a full PDF417 symbol. While calibration is not performed in this mode, you can still adjust settings manually. This special read rate will remain enabled until the Calibration menu is exited or PDF417 is disabled with another D command.

Note: This mode averages decode and capture time over a series of readings, thus assuring for a smooth read rate output, but at the cost of delayed reaction to symbol movement and user setting changes.

Calibration Embedded Menu Options

START Calibration

Typing A initiates an calibration sequence. Once entered, no other keystrokes will be accepted with the exception of the ESC key, which terminates the routine.

RECALL Initial Settings

Typing B restores the original settings that were present upon entering the Calibration Setup Menu. These settings include Motor Speed, Gain, Tracking, and Focus.

SAVE Settings to Database

Typing C saves the current Gain, Tracking, and Focus settings to the Configuration Database. The database is made up of indexes 1 through 7. Current settings will be saved to the first open index.

EXIT Calibration Setup Menu

To exit the Calibration Setup menu, press the ESC key. The following prompt will be displayed: "Do you want to save calibration settings for power on? (Y=yes N=no)."

Typing Y will cause the current settings in the Calibration Setup menu to be saved to Flash Memory for recall when the scanner is powered up at a later date. These settings include Motor Speed, Gain, Tracking, Focus, AGC Status, Laser Power, and Raster Status. Typing N will cause the scanner to be reset without saving the settings to Flash memory.

FOCAL RANGE IN SET OUT

The Calibration Results menu shows the results of the calibration process for Read Rate, Gain, and Tracking for both the first and second passes. Note that the first pass has only one reading for each parameter.

Focus Positions

In the example above, the focus position selected from the first calibration pass (position 26) represents the optimal focus position for Read Rate, Gain, and Tracking. The second "fine tune" pass commences 3 focus positions in from this and steps out until the read rate drops off to zero.

Focal Range

The algorithm selects the best focus position (SET) as the midpoint between those positions (IN and OUT) at which read rates drop off by no more than 6-2/3 percent of the maximum read rate. For example, in the above menu, the read rate for focus position 24 is 73. Since 73 is more than 6-2/3% below the maximum read rate of 100% shown elsewhere, the IN range falls under the next focus position, 25. A mirrored calculation is performed to locate the OUT focal range.

Press the enter key (CR) to return to the main calibration menu or ESC to leave the Auto Calibration Setup menu entirely.

Advanced Calibration Setup Embedded Menu

The Calibration Setup menu allows you to change the starting focus position and the number of focus steps during the first pass.

For example, if you are preparing to do calibration on symbols whose minimum distances from the scanner is 40 inches, there is no reason for calibration to cycle through all of the focal positions inside 40 inches.

• To increase Starting Focus Position, type T. To decrease it, type R.
• To increase the First Pass Focus Step, type G. To decrease it, type F.

Increasing First Pass Focus Step will speed up the autofocus process, but can also cause autofocus to skip over a symbol and not decode it.

Note: All single letter commands must be entered in upper case.

• Auto Range is disabled by default. To enable, press A.

Raster Setup

You can set up and make changes to the scanner's raster parameters in ESP's Read Cycle, Calibration, or Raster/Laser views (preferred).

To access the Raster Setup menu, click the Raster/Laser button and the Raster Setup tab.

Usage:

Raster scanning is useful when symbols vary in placement and a single scan line cannot be counted on to cross the symbol, and for reading stacked symbologies such as PDF417.

Definition:

The user can enable raster scanning and adjust the raster sweep limits and the sweep rate.

Raster Setup | Laser Framing | Status Static Line Rastering Top Offset 127 Bottom Offset 255 Sweeps / sec 10 ✓ Raster on only during Read Cycle ✓ Laser on only during Read Cycle Send and Save Default Note: These buttons only affect this view.

Note: Changes made in the Raster Setup menu are dynamic; that is, they take effect without saving.

Raster Setup

Raster Status

Definition: When disabled, the raster mirror will park at the top of the raster sweep.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Note: Raster sweeps are only counted during a read cycle (continuous, triggered, and read rate). Raster sweeps are NOT counted when the raster motor is parked, disabled, set to straight line operation (top and bottom are equal), or when performing a self-calibration.

Top Offset

Definition: Decreasing the Top Offset value causes the top of the raster pattern to move up.

Serial Cmd:

Default: 127

Options: 0 to 255

Bottom Offset

Definition: Increasing the Bottom Offset value causes the bottom of the raster pattern to move down.

Serial Cmd:

Default: 127

Options: 0 to 255

Note: For single scan line operation, set Top Offset equal to Bottom Offset or click on the Static Line option.

Note: Assigning a larger value to Top Offset than Bottom Offset will park the raster mirror in its "home" (default) position.

Raster Sweep Rate

Usage: If your application allows it, a slower sweep rate can produce more scans per second and higher read rates. To determine the minimum read rate for your application, see Raster Picket Fence Calculation on page A-28.

Definition: The raster sweep rate is the number of sweeps per second the raster mirror completes. A sweep is one pass of the raster, up or down. The maximum sweep rate is limited by the size of the arc the raster must move through.

Serial Cmd:

Default: 10

Options: 0 to 30.

The table below shows the maximum speeds at selected raster sweep arcs. To maximize the number of scans per symbol, use the lowest effective sweep rate required for the application.

Raster Sweep Arc Maximum Sweeps per Second
0 to 10° 30
11 to 20° 20
21 to 36° 10

Raster Setup

Read Cycle On/Off

Usage: This feature should only be used when the raster sweep rate is at least twice the required trigger rate ( decoded outputs per second).

Definition: When Read Cycle On/Off is enabled and Laser On/Off is also enabled, the raster mirror stops at top offset at the end of triggered read cycle.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Laser Framing

To access the Laser Framing menu, click the Raster/Laser button and the Laser Framing tab.

Raster/Laser Raster Setup Laser Framing On Position 10 Framing Enabled Off Position 95 Laser on only during Read Cycle Send and Save Default Note: These buttons only affect this view.

Laser On/Off Status

Usage: Laser On/Off extends the life of the laser. It is useful where there are significant time gaps between symbols. It also provides visual confirmation of a read cycle timeout and minimizes laser exposure to people.

