3 Overview

The VP-81KSi routes any input to both outputs, using 15-pin HD female connectors for the computer graphics video signals, a 3.5mm mini jack for the unbalanced stereo audio Output 1 signal, and a detachable terminal block connector for the balanced stereo audio Output 2 signal.

In particular, the VP-81KSi:

• Has a very high video bandwidth ensuring transparent WUXGA performance
• Features audio-follow-video (AFV) in which all operations relate to both the video and the audio channels, or audio breakaway option, in which video and audio channels are switched independently
• Features volume control
• Includes the Kramer innovative integrated sync processing Kr-isp™ technology, which lets you achieve a sharp, stable image even when the sync level is too low, by restoring the sync signal waveform
• Up to eight units can be cascaded to provide a single “virtual” switcher with up to 57 inputs
• Supports the SI-1VGA Remote Step-in Panel for remote inputs and remote step-in control

You can control the VP-81KSi using the front panel buttons, or remotely via:

• RS-485 or RS-232 serial commands transmitted by a touch screen system, PC or other serial controller
• Ethernet over a LAN using a Web browser
  • The SI-1VGA Remote Step-in Panel
• The Kramer RC-IR3 Infrared Remote Control Transmitter or infrared remote extension cable transmitter (optional)
• Remote, contact closure switches

To achieve the best performance:

• Connect only good quality connection cables, thus avoiding interference, deterioration in signal quality due to poor matching, and elevated noise levels (often associated with low quality cables)
• Avoid interference from neighboring electrical appliances that may adversely influence signal quality and position your VP-81KSi away from moisture, excessive sunlight and dust

4.1 Using the IR Transmitter for the VP-81KSi

You can use the RC-IR3 IR transmitter to operate the machine via the built-in IR receiver on the front panel or, instead, via an optional external IR receiver ^1 . The external IR receiver can be located 15m (49ft) away from the machine. This distance can be extended to up to 60m (197ft) when used with three extension cables ^2 .

Before using the external IR receiver, be sure to arrange for your Kramer dealer to insert the internal IR connection cable ^3 with the 3.5mm jack that fits into the REMOTE IR opening on the rear panel. Connect the external IR receiver to the REMOTE IR 3.5mm jack.

5 Installing in a Rack

This section describes the preparation and installation of the unit in a rack.

Before installing in a rack, be sure that the environment is within the recommended range:

OPERATING TEMPERATURE:	0° to +40°C (32° to 104°F)
STORAGE TEMPERATURE:	-40° to +70°C (-40° to 158°F)
HUMIDITY:	10% to 90%, RHL non-condensing

CAUTION!

When installing on a 19" rack, avoid hazards by taking care that:

1. It is located within the recommended environmental conditions, as the operating ambient temperature of a closed or multi unit rack assembly may exceed the room ambient temperature.

2. Once rack mounted, enough air will still flow around the machine.

3. The machine is placed straight in the correct horizontal position.

4. You do not overload the circuit(s). When connecting the machine to the supply circuit, overloading the circuits might have a detrimental effect on overcurrent protection and supply wiring. Refer to the appropriate nameplate ratings for information. For example, for fuse replacement, see the value printed on the product label.

5. The machine is earthed (grounded) in a reliable way and is connected only to an electricity socket with grounding. Pay particular attention to situations where electricity is supplied indirectly (when the power cord is not plugged directly into the socket in the wall), for example, when using an extension cable or a power strip, and that you use only the power cord that is supplied with the machine.

To rack-mount a machine:

1. Attach both ear brackets to the machine. To do so, remove the screws from each side of the machine (3 on each side), and replace those screws through the ear brackets.

Technical line drawing of a mechanical bracket assembly with bolts and mounting holes (no text or symbols)

1. Place the ears of the machine against the rack rails, and insert the proper screws (not provided) through each of the four holes in the rack ears.

