(Default: 0.0 sec.)

2.8 Time out between same symbol

When in Continuous triggering mode, this parameter sets the minimum time that must elapse before the scan engine decodes a second bar code identical to one just decoded. This reduces the risk of accidentally scanning the same symbol twice. It is programmable in 0.1 second increments from 0.0 to 9.9 seconds.

Time-out Between Same Symbol (Default: 1.0 sec.)

To set a time-out between same symbol, scan the bar code below. Next scan two numeric bar codes beginning on page 79Appendix B that correspond to the desired time-out. Single digit values must have a leading zero. For example, to set a time-out of 0.5 seconds, scan the bar code below, then scan the "0" and "5" bar codes. To change the selection or cancel an incorrect entry, scan Cancel on page 79Appendix B.

2.9 Transmit "No Read" message

Enable this option to transmit "NR" if a symbol does not decode during the timeout period or before the trigger is released. Any enabled prefix or suffixes are appended around this message.

Enable No Read (0x01)

When disabled, and a symbol cannot be decoded, no message is sent to the host.

*Disable No Read

2.10 Prefix / Suffix

2.10.1 Prefix/Suffix Values

A prefix and/or one or two suffixes can be appended to scan data for use in data editing. To set these values, scan a four-digit number (i.e. four bar codes) that corresponds to ASCII values. See the Table 2-1 and Numeric Bar Codes on page 79Appendix B. To change the selection or cancel an incorrect entry, scan Cancel on page 79Appendix B.

2.10.3 Data Transmission Format

To change Data Transmission Format, scan one of the eight bar codes corresponding to the desired format.

2.11 RS232 Setting

2.11.1 RS232 Baud Rate

Baud rate is the number of bits of data transmitted per second. Scan one of the following bar codes to set the engine's baud rate to match the baud rate setting of the host device. Otherwise, data may not reach the host device or may reach it in distorted form.

2.11.2 RS232 Data Bits

This parameter allows the engine to interface with devices requiring a 7-bit or 8-bit ASCII protocol.

Data Bits 8 bits*

Data Bits 7 bits

2.11.3 RS232 Stop Bits

The stop bit(s) at the end of each transmitted character marks the end of transmission of one character and prepares the receiving device for the next character in the serial data stream. Scan one of the following bar codes to set the number of stop bits (one or two) based on the number the receiving host can accommodate.

Stop Bits 1 bit *

Stop Bits 2 bits

2.11.4 RS232 Parity Check

A parity check bit is the most significant bit of each ASCII coded character.

Scan one of the following bar codes to select the parity type according to host device requirements:

- Odd - This sets the parity bit value to 0 or 1, based on data, to ensure that the coded character contains an odd number of 1 bits.

•Even - This sets the parity bit value to 0 or 1, based on data, to ensure that the coded character contains an even number of 1 bits.

- None - No parity bit is required.

2.11.5 RS232 CTS/RTS Handshaking

The data interface consists of an RS-232 port designed to operate either with or without the hardware handshaking lines Request to Send (RTS) and Clear to Send (CTS).

The DTR signal is jumpered to the active state.

Options:

- None - This disables hardware handshaking and transmits scan data as it becomes available.

- Standard RTS/CTS - This sets standard RTS/CTS hardware handshaking and transmits scanned data according to the following sequence:

a. The engine reads the CTS line for activity:

- If the CTS line is de-asserted, the engine asserts the RTS line and waits up to Host Serial Response Timeout for the host to assert CTS, and then transmits data when asserted. If, after the timeout, the CTS line is not asserted, the engine sounds a transmit error and discards the data. - If CTS is asserted, the engine waits up to Host Serial Response Timeout for the host to de-assert CTS. If after this timeout the CTS line is still asserted, the engine sounds a transmit error and discards the scanned data.

b. The engine de-asserts RTS after sending the last character of data.

c. The host negates CTS. The engine checks for a deasserted CTS upon the next data transmission.

During data transmission, if CTS is deasserted for more than 50 ms between characters, the engine sounds a transmit error and discards the data. The data must be re-scanned.

- RTS/CTS Option 1 - The engine asserts RTS before transmitting and ignores the state of CTS. The engine de-asserts RTS when transmission completes.

- RTS/CTS Option 2 - RTS is always high or low (user-programmed logic level). However, the engine waits for the host to assert CTS before transmitting data. If CTS is not asserted within the Host Serial Response Timeout, the engine sounds a transmit error and discards the data. During data transmission, if CTS is deasserted for more than 50 ms between characters, the engine sounds a transmit error and discards the data.