Definition: When enabled, the laser is ON only during the read cycle. When disabled, the laser operates continuously.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

Note: A serial or external trigger must be enabled for Laser On/Off to take effect.

Note: Laser On/Off is not recommended when New Trigger is enabled, since the laser will effectively remain on continuously.

Laser Framing

Laser Framing Status

Usage: Useful in avoiding highly reflective objects, for filtering out unwanted signals, or avoiding the wrong symbols.

Definition: Sets the length of time the laser is ON during each scan so that only a selected portion of the scan width is effectively scanned.

Serial Cmd:

Default: Disabled

Options: 0 = Disabled 1 = Enabled

To adjust laser framing, click the Raster button, click the Laser Setup tab, and click the Laser On and Laser Off arrows up or down.

When Laser Framing is not enabled, the scan beam sweeps across the full scan width. When enabled, the laser remains OFF during the Laser Off Time beginning at the start of the scan beam sweep and turns ON for the duration of the Laser On Time.

Laser On Position

Definition: Measured in increments equal to 1/100th of total scan width.

Serial Cmd:

Default: 10

Options: 10 to 90

Laser Off Position

Definition: Measured in increments equal to 1/100th of total scan width.

Serial Cmd:

Default: 95

Options: 15 to 95

Laser Power

Usage: Used to optimize read performance at different distances. Typically higher power is used at greater distances.

Definition: Allows the user or calibration routine to select laser power setting.

Serial Cmd:

Default: High Power (low or medium density scanner)

Options: 0 = Low (3.0 mW) 1 = Medium (3.25 mW) 2 = High (3.5 mW)

Read Rate by Serial Command

Enter Single Symbol Percent Test

Sending instructs the scanner to transmit the percentage of decodes and any scanned symbol data.

Enter Multisymbol Percent Test

Sending instructs the scanner to transmit the percentage of scans decoded and symbol data (if any) for multiple symbols.

Enter Single Symbol Read Rate Test

Sending instructs the scanner to transmit the decodes per second and symbol data (if any). The decode rate can vary dramatically due to the angle and location of the symbol in relation to the scan line. This test is very useful in aligning and positioning the scanning device during installation.

Enter Multisymbol Read Rate Test

Sending instructs the scanner to transmit the decode rate and symbol data (if any) for multiple symbols.

Enter Percent PDF Read Rate Test

Sending instructs the scanner to transmit the number of decodes per second on the full PDF symbol. This test includes both capture and decode and translation time. Note that the output format of the data is done as a running average of 750ms windows. This means that you can remove the symbol from the view of the scanner and it will continue to transmit some history of the symbol for a few outputs.

Sending the check box will cause PDF417 symbology data to be prefaced with information consisting of error correction level, number of rows, number of columns, number of informative code words and the number of data characters.

This feature can be disabled by using the exit read rate command .

Enable Extended Read Rate Test for Single and Multisymbol

Sending after or will generate a an extended mode that applies to both single and multiple symbols.

Extended Mode instructs the scanner to output the decode rate, the symbol data, and the transition data.

The example below shows output with Postamble enabled and defined as Carriage Return/Line Feed.

Note: The command has no immediate effect if not preceded by or .

End Read Rate Test

Sending ends both the Percent test and the Decodes/Second test for both single and multisymbol.

Counters

Counters

Counter commands can be a numeric value from 00000 to 65535. After reaching the maximum numeric limit of 65,535, the counter will automatically rollover and start counting again at 00000 and report any errors. To obtain the cumulative total of counts after the rollover has occurred, add 65,536 per each rollover (the scanner does not keep track of the number of rollovers) to the current count.

Note: All counter values will be lost if power is recycled to the scanner or the scanner receives a reset or save command.

Scanner Status Requests

Status Byte

The scanner responds to a status request <?> with a two character hex value, for example <?/22>. To determine the status:

1. Look up the binary conversion in the hex-to-binary table.

For example, the first 2 in binary would be 0 0 1 0 as read from binary digits 3 through 0; the second 2 the binary digits 7 through 4 which is also 0 0 1 0.

1. Next, enter your binary values in the "Scanner Status" table, in the "Binary" column next to the appropriate bit.

Bit Binary Scanner Status

0 0 Command error detected

1 1 Command received

2 0 Communication error detected

3 0 Flash sector unprotect failure

4 0 Host/Aux port buffer overflow

5 1 Scanner is in a read cycle

6 0 Software Watchdog reset

7 0 Hardware Watchdog reset

1. Under "Binary," interpret 1s as true and the 0s as not true. For example, bit 1 has a 1 in the "Binary" column, indicating "Command Received." Bit 5 is also a 1 indicating that the "Scanner is in a read cycle."

Hex Value	Binary Bit Digits
	7	6	5	4
	3	2	1	0

Symbol Number

Definition: Symbol Number refers to the number of the symbol to which output formatting will apply. For example, if you wish to enable user-defined formatting to symbol # 2 in a multisymbol read cycle, you would send the command . Note that the number of symbols may exceed the format capabilities.

Serial Cmd:

Options: 1 to 12

1 = Formatted output status for symbol # 1.
2 = Formatted output status for symbol # 2.
12 = Formatted output status for symbol # 12.

Format Assign Status

Definition: Status refers to the user-defined formatting of a selected symbol position in the read cycle result. Note that there is also a global formatting "enable" command that must be set for the formatting to be applied.

Format Extract

Output Index

Definition:

Output Index refers to the database entry you wish to modify with this command. A formatted output is built by extracting data from a symbol's original data output and/or inserting user-defined characters.

It may be helpful to think of individual indexes as positions in the final formatted output you wish to build. Starting with index # 1, enter either an extract or insert command to begin building your desired output string. Then, with the next index number, enter either an extract or insert command to continue building the output string. Continue this process until you are finished building the string.

Serial Cmd:

Options: 1 to 100

Start Location

Definition:

Defines the location within the symbol data where the character extraction will begin. The first character extracted will also be the first character in the sequence displayed in user-defined output.

Serial Cmd:

Default: 0

Options: 1 to n (maximum number of characters in symbol data)

Length

Definition: Defines the length (in consecutive characters) that will be extracted and placed in user-defined output.