Note:

• In some models, the front panel may feature built-in rack ears

- Detachable rack ears can be removed for desktop use

• Always mount the machine in the rack before you attach any cables or connect the machine to the power

- If you are using a Kramer rack adapter kit (for a machine that is not 19"), see the Rack Adapters user manual for installation instructions available from our Web site

• Connect the B (−) pin on the RS-485 port of the PC to the B (−) pin on the RS-485 port on the rear panel of the VP-81KSi
• Connect the G pin on the RS-485 port of the PC to the G pin on the RS-485 port on the rear panel of the VP-81KSi

6.6.1 Setting the RS-485 Machine Number and Bus Termination DIP-switches

This section describes the VP-81KSi DIP-switch settings that determine the RS-485 machine number and bus termination.

Figure 8 illustrates the factory default DIP-switch positions.

Figure 8: RS-485 DIP-switches

Table 3: RS-485 DIP-switch Settings

DIP-switch Number	Function
1, 2, 3	Machine number (see Table 4)Default—All off (up), machine number 1
4	RS-485 Bus TerminationDefault—Off (up)

DIP-switches 1, 2 and 3 determine the RS-485 machine number of the

VP-81KSi. When several VP-81KSi units are connected, the machine number determines the unique identity of the VP-81KSi on the bus (see Table 4).

Note:

• When using a stand-alone VP-81KSi unit, set the machine number to 1 (factory default)
• When connecting more than one VP-81KSi, set the first machine (connected via RS-232) to be machine number 1. The other VP-81KSi units must each be set to a unique machine number between 2 and 16

Table 4: Machine Number DIP-switch Settings

Machine Number	1	2	3
1 (Default)	OFF	OFF	OFF
2	ON	OFF	OFF
3	OFF	ON	OFF
4	ON	ON	OFF
5	OFF	OFF	ON
6	ON	OFF	ON
7	OFF	ON	ON
8	ON	ON	ON

DIP-switch 4 sets the RS-485 bus termination of the VP-81KSi. Only the first and last physical units on the RS-485 bus must be terminated, all others must be unterminated. Moving the DIP-switch up turns the termination off (default), moving the switch down turns the termination on.

6.6.2 Connecting and Controlling Multiple VP-81KSi Devices

You can daisy-chain up to eight VP-81KSi devices with operation via RS-232 from a PC or serial controller.

To daisy-chain up to eight VP-81KSi devices:

1. Connect the RS-232 port ^1 on the first VP-81KSi device to the PC (see Section 6.3).
2. Connect the RS-485 terminal block port on the first device to the RS-485 port on the second device, and so on for all devices.
3. Set the DIP-switches (see Section 6.6.1) as follows:

■ The first device is machine number 1 and the following seven devices are machine numbers 2 to 8
- Terminate the first and last physical devices, that is, in this example terminate machine numbers 1 and 8. Ensure that all other devices are unterminated

6.7 Cascading Multiple VP-81KSi Devices

You can cascade up to eight VP-81KSi devices to build a single “virtual” switcher with up to 57 inputs and one output as illustrated in Figure 9.

To cascade up to eight VP-81KSi devices:

1. Connect the output on the Master VP-81KSi to the video acceptor (for example, a projector).
2. Connect Input 1 on the Master VP-81KSi to the output of the second device.
3. Connect Input 1 on the second VP-81KSi to the output of the third device, and so on for all devices.

Note: Audio connections must follow the same connection scheme as the video connections.

1. Set the DIP-switches (see Section 6.6.1) as follows:

■ The first device is machine number 1 (Master) and the following seven devices are machine numbers 2 to 8
■ Terminate the first and last physical devices, that is, terminate machine numbers 1 and 8. Ensure that all other devices are unterminated

Figure 9: Cascading up to Eight VP-81KSi Devices

Note: The video acceptor must be connected to the Master output. The outputs of all other devices may be connected to any input on the subsequent device.

For operation of cascaded VP-81KSi devices, see Section 7.4.

6.8 Controlling a Remote RS-232 Device

Use the Kramer K-Config software ^1 to define macros sent from the RS-232-2 port to remote RS-232 serial devices (for example, a projector). For instructions on using the K-Config software, see the K-Config software guide.

A computer running the K-Config software can be connected to the VP-81KSi via either the RS-232-1 serial or the Ethernet ports.