- RTS/CTS Option 3 - This transmits scanned data according to the following sequence:

a. The engine asserts RTS before data transmission, regardless of the state of CTS.
b. The engine waits up to the Host Serial Response Timeout for the host to assert CTS, and then transmits data when asserted. If, after the timeout, the CTS line is not asserted, the engine sounds a transmit error and discards the data.
c. The engine de-asserts RTS after sending the last character of data.
d. The host negates CTS. The engine checks for a de-asserted CTS upon the next data transmission.

During data transmission, if CTS is deasserted for more than 50 ms between characters, the engine sounds a transmit error and discards the data. The data must be re-scanned.

3.1.8 Decode UPC/EAN Supplementals

Supplementals are bar codes appended according to specific format conventions (e.g., UPC A+2, UPC E+2, EAN 13+2). The following options are available:

- If you select Ignore UPC/EAN with Supplementals, and the scanner is presented with a UPC/EAN plus supplemental symbol, the scanner decodes UPC/EAN and ignores the supplemental characters.

- If you select Decode UPC/EAN with Supplementals, the scanner only decodes UPC/EAN symbols with supplemental characters, and ignores symbols without supplementals.

- If you select Autodiscriminate UPC/EAN Supplementals, the scanner decodes UPC/EAN symbols with supplemental characters immediately. If the symbol does not have a supplemental, the scanner must decode the bar code the number of times set via Decode UPC/EAN Supplemental Redundancy before transmitting its data to confirm that there is no supplemental.

- If you select one of the following Supplemental Mode options, the scanner immediately transmits EAN-13 bar codes starting with that prefix that have supplemental characters. If the symbol does not have a supplemental, the scanner must decode the bar code the number of times set via Decode UPC/EAN Supplemental Redundancy before transmitting its data to confirm that there is no supplemental. The scanner transmits UPC/EAN bar codes that do not have that prefix immediately.

• Enable 378/379 Supplemental Mode.
• Enable 978/979 Supplemental Mode.

Disable GS1-128

*Enable GS1-128

GS1-128 (formerly UCC/EAN-128)

GS1-128 is a convention for printing data fields with standard Code 128 bar code symbols. GS1-128 symbols are distinguished by a leading FNC 1 character as the first or second character in the symbol. Other FNC 1 characters are used to delineate fields.

When GS1-128 symbols are read, they are transmitted after special formatting strips off the leading FNC 1 character, and replaces other FNC 1 characters with the ASCII 29 (GS) control character.

When AIM symbology identifiers are transmitted, the modifier character indicates the position of the leading FNC 1 character according to AIM guidelines. For example, ]c1 indicates a GS1-128 symbol with a leading FNC1 character.

Standard Code 128 bar codes which do not have a leading FNC 1 may still be used, but are not encoded according to the GS1-128 convention. Standard Code 128 and GS1-128 may be mixed in an application. The scanner auto discriminates between these symbols, and can enable or disable one or both code types. Table 3-1 indicates the behavior of the scanner in each of the four possible parameter settings.

Table 3-1 Reading Standard Code 128 & GS1-128

3.3.5 Set Lengths for Code 39

The length of a code refers to the number of characters (i.e., human readable characters), including check digit(s) the code contains. Lengths for Code 39 may be set for any length, one or two discrete lengths, or lengths within a specific range. If Code 39 Full ASCII is enabled, Length Within a Range or Any Length are the preferred options.

NOTE When setting lengths, single digit numbers must always be preceded by a leading zero.

One Discrete Length - This option limits decodes to only those Code 39 symbols containing a selected length. Lengths are selected from the numeric bar codes beginning on page 79Appendix B. For example, to decode only Code 39 symbols with 14 characters, scan Code 39 - One Discrete Length, then scan 1 followed by 4. To change the selection or cancel an incorrect entry, scan Cancel on page 79Appendix B.

Code 39 - One Discrete Length

Two Discrete Lengths - This option limits decodes to only those Code 39 symbols containing either of two selected lengths. Lengths are selected from the numeric bar codes beginning on page-79Appendix B. For example, to decode only those Code 39 symbols containing either 2 or 14 characters, select Code 39 - Two Discrete Lengths, then scan 0, 2, 1, and then 4. To change the selection or cancel an incorrect entry, scan Cancel on page-79Appendix B.

Code 39 - Two Discrete Lengths

Length Within Range - This option limits decodes to only those Code 39 symbols within a specified range. For example, to decode Code 39 symbols containing between 4 and 12 characters, first scan Code 39 - Length Within Range. Then scan 0, 4, 1, and 2. Numeric bar codes begin on page-79Appendix B. To change the selection or cancel an incorrect entry, scan Cancel on page-79Appendix B.