Serial Cmd:

Default: 0 (disabled; end of format cell array)

Options: 1 to n (maximum number of characters in symbol data)

Format Assign

Format Extract by ESP

You can extract and insert several character sequences using ESP's Symbol Parse feature. In this example, the selected extraction range is characters 2-4. The "Sample Symbol" example on the Symbol Parse dialog shows the selected character positions extracted and output as desired. Simultaneously, the data string from the actual selected symbol is displayed at the bottom left of the Parse Table, followed by the user-defined extracted output.

Format Insert

Output Index

Definition:

Output Index refers to the database entry you wish to modify with this command. A formatted output is built by extracting data from a symbol's original data output and/or inserting user-defined characters.

It may be helpful to think of individual indexes as positions in the final formatted output you wish to build. Starting with index # 1, enter either an extract or insert command to begin building your desired output string. Then, with the next index number, enter either an extract or insert command to continue building the output string. Continue this process until you are finished building the string.

Serial Cmd:

Options: 1 to 100

Length

Definition:

Specifies the length of the user-defined character string that will be inserted. This function is limited to 4 characters per output index, so multiple indexes must be entered in order to insert longer character sequences.

For example, if you wish to insert a 10 character sequence in user-defined output, you would need three commands with consecutive index numbers, where the first two character sequence lengths were 4 and the third was 2.

Serial Cmd:

Default: 0 (disabled; end of format cell array)

Options: 1 to 4

Hex String

Definition:

Specifies a character string that represents ASCII characters to be inserted in the database entry. Two hex characters are required for every ASCII character to be inserted in the user-defined output string. These two characters comprise the hex (base 16) value of the ASCII character.

For example, if you wanted to enter the three-character sequence "Hi!" you would enter 3 for the length of the string, and a hex sequence of 486921 for the ASCII sequence to be inserted. (48 = H; 69 = i; 21 = !)

Important: Each pair of hex characters represents one ASCII character. Hex character pairs range from 00 to FF. Since you are limited to 4 ASCII characters per insertion per database entry, you are likewise limited to 8 hex characters per insertion per database entry.

Serial Cmd:

Default: NUL (00 in hex)

Options: 00 to FF (As many as 4 bytes, or hex pairs.)

Output Filter Configuration

Definition:

Output filtering is a method of providing a set of good read qualifiers and also providing ordered output. There is a filter for up to the first 10 positions in a multisymbol output. The first filter corresponds to the first symbol output at the end of the read cycle. Each filter has has settings for the following four parameters: Symbology Type, Symbol Length, Data, and Configuration Database Number.

Serial Cmd:

Rules for Output Filter Configuration

Output Filter Configuration Rule # 1

Each symbol that is decoded must match one of the filters before it can be saved to a read cycle record. There is an exception to this rule, however, when the number of symbols required for a read cycle exceeds the number of active filters. In such a case, unfiltered symbols can be placed into unfiltered output positions.

For example, if the number of symbols required is 6 but there are only 4 active filters, the last 2 positions can be filled by any (unfiltered) qualified symbol.

Output Filter Configuration Rule # 2

The same filter setup can be used multiple times.

For example, filters 1, 2, and 3 can be set up to filter Data Matrix symbols, and the output will occur in the order the symbols are decoded.

Output Filter Configuration Rule # 3

All qualified symbols will be sorted and output in the matching filter position. If a symbol matches filter 3, it will be output as the third symbol. If a filter does not have a matching qualified symbol, a No Read message will be output in place of the symbol (assuming the No Read message is enabled).

For example, if there is not a symbol that meets filter 3's requirements, then a No Read message will be output in the third output position.

Output Filter Configuration

Filter Number

Definition: This is the filter index number that represents the position of the symbol in the data output at the end of the read cycle. This index number should be entered along with the following filter settings for the predetermined symbol position.

Serial Cmd:

Options: 1 to 12

Symbology

Definition: Specifies the symbology type allowed to occupy this location in multisymbol output. Note: To filter or order a symbol, the symbol must meet all the requirements of the selected filter index.

Serial Cmd:

Default: 0 (any symbology type)

Options: 0 = Any type 1 = Interleaved 2 of 5 2 = Code 39 3 = Code 128 4 = Codabar 5 = UPC 6 = PDF417 7 = EAN 128 8 = Code 93 9 = Pharmacode

Length

Definition: Specifies the length of the decoded symbol allowed to occupy this location in multisymbol output.

Note: To filter or order a symbol, the symbol must meet all requirements of the selected filter index.

Serial Cmd:

Default: 0

Options: 0 to 128

Wildcard

Definition: This is the character to be used in the data output field when performing a data filter comparison. The wildcard character represents the end of matching, and allows for variable lengths of symbol output.

Serial Cmd:

Default: “ * ” = (2A in hex)

Options: Any ASCII input in the form of a pair of hex characters.

Example:

2A = *

00 = disabled

Placeholder

Definition: The placeholder character requires a character to be present, but does not compare the data value.

Serial Cmd:

Default: “?” = (3F in hex)

Options: Any ASCII input in the form of a pair of hex characters.

Example:

3F = ?

00 = disabled

Data

Definition: This is the data string to be used when comparing symbol data for output filtering and ordering. This data string may also contain wildcard and placeholder characters to facilitate matching. Remember that in order to filter or order symbol data, it must meet all the requirements of the selected filter index.
- Filter data = "123*". This will match data strings of "123", "123456", and "123ABC", but not "12".
- Filter data = "123*AB?C". This will be interpreted as "123*".
- Filter data = "123?". This will match "1234" and "123A", but not "123", "12345", or "1234C".
- Filter data = "123?A". This will match "1234A" and "123BA", but not "123", "1234C", or "1234ABCD".
- Filter data = "123?A?". This will match "1234AB" and "123BAT", but not "1234A" or "123BATS".
- Filter data = "12??*". This will match "1234", "123456", and "123ABC", but not "12" or "123".
- Filter data = "123?A*". This will match "1234A", "123BA", and "123BATS", but not "1234" or "1234C".

Examples:

Serial Cmd:

Default: NUL (00 in hex)

Options: Any ASCII input in the form of a pair of hex characters.