You can configure RS-232-2 port command macros to send any data on one of the two possible triggers:

• The “Device startup” trigger. This trigger is generated when one or more signals are detected on any of the inputs and can be used for example, to activate a projector connected to the output of the VP-81KSi
• The “Device inactivity” trigger. This trigger is generated when there is no signal detected on any input during the inactivity timeout period (which is set using the K-Config software to be between 0 and 180 minutes). This trigger can be used for example, to deactivate a projector connected to the output of the VP-81KSi

6.9 Connecting to the VP-81KSi via the Ethernet Port

You can connect the VP-81KSi via the Ethernet in the following ways:

• For direct connection to the PC, use a crossover cable (see Section 6.9.1)

17 Kramer Protocol

Section 17.1 describes how to switch between Protocol 3000 and Protocol ^1 2000. By default, the VP-81KSi is set to protocol 3000 (see Section 17.2) but is also compatible with Kramer's Protocol 2000 (see Section 17.3).

17.1 Switching Protocols

You can switch protocols either via the front panel buttons (see Section 17.1.1) or the protocol commands (see Section 17.1.2).

17.1.1 Switching Protocols via the Front Panel Buttons

To switch from protocol 3000 to protocol 2000 via the:

• Front panel buttons, press the IN 1 and IN 2 button simultaneously
• Infrared remote control transmitter, press the TAKE button and then 13
  To switch from protocol 2000 to protocol 3000 via the:
• Front panel buttons, press the IN 1 and IN 3 button simultaneously
• Infrared remote control transmitter, press the TAKE button and then 16

17.1.2 Switching Protocols via Protocol Commands

To switch from protocol 3000 to protocol 2000, send the following command:

P2000

To switch from protocol 2000 to protocol 3000, send the following command:

0x38, 0x80, 0x83, 0x81

The Windows ^® -based Kramer control software ^1 operates with Protocol 2000. If the VP-81KSi is set to Protocol 3000, it is automatically switched to Protocol 2000.

17.2 Kramer Protocol 3000

This RS-232/RS-485 communication protocol lets you control the machine from any standard terminal software (for example, Windows ^® HyperTerminal Application).

17.2.1 Protocol 3000 Syntax

Host message format:

Start	Address (optional)	Body	Delimiter
#	Destination_id@	message	CR

Simple command (commands string with only one command without addressing):

start	body	delimiter
#	Command SP Parameter_1,Parameter_2,...	CR

Commands string (formal syntax with commands concatenation and addressing):

# Address@ Command_1 Parameter1_1,Parameter1_2,... |Command_2 Parameter2_1,Parameter2_2,... |Command_3 Parameter3_1,Parameter3_2,... |...CR

Device message format:

Start	Address (optional)	Body	Delimiter
~	Sender_id@	message	CR LF

Device long response (Echoing command):

Start	Address (optional)	Body	Delimiter
~	Sender_id@	command SP [param1 ,param2 ...]result	CRLIF

$$ \begin{array}{l} \boxed {\mathbf {C R}} = \text { Carriage return (ASCII 13 = 0x0D) } \ \boxed {\mathbf {L F}} = \text { Line feed (ASCII 10 } = 0 \mathrm{x} 0 \mathrm{A}) \ \boxed {\mathbf {S P}} = \text { Space (ASCII 32 = 0x20) } \ \end{array} $$

17.2.2 Command Part Details

Command:

Sequence of ASCII letters ('A'-'Z', 'a'-'z' and '-'').

Command will separate from parameters with at least single space.

Parameters:

Sequence of Alfa-Numeric ASCII chars ('0'-9', 'A'-Z', 'a'-z' and some special chars for specific commands), parameters will be separated by commas.

Message string:

Every command must to be entered as part of message string that begin with message starting char and end with message closing char, note that string can contain more then one command separated by pipe (") char.

Message starting char:

'#' for host command\query.

'\~' for machine response.

Device address (Optional, for Knet):

Knet Device ID follow by '@' char.

Query sign = '?' , will follow after some commands to define query request.

Message closing char =

Host messages - Carriage Return (ASCII 13), will be referred to by CR in this document.

Machine messages - Carriage Return (ASCII 13) + Line-Feed (ASCII 10), will be referred to by CRLF.

Spaces between parameters or command parts will be ignored.

Commands chain separator char:

When message string contains more than one command, commands will be separated by pipe ( "|").