Maximum length: 63 bytes defined.

Examples:

$$ 4 1 4 2 2 \mathrm{A} = \mathrm{AB} ^ {*} $$

Data [0] = NUL represents string matching disabled.

Decode Direction

Definition: Decode direction is determined by the direction of the output filter.

Serial Cmd:

Default: 0 (any direction)

Options: 0 = Any Direction

1 = Forward

2 = Reverse

Database Index

Definition: The index of the database entry that decodes a given symbol must equal this setting for filtering to occur. A setting of 0 allows any database index for this filter entry.

Serial Cmd:

Default: 0

Options: 0 = Any Database Index

1 = Database # 1 to n (maximum number of characters in the symbol data)

Number of Filters

Number of Filters

Definition: Number of Filters refers to the number of active output filters. 0 disables all output filters. Any non-zero numeral will enable filtering to be performed using the filter indexes covered by this value. For example, if the number of filters is 1, then only filter index # 1 will be applied. If the number of filters is 2, then only filter index # 1 and filter index # 2 will be applied, etc.

Serial Cmd:

Default: 0

Options: 0 to 12

Wiring Box Ports

Relay Modules

These can be used as an alternative to the 3 optoisolated outputs from the scanner itself. K1, K2, and K3 are module sockets for SM off-the-shelf AC/DC output/relay modules.

Note: For relay module kits, use a slim module that does not exceed 0.43" (11 mm) in width.

Serial Command Format

Serial commands are of two types: utility and configuration.

Rules that apply to both utility and configuration commands

• A less than < and greater than > character enclose the commands.
• Commands and data are “case sensitive.” That is, characters must be entered as upper or lower case, as specified.

Serial Utility Commands

These are sent during operations and are not followed by or .

Serial Configuration "K" Commands

These begin with a single K character followed by a 3-digit numeric character, data fields, and an initializing command, as follows:

An initializing command or may follow the command. A initializes the scanner's memory and saves for power-on; an initializes the scanner's memory but does not save for power-on.

For example, to enable UPC and save the change for power-on, send .

To change Baud Rate and reset without saving changes for power-on, send .

Serial Configuration Command Conventions

• All data fields (except the last) must be followed by a comma (without a space).
• All fields preceding a modified field must be included.
• If there is no change in preceding fields, then commas alone can be entered in these fields. For example, if only the last field in the following command is changing, can be entered as .
• All fields following a modified field can be omitted. For example, to change Baud Rate only, send .

Concatenating Configuration Commands

Commands can be concatenated (added together) in a single string or data block. For example, enables LRC, sets End of Read Cycle mode to New Trigger, enables Narrow Margins, and resets the data buffers (without saving the changes for power-on).

Serial Command Status Request

To ensure that any command was received and accepted, you can send the Show Reader Status command: <?>.

The status of a specific serial command can be requested by entering the command followed by a question mark. For example, send to request the status of Postamble.

Entering Control Characters in Serial Commands

To enter control characters within a serial command, hold down the Ctrl key while typing the desired character.

Example: To enter a carriage return and line feed ( ^M J), enter

Entering Special Characters in Embedded Menus

Control Characters

Control characters entered on the command line are displayed in the menu as mnemonic characters, such as:

Press SP (the space bar) once, then enter the control character by holding down the control key and simultaneously pressing the desired character. For example to define a line feed, press SP, then Control and J simultaneously. It is displayed as ^J on the command line and as in the menu when the screen is refreshed.

To Define a Carriage Return as a Character

Press SP, then CR. It is displayed as ^M on the command line and as in the menu when the screen is refreshed.

To Define a Space as a Character

Press SP twice. It is displayed as a blank space in the menu when the screen is refreshed. While it appears that nothing has been assigned, the hex value 20 will be sent during data transmission.

To Select NUL as the Character

Press SP, then a 0. It is displayed as in the menu when the screen is refreshed.

1. With your host connected to the 9-pin configuration port, set your host communications settings as follows: 57.6K baud, 8 Data Bits, 1 Stop Bits, and None Parity. OR, with your host connected to the 25-pin configuration port, set your host communications settings as follows: 9600, 7, 1, and Even.
2. Set Flow Control to None.
3. Make the communications port selection. (Usually COM 1 or COM 2 for desktops and COM 1 for laptops.)
4. Upon connection, send a command to bring up the main menu.

Note: The 9-pin configuration port settings are fixed.

Important: To receive symbol data through the 9-pin configuration port, you must enable the port with the following command: .

1. Press the return key (CR) to view the communications menu.

Menu navigation commands are case sensitive. Use the space bar or N to advance to the next item, CR (return key) to select a highlighted item, B to return to the previous item, M to return to the previous menu, and ESC to return to the Main menu or to exit the program. When exiting the program, you will be prompted to save your active settings for power up (Y or N). Typing Y will be equivalent to saving with a command.

Appendix F — Defaulting/Saving/Initializing

Active Memory is where the scanner's settings are stored during current use and are initialized by an command.

Microscan Defaults are where the scanner's default application/boot programs are stored. They can only be changed by changing the application/boot codes. ^1

User-Saved Settings are where user-defined settings are saved for power-on.

Defaulting

Defaulting occurs when default settings (either Microscan or user-saved) are restored. Defaulting might be necessary if you have to make temporary changes, communications between the scanner and another device are lost or interrupted, or you are using incompatible equipment (for example, a terminal that is set at 9600 baud communicating with a scanner that is set at 38.4K baud).

Restore User-Saved Settings to Active Memory

• Restores user-defined settings to active memory.
• Initializes serial configuration commands in active memory and resets counters to zero.

Restore User-Saved Settings to Active Memory by Serial Command

Send command to the scanner.

Note: There is no equivalent ESP command.

Restore Microscan Defaults to Active Memory

• Restores Microscan defaults to active memory.
• Initializes serial configuration commands in active memory and resets counters to zero.
• Does not save settings for power-on.

Restore Microscan Defaults to Active Memory by ESP

Right-click in the configuration window and select Default All ESP Settings.

Restore Microscan Defaults to Active Memory and Power-On

Caution: Defaulting the scanner to Microscan default settings will overwrite user-saved settings.

• Restores Microscan defaults to memory.
• Restores Microscan defaults to user-saved settings for power-on.
• Initializes serial configuration commands in active memory and resets counters to zero.

Restore Microscan Defaults to Active Memory and Power-On

Send command to the scanner.

Restore Microscan Defaults to Active Memory and Power-On by ESP

1. Right-click in the configuration window and select Default All ESP Settings.
2. Right-click and select Save to Reader and Send and Save.

Restore Microscan Defaults by Hardware Default

There is no hardware default for the MS-890. Default commands can be entered from any of the host connectors. Since the default communications settings on the 9-pin connector are fixed, you can always send a default the scanner through this port with a software command.

Saving

Power-On settings are those that are saved by a command and are loaded into active memory whenever power to the scanner is recycled.

Save Active Settings (Except Factory) for Power-On

Initializes serial configuration commands into active memory and resets counters to zero. Saves all current settings except factory settings to user-saved settings for power-on.

Save Active Settings (Except Factory) for Power-On by Serial Command

Send command to the scanner.

Save Active Settings (Except Factory) for Power-On by ESP

Right-click in the configuration window and select Save to Reader, then Send and Save.

Initializing

Initializing occurs whenever any command or set of commands is implemented.

Initializing is a part of all save and default functions. It is also used as a follow-on to implement serial configuration commands.

• Initializes serial configuration commands into active memory and resets counters to zero.
• Does not save settings for power-on.

Initializing by Serial Command

Send after a serial configuration command or a string of serial configuration commands. For example: .

Initializing by ESP

Right-click in the configuration window and select Save to Reader, Send No Save. This will initialize all serial configuration changes that have been made in the current ESP session.

Note: Allow a 1.5 second delay after sending the command before resuming communications.

Loss of Communications

Making changes to communications with the host such as Baud Rate, Parity, Stop Bits, LRC, etc. without corresponding changes in linked device(s) can result in the loss of menu access through the 25-pin port and wiring box connections. If this should occur, connect the scanner to the 9-pin port and set your host communications settings as follows: 57.6K baud, 8 Data Bits, 1 Stop Bits, and None Parity. These settings for this port are fixed and cannot be changed. you should restore the scanner's defaults. If you wish to return to the 25-pin host port, you'll first need to change the scanner's communications settings by sending: .

Appendix G — Position Scanner and Symbol

In positioning the scanner in relation to the symbols being scanner, consider the following:

• Position the scanner in a place devoid of sunlight, bright lights, or laser light from other sources.
• Avoid excessive tilt, skew, or pitch. Maximum tilt is determined by symbol characteristics and the number of decodes required. Maximum skew is ± 40^ ; maximum pitch is ± 50^ .
• Pitch symbol (or scanner) slightly to avoid specular reflection, the return of direct, non-diffused light. Specular reflection is avoided by pitching symbols at least 5^ plus or minus from a line perpendicular to the default position of the Raster Bottom and Raster Top. ^2

Note: Another way to avoid specular reflection is to skew the scanner slightly in relation to the symbol.

Object Detector

Appendix H — Object Detector

In a typical operation, a scanner will wait for symbol data only during a triggered read cycle. A read cycle is initiated by a “trigger” and can be in the form of a serial command from the host (internal trigger) or a signal from an object detector (external trigger).

When an object detector (also called a sensor, package detector, etc.) is used, it is set up so that its beam will bounce off the approaching object and the resulting pulse will be sent to the scanner to begin the read cycle. Typically, a detector is positioned so that it will detect the presence of an object before its symbol can be scanned.

An object detector is mounted in almost any position relative to the object as long as:

(1) the object passes within range of the detector and
(2) direct or reflected light from the detector does not interfere with the scanner's reception.
As the item continues to move down the line, its symbol moves into the scanner beam and is read by the scanner.

The drawing below shows a symbol in the picket fence direction with the object detector positioned so as not to cause interference.

Appendix I — Bar Code Configuration

You can configure the MS-890 by presenting Code 128 symbols encoded with serial commands.

Note: Your scanner does not need to be enabled for Code 128 in order to enter Bar Code Configuration.

Entering Bar Code Configuration

The symbol used to enter configuration is the 7-character code 128 symbol shown below. It is not required that the scanner be configured to read code 128 symbols to read this start symbol or the following configuration symbols.

To set up Bar Code Configuration:

1. Put the scanner in a read cycle mode.
2. Place a special Code 128 configuration Start symbol (provided below) in the scanner's field of view.

If the scanner is able to read the Start symbol, it will begin to beep and the performance LEDs will activate.

1. When the scanner starts to beep, remove the configuration symbol from the scanner's field of view.

The scanner is now in Bar Code Configuration mode.

During Bar Code Configuration mode, the LEDs will illuminate in a sequential pattern to indicate that the scanner is ready to be configured.

You can create your own start symbol by encoding the following character sequence in a Code 128 symbol:

FNC4 <_CFG>

Using Configuration Symbols

Once in Bar Code Configuration mode, serial command data encoded in Code 128 symbols is decoded by the scanner as serial input.

Configuration symbols must meet the following conditions:

1. The only valid symbology for Bar Code Configuration is Code 128.
2. Symbol data may contain more than one command, but individual symbols must be presented individually. This is because only the first symbol in a read cycle will be used as a possible configuration symbol. A symbol that is presented to the scanner must be read 25 times consecutively to be used as a valid symbol.

Once this is done, the scanner will interpret the symbol data in the same fashion as it interprets serial data.

1. Any valid command may be encoded in Code 128 symbols, including operational commands.

Because the data is treated like serial input, multiple symbols may be used to represent one command as long as the symbols are presented individually and in the correct order.

1. Read Rate commands may also be used to enter Read Rate from Bar Code Configuration mode.

2. When in Read Rate, the scanner will read the symbologies that were enabled prior to entering Bar Code Configuration mode. However, the scanner will read a in Code 128 regardless of the current enable/disable state of Code 128.

Once the is issued, the scanner will exit both Read Rate and Bar Code Configuration mode. To exit Read Rate and remain in Bar Code Configuration mode, present the start symbol once again. Symbols decoded during Read Rate will not configure the scanner.