Commands entering:

If terminal software used to connect over serial \ ethernet \ USB port, that possible to directly enter all commands characters (CR will be entered by Enter key, that key send also LF, but this char will be ignored by commands parser).

Sending commands from some controllers (like Crestron) require coding some characters in special form (like \X##). Anyway, there is a way to enter all ASCII characters, so it is possible to send all commands also from controller.

(Similar way can use for URL \ Telnet support that maybe will be added in future).

Commands forms:

Some commands have short name syntax beside the full name to allow faster typing, response is always in long syntax.

Commands chaining:

It is possible to enter multiple commands in same string by '|' char (pipe).

In this case the message starting char and the message closing char will be entered just one time, in the string beginning and at the end.

All the commands in string will not execute until the closing char will be entered.

Separate response will be sent for every command in the chain.

Input string max length:

64 characters.

Backward support:

Design note: transparent supporting for protocol 2000 will be implemented by switch protocol command from protocol 3000 to protocol 2000, in protocol 2000 there is already such a command to switch protocol to ASCII protocol (#56 : H38 H80 H83 H81).

17.3 Kramer Protocol 2000

This RS-232/RS-485 communication protocol (Version 0.5) uses four bytes of information as defined below. For RS-232, a null-modem connection between the machine and controller is used. The default data rate is 9600 baud, with no parity, 8 data bits and 1 stop bit.

4th byte

1^st BYTE: Bit 7 - Defined as 0.

D - "DESTINATION": 0 - for sending information to the switchers (from the PC);

1 - for sending to the PC (from the switcher).

N5...N0 - "INSTRUCTION"

The function that is to be performed by the switcher(s) is defined by the INSTRUCTION (6 bits). Similarly, if a function is performed via the machine's keyboard, then these bits are set with the INSTRUCTION NO., which was performed. The instruction codes are defined according to the table below (INSTRUCTION NO. is the value to be set for N5...N0).

2^nd BYTE: Bit 7 - Defined as 1.

I6...I0 - "INPUT".

When switching (ie. instruction codes 1 and 2), the INPUT (7 bits) is set as the input number which is to be switched. Similarly, if switching is done via the machine's front-panel, then these bits are set with the INPUT NUMBER which was switched. For other operations, these bits are defined according to the table.

3^rd BYTE: Bit 7 - Defined as 1.

O6...O0 - "OUTPUT".

When switching (ie. instruction codes 1 and 2), the OUTPUT (7 bits) is set as the output number which is to be switched. Similarly, if switching is done via the machine's front-panel, then these bits are set with the OUTPUT NUMBER which was switched. For other operations, these bits are defined according to the table.

4^th BYTE: Bit 7 - Defined as 1.

Bit 5 – Don't care.

OVR - Machine number override.

M4...M0-MACHINE NUMBER.

Used to address machines in a system via their machine numbers. When several machines are controlled from a single serial port, they are usually configured together with each machine having an individual machine number. If the OVR bit is set, then all machine numbers will accept (implement) the command, and the addressed machine will reply.

For a single machine controlled via the serial port, always set M4...M0 = 1, and make sure that the machine itself is configured as MACHINE NUMBER = 1.

NOTES on the above table:

NOTE 1 - When the master switcher is reset, (e.g. when it is turned on), the reset code is sent to the PC. If this code is sent to the switchers, it will reset according to the present power-down settings.

NOTE 2 - These are bi-directional definitions. That is, if the switcher receives the code, it will perform the instruction; and if the instruction is performed (due to a keystroke operation on the front panel), then these codes are sent. For example, if the HEX code

01 85 88 83

was sent from the PC, then the switcher (machine 3) will switch input 5 to output 8. If the user switched input 1 to output 7 via the front panel keypad, then the switcher will send HEX codes:

41 81 87 83

to the PC.

When the PC sends one of the commands in this group to the switcher, then, if the instruction is valid, the switcher replies by sending to the PC the same four bytes that it was sent (except for the first byte, where the DESTINATION bit is set high).

NOTE 3 - SETUP # 0 is the present setting. SETUP # 1 and higher are the settings saved in the switcher's memory, (i.e. those used for Store and Recall).