Scan the symbol shown to the right to start a Read Rate test.

Exiting Bar Code Configuration

There are multiple ways of exiting Bar Code Configuration.

The first way is simply to decode a symbol encoded with the command, or to enter a command from a terminal. The scanner will beep when exiting Bar Code Configuration in response to a command.

Any command that executes a software reset will also end Bar Code Configuration mode. These commands include the Save family as well as the Reset family (, , , ).

To end the Read Rate test and Bar Code Configuration mode, scan this symbol:

Configuration changes will remain in effect, as would changes made by using serial commands or ESP.

Appendix J — Test Read Rate

Test Read Rate by Bar Code Configuration

You can enter a Read Rate test by scanning the following symbols:

Enable Bar Code Configuration

(Also activates the scanner's read performance LEDs.)

Enable All Symbologies

Start Read Rate Test

End Read Rate Test and Disable Bar Code Configuration

Test Read Rate by Serial Command (Static Symbol)

1. Position a stationary symbol in front of a functioning scanner at the scan distance used in your application.
2. Set for single scan line scanning (Raster Top setting equal to Raster Bottom).
3. Enter a command to see the decodes per second.

The decode rate is the number of decoded scans per total number of scan. It will appear at the beginning of the data strings.

Note: You can also enter a command to see the percentage of decodes per scans.

1. Make a note of the decode rate. You will need this when calculating the number of decodes (see Appendix K, Formulas for Number of Decodes on page A-27).
2. End the test by sending the command.

Test Read Rate by ESP

See Read Rate in Chapter 12, Utilities.

Test Read Rate with a Moving Symbol

Before testing with a moving symbol, it is highly recommended that you calculate the expected number of decodes by using the formulas in Appendix K, Formulas for Number of Decodes on page A-27.

Once you've mounted the scanner, established a good read rate with a stationary symbol, and calculated the number of decodes for your symbol speed, you can begin decoding with moving symbols.

Number of Decodes

To ensure reliable scanning, you need to apply a minimum of five decodes to each symbol. This means that all variables, symbol speed, read range, etc. are significant.

Note: Variations between symbols are common. For this reason, the greater the number of sample symbols tested, the more likely you are to achieve optimum decode rates.

In general, the number of decodes of a given symbol can be increased by:

• Increasing symbol height
  • Decreasing symbol length
• Increasing scan rate (spinning mirror speed)
• Slowing symbol speed
  • Decreasing raster sweep rate
  • Decreasing raster height

Appendix K — Formulas for Number of Decodes

To ensure reliable scanning, apply a minimum of five decodes to each symbol. Use the formulas below to calculate the number of decodes that your symbol will receive.

If the number of decodes you derive from one of these calculations is less than the minimum for your application, plug in the minimum number of decodes (5) and solve for another parameter that might be changed, such as symbol speed or scans per second.

Note: While the formulas given here solve for the predicted number of decodes, you may also use the formulas to solve for other parameters that might be changed, such as symbol speed, symbol length, etc.

Single Line Ladder Calculation

Ladder scanning is seldom done with raster scanning unless the raster is set for single scan line scanning (Top Offset setting equal to Bottom Offset) or symbols are presented as stop-and-go.

For single scan line ladder scanning, use the following formula: ^1

$$ \mathrm{ND} = \left(\frac {\mathrm{SH}}{\mathrm{SS}} \cdot \mathrm{DR}\right) - 3 $$

ND (Number of Decodes) is the number of decodes that a given symbol can be expected to achieve in a given application.

Direction Scan Line

Single Line Ladder Orientation

SH (Symbol Height) is a measurement of the height of individual bars.

SS (Symbol Speed) is the distance per second that a symbol moves through the scan.

DR (Decode Rate) is the number of scans per second that a given symbol receives.

Example:

SH = 0.5, SS = 10/second, and DR = 200 decodes per second

$$ \mathrm{ND} = \left(\frac {0 . 5}{1 0} \cdot 2 0 0\right) - 3 = 1 0 \text { complete decodes } $$

Raster Picket Fence Calculation

For raster picket fence scanning, the number of decodes (ND) that can be applied to a given symbol can be calculated once the sweep rate (SPS) is known.

Sweep Rate (Sweeps per Second)

Sweep rate is the number of raster sweeps (up or down) that occur per second and can be set in ESP. Since the sweep rate cannot exceed 30, you first need to ensure that your application can achieve this by solving for sweep rate (SPS). The sweep rate should generally be set as low as possible in order to maximize the number of scans on a given symbol.

The formula for finding Sweep Rate (SPS) is as follows:

$$ S P S = \frac {2 \cdot \mathrm{SS}}{(\mathrm{SW} - \mathrm{SL})} $$

Direction Raster pattern

Raster Picket Fence Orientation

SPS = Sweeps per Second, the number of passes, up or down, that are described by the arc of the raster mirror.

SS = Symbol Speed, the inches per second that a symbol moves through the scan.

SW = Scan Width, the width across the scan beam, at a given distance from the scanner, in which a symbol can be read (picket fence formula only).

SL = Symbol Length, the length of the longest printed symbol to be read plus the length of the quiet zones (picket fence formula only).

Example:

$$ \begin{array}{l} \mathrm{SW} = 5 \ \mathrm{SS} = 2 \text { per second } \ \mathrm{SPS} = \frac {2 \cdot 2}{(5 - 1)} = 1 \ \mathrm{SL} = 1 \ \end{array} $$

Important: The maximum sweep rate that your can set the scanner to is 30. If your solution is greater than 30, you must change another parameter such as symbol speed, etc., and recalculate.

Since SPS can only be entered into the software as whole numbers, round off fractions of SPS to the next higher number, for example enter 0.4 as 1 and 3.5 as 4.

In setting up the scanner, raster height depends on the raster arc and the symbol distance (range) from the scanner. Both the top offset and bottom offsets can be adjusted independently in 255 increments and the resulting arc can vary from 0^ to 30^ . (See Chapter 10, Raster/Laser.)

Number of Decodes

Note: Because adjustable raster sweeps and scan speeds cannot be synchronized, some variation in raster height should be anticipated.