NOTE 4 - The reply to a "REQUEST" instruction is as follows: the same instruction and INPUT codes as were sent are returned, and the OUTPUT is assigned the value of the requested parameter. The replies to instructions 10 and 11 are as per the definitions in instructions 7 and 8 respectively. For example, if the present status of machine number 5 is breakaway setting, then the reply to the HEX code

0B 80 80 85

would be HEX codes

4B 80 81 85

NOTE 6 – If INPUT is set to 127 for these instructions, then, if the function is defined on this machine, it replies with OUTPUT=1. If the function is not defined, then the machine replies with OUTPUT=0, or with an error (invalid instruction code).

If the INPUT is set to 126 for these instructions, then, if possible, the machine will return the current setting of this function, even for the case that the function is not defined. For example, for a video switcher which always switches during the VIS of input #1, (and its VIS setting cannot be programmed otherwise), the reply to the HEX code

0A FE 80 81 (ie. request VIS setting, with INPUT set as 126dec)

would be HEX codes

4A FE 81 81 (ie. VIS setting = 1, which is defined as VIS from input #1).

NOTE 8 - The reply is as in TYPE 3 above, except that here the OUTPUT is assigned with the value 0 if the setup is not defined / no valid input is detected; or 1 if it is defined / valid input is detected.

NOTE 9 - An error code is returned to the PC if an invalid instruction code was sent to the switcher, or if a parameter associated with the instruction is out of range (e.g. trying to save to a setup greater than the highest one, or trying to switch an input or output greater than the highest one defined). This code is also returned to the PC if an RS-232 instruction is sent while the machine is being programmed via the front panel. Reception of this code by the switcher is not valid.

NOTE 10 - This code is reserved for internal use.

NOTE 13 - This is a request to identify the switcher/s in the system. If the OUTPUT is set as 0, and the INPUT is set as 1, 2, 5 or 7, the machine will send its name. The reply is the decimal value of the INPUT and OUTPUT. For example, for a 2216, the reply to the request to send the audio machine name would be (HEX codes):

7D 96 90 81 (i.e. 128dec+22dec for 2nd byte, and 128dec+16dec for 3rd byte).

If the request for identification is sent with the INPUT set as 3 or 4, the appropriate machine will send its software version number. Again, the reply would be the decimal value of the INPUT and OUTPUT - the INPUT representing the number in front of the decimal point, and the OUTPUT representing the number after it. For example, for version 3.5, the reply to the request to send the version number would be (HEX codes):

7D 83 85 81 (i.e. 128dec+3dec for 2nd byte, 128dec+5dec for 3rd byte).

If the OUTPUT is set as 1, then the ASCII coding of the lettering following the machine's name is sent. For example, for the VS-7588YC, the reply to the request to send the first suffix would be (HEX codes):

7D D9 C3 81 (i.e. 128dec+ ASCII for "Y"; 128dec+ ASCII for "C").

NOTE 14 - The number of inputs and outputs refers to the specific machine which is being addressed, not to the system. For example, if six 16X16 matrices are configured to make a 48X32 system (48 inputs, 32 outputs), the reply to the HEX code

3E 82 81 82 (ie. request the number of outputs)

would be HEX codes

7E 82 90 82

ie. 16 outputs

NOTE 16 - The reply to the "REQUEST WHETHER PANEL IS LOCKED" is as in NOTE 4 above, except that here the OUTPUT is assigned with the value 0 if the panel is unlocked, or 1 if it is locked.

NOTE 19 – After this instruction is sent, the unit will respond to the ASCII command set defined by the OUTPUT byte. The ASCII command to operate with the HEX command set must be sent in order to return to working with HEX codes.

NOTE 24 - Further information needed in instructions 21, 22, 25 and 26 is sent using instruction 42 - which is sent prior to the instruction. For example, to request the audio gain value of right input #9, send hex codes

2A 84 80 81

and then send HEX codes

19 89 81 81.

To set MIX mode, send hex codes

2A 81 84 81

and then send HEX codes

16

NOTE 25 – For units which detect the validity of the video inputs, Instruction 16 will be sent whenever the unit detects a change in the state of an input (in real-time).

For example, if input 3 is detected as invalid, the unit will send the HEX codes

10 83 84 81

If input 7 is detected as valid, then the unit will send HEX codes

10 87 85 81.