Number of decodes (ND) for a raster picket fence symbol is calculated by the following formula:

$$ \mathrm{ND} = \left(\frac {\mathrm{SH} \cdot \mathrm{DR}}{\mathrm{RH} \cdot \mathrm{SPS}}\right) - 3 $$

ND = Number of Decodes (total applied to each symbol)

SH = Symbol Height

DR = Decode Rate

RH = Raster Height

SPS = Sweeps per Second

Example:

$$ \mathrm{SH} = 1, \mathrm{DR} = 1 0 0, \mathrm{RH} = 1 0, \mathrm{SPS} = 1 $$

$$ \mathrm{ND} = \left(\frac {1 \cdot 9 0 0}{1 0 \cdot 1}\right) - 3 = 8 7 \text { decodes } $$

Raster Height

If raster arc (in degrees) and symbol range are known, raster height can be derived by the following formula, where is raster arc in degrees: ^1

$$ \mathrm{RH} = (2 \cdot \text { Symbol Range }) \tan \left(\frac {\neg}{2}\right) $$

Raster Arc

If raster height and symbol range are known, then raster arc can be derived by using the following formula where RH is raster height:

$$ \neg = 2 \cdot \operatorname{atan} \left(\frac {\mathrm{RH}}{2 \cdot \text {Symbol Range}}\right) $$

Note: Raster arc is not presented in degrees in ESP. To convert to degrees, add the Top Offset to the Bottom Offset and subtract the sum from 255. Enter this as the offset in the following formula:

$$ \text { Degrees } = \frac {\text { Offset } \cdot 3 0}{2 5 5} $$

Formulas for Number of Decodes

Single Line Picket Fence Calculation

For single scan line picket fence scanning (Top Offset setting equal to Bottom Offset), use the following formula:

$$ \mathrm{ND} = \left(\frac {(\mathrm{SW} - \mathrm{SL})}{\mathrm{SS}} \cdot \mathrm{DR}\right) - 3 $$

ND = Number of Decodes (total applied to each symbol)

SW = Scan Width

SL = Symbol Length

SS = Symbol Speed

DR = Decode Rate

Direction Scan Line

Single Line Picket Fence Orientation

Example:

SL = 2 inches (including quiet zones)

SS = 100 inches per second

SW = 4 inches

DR = 1000 decodes per second

((4 - 2)100 · 1000) - 3 = 17 complete decodes

Angled Picket Fence Calculation

The number of complete scans for angled picket fence is calculated the same as that for picket fence, with the exception that the scan width is shortened in proportion to scan tilt.

Direction of label travel Scan Line

Angled Picket Fence Orientation

Improving Decode Rate

After changing any of the parameters described in this section, recalculate the number of decodes.

Scan Rate

Scan rate is a function of motor speed and is adjustable. A slower scan rate may allow greater symbol range and/or higher decode rates, but at the cost of fewer scans per symbol and scan width.

Range

Adjusting the symbol's range, if possible, is one of the quickest and most effective ways to improve decode rates. However, in some applications you may need to select a less than optimum range, or one that is beyond the fringes of the ranges.

Scan Width

Increasing scan width will increase the number of scans in a picket fence oriented application. Scan width is linked with scan range and changing one will usually require a change in the other.

Symbol Speed

Applies to both picket fence and ladder oriented symbols. If your application allows it, slowing symbol speed (the time in seconds that a symbol is fully within the scan width of the scanner) is an effective way to increase the number of decodes.

Raster Height

When using the raster features, you can increase the decode rate by decreasing the height of the raster image.

Raster Sweep Rate

Slowing the number of sweeps per second to the minimum needed will result in more scan lines passing over the symbol and a higher decode rate.

Laser Framing

Narrowing the laser frame may not increase the decode rate, but it will minimize the opportunity of extraneous reads.

Symbol Dimensions, Symbol Density, and Symbol Ratio

Not usually an option in most applications, but changes to symbol parameters can affect number of decodes calculations and possibly decode rates.

If your application allows it, shortening the length of a picket fence symbol means the symbol will be in the scan range longer and hence receive a greater number of scans. Increasing the height of a ladder symbol means it will receive more scans. Changing symbol density and/or symbol ratio is another way ranges, decode rates, etc. can be altered.

Gain and Tracking

These adjustments, typically made by qualified technicians, are referenced in the Scanner Setup menu (see Defaulting/Saving/Initializing on page A-18). Changes to tracking will generally have a limited effect on decode rates.

Appendix L — Operational Tips

Do:

• Check inputs (symbol speed, length, height, etc.) to ensure the desired number of decodes per symbol.
• For optimum decodes, mount scanner so that your symbols pass through the center of the depth-of-field (minimum/maximum range). You find the center by moving your symbol in and out during a read rate test.
• Avoid excessive tilt, pitch, and skew of the symbol.
• Check the symbol for readability by doing a decode rate test. If there is any question about the symbol's readability, contact your Microscan sales representative.
  • After changing any parameter that might affect decode rate, repeat decode rate test.
• Clean the scanner window with a clean, dry cotton swab or cotton cloth on a regular basis.

Do Not:

• Aim the scanner into direct light or sunlight.
• Aim the scanner into an external object detector or other light-emitting device.
• Obstruct the scanner window with mounting hardware or other objects.
• Connect chassis of scanner and host to different ground potentials.
• Operate the scanner in excessive temperature environments.

Appendix M — Interface Standards

Interface Standards, established by the Electronic Industries Association (EIA), specify such things as the signaling voltage levels, maximum cable lengths, and number of drivers. With Microscan devices, selection of interface is made by pin assignment and, in the case of the host communications, by software switching between RS-232 and RS-422. Microscan devices use RS-232, RS-422, and RS-485 multidrop.

RS-232

RS-232 defines an interface between two devices such as, for example, the scanner and host. It differs from the other interfaces by dedicating individual pins to specific functions and by requiring both devices to share a common ground line. Since both device chassis are connected to a common ground, a ground loop potential and the possibility of noise interference exists. Therefore cable lengths are limited to a maximum of 50 feet (19.7m). Despite being the most limited, this interface is used frequently because of the large installed base of RS-232 equipment.

RS-422

RS-422, unlike RS-232, measures signals deferentially; that is, the receiver looks at the potentials between the two receive (or transmit) wires rather than the potential between signal and ground. As a result, cables, if shielded, can be up to 4000 feet (1219m) in length. Like RS-232, RS-422 communication is designed for only two devices on a single line and must have a common ground. It can be used wherever RS-232 is used.

RS-485

RS-485, like RS-422, can transmit up to 4000 feet (1219 m) using differential voltages but unlike RS-422, its transmitters are turned off until a request for data is received from the host. RS-485 is used exclusively in Multidrop protocol.

Appendix N — Multidrop Communications

This appendix describes the rules for setting up a concentrator or controller to communicate with a scanner in standard Multidrop protocol.

The diagram to the right shows a typical Multidrop network in which 1 to 50 scanners can communicate with a host via an intermediary device, a concentrator, or a controller.

Multidrop

Configure Scanner for Multidrop

1. With the scanner connected to the host, Retrieve Reader Settings.
2. Select Multidrop in the Protocol configuration menu.

You will see the following message:

Important: You must change your preamble and postamble characters so that they are not CR or NUL.

This allows data to move through the concentrator without interference.

1. Click OK.
2. Next, go to Preamble Characters (still in the Protocol menu) and double-click on Characters.
3. This will open up an ASCII character table. Select any character but CR.
4. Repeat the above process for Postamble.
5. Check the multidrop address. Enter a number from 01 to 50.
6. Right-click in the window and select Save to Reader and Send and Save.
7. Your scanner is now in Multidrop. From here on, you will need to use the concentrator to relay commands and data between the scanner or scanners and the host.
8. Move on to Connect to Scanner via Concentrator.

Connect to Scanner via Concentrator

You will need a multidrop concentrator and the required power supplies and cabling to communicate with your scanner(s).

1. From the Communications dropdown menu in the menu toolbar, select Configure Multidrop. The Multidrop Settings dialog will appear.
2. If necessary, change the default address to match the address of your multidropped scanner and click OK.

If the host serial port is not connected in ESP, you will see the following popup message:

"ESP is not currently connected to the multidrop concentrator. Do you wish to establish a connection now?"

Multidrop Settings ✓ Multidrop Used Address 01 ETX CR ✓ Second Multidrop Concentrator Used Address 01 ETX CR OK Cancel

1. Click Yes.
2. The Connection Settings dialog will appear. Notice that the Force Connect option is checked. Do not change this.
3. Select the concentrator's host port communications settings.

When you click Connect, you will be connecting to your concentrator, which can then relay commands to the scanner whose address was set in the Multidrop Settings dialog.

1. Click Connect.

You should see the CONNECTED message in green at the bottom of the window along with the scanner's Multidrop address.

Connection Settings RS-232 | TCPMP Baud: 9600° Patty: Even' Stop Bit: One' Data Bit: Seven' Port: COM1 □ Back Port In Use ☑ Force Connect Connect Cancel

1. Click Retrieve Reader Settings to upload the scanner's configuration. If upload fails, return to the Connection Settings dialog and make the necessary parameter changes.
2. Follow the same procedure for connecting other scanners to your multidrop network.

Polling Sequence

Data that is transmitted to the host (symbol data, No Read messages, counters, etc.) via concentrators is solicited by poll requests from the host.

The polling sequence example by poll address 1E (ASCII hex value for Scanner 02) and a REQ (request). The scanner responds by first transmitting its own address, 1E, followed by a STX (start of text) character, and then the data. Next it transmits an ETX (end of text) character and an LRC (longitudinal redundancy check) character.

If the concentrator (or controller) receives the data from the scanner and is able to validate it with an LRC calculation, it responds with an ACK (acknowledgment). If the scanner in turn receives the ACK, the scanner ends this successful exchange with a RES (reset).

graph LR
    A["Start of Sequence"] --> B["Concentrator RES 1E REQ ACK"]
    B --> C["Scanner 02 1E $TX DATA ETX LRC RES"]
    D["End of Sequence"] --> E["End of Sequence"]

Polling Sequence

Polling Reset

• If the scanner has no information, it responds to a poll request by transmitting a RES (reset).
• If the scanner receives a NAK instead of the ACK after transmitting its data string, it will re-attempt to send the data string up to three times. If the scanner still does not receive an ACK, it will send a RES (reset) and discard the data in its buffers.
• If the scanner transmits data to the concentrator and the concentrator responds with an ACK or NAK, but the scanner doesn't receive the concentrator's response, the scanner will timeout and send a REQ to the concentrator and request another response. If after three retries (the number of times it transmits a REQ to the concentrator) the scanner receives no response, it ends the transmission with a RES (reset).

Select Sequence

Unlike poll requests, select commands always originate from the host and consist of serial configuration or operation commands to devices that are configured in Multidrop. The scanner complies with the command when it is polled during the cycle.

graph LR
    A["Start of Sequence"] --> B["Concentrator RES 1F REQ STX <T>ETX LRC RES"]
    B --> C["Scanner 02 1F ACK 1F ACK"]
    D["End of Sequence"] --> E["End of Sequence"]

Polling Sequence

A RES (reset) is the first command in the select sequence. The 1F hex is the select address associated with Scanner 02 address. It is followed by a REQ (request). The scanner responds with its own select address, 1F hex, and an ACK (acknowledge). The concentrator then transmits an STX (start of text), the data (in this case a ), an ETX (end of text), and an LRC character.

The scanner replies by transmitting its own address, followed by an ACK, acknowledging receipt of the command. Upon receipt of an ACK, the concentrator concludes the successful exchange with a RES.

In the example above, the scanner only acknowledges a trigger counter request from the concentrator. It does not respond to the trigger counter request until a subsequent poll. For example, if the scanner's trigger count was 12 at the time the trigger counter request was received, on a subsequent poll it would send 02T/00012. (The 02 at the beginning of the string is the scanner's address.)

Select Reset

If the scanner receives bad data from the concentrator, it transmits a SEL (its select address) and a NAK to the concentrator. The concentrator re-transmits the data up to three times. The concentrator will end the sequence with a RES (reset) if no ACK is received.
