3.2 DDC Support
When establishing a VGA connection between a PC or laptop and a display
device, a set of parameters known as EDID is exchanged between them, which
is carried over the DDC channel. In some PC graphic cards and laptops, this
information exchange is essential for proper VGA OUT operation.
3.3 Defining EDID
The Extended Display Identification Data (EDID1) is a data-structure,
provided by a display, to describe its capabilities to a graphics card (that is
connected to the display’s source). The EDID enables the PC or laptop to
“know” what kind of monitor is connected to the output. The EDID includes
the manufacturer’s name, the product type, the timing data supported by the
display, the display size, luminance data and (for digital displays only) the
pixel mapping data.

7.6 Choosing the Audio-Follow-Video or Breakaway Option
You can switch stereo audio signals in one of two ways, either:
Audio-follow-video (AFV), in which all operations relate to both the
video and the audio channels; or
Breakaway, in which video and audio channels switch independently
7.6.1 Setting the Audio-Follow-Video Option
To set the Audio-follow-video (AFV) option, press the AFV button:
If the AUDIO and VIDEO configurations are the same, then the AFV
button illuminates. The audio follows the video.

The VP4x8AK output audio signal level1 is shown on the REL. AUDIO
LEVEL 7-segment display.
The factory default audio gain is set to 0dB. An audio gain value of 0dB
indicates that the output signal value is identical to the input signal value.
When increasing/decreasing the audio gain, the output signal level is
higher/lower than the input signal level.
Gain level values are relative since the audio input signal can be also
adjusted, while the range of the output gain remains constant1, independent of
the input level adjustment.
8 Flash Memory Upgrade
The VP4x8AK uses a microcontroller that runs firmware located in FLASH
memory.
The latest version of firmware and installation instructions can be
downloaded from the Kramer Web site at www.kramerelectronics.com.

Kramer Protocol
By default, the VP-4x8AK is set to protocol 3000 (see Section 14.2) but is
also compatible with Kramer’s Protocol 2000
(see Section 14.3).
Section 14.1 describes how to switch between protocol 3000 and protocol
2000.
14.1 Switching Protocols
You can switch protocols either via the front panel buttons (see
Section 14.1.1) or the protocol commands (see Section 14.1.2).
14.1.1 Switching Protocols via the Front Panel Buttons
To switch from protocol 3000 to protocol 2000, press and hold2 the OUT 1
and OUT 2 buttons for a few seconds.
The display shows 2000.
To switch from protocol 2000 to protocol 3000, press and hold the OUT 1
and OUT 3 buttons for a few seconds.
The display shows 3000.
14.1.2 Switching Protocols via Protocol Commands
To switch from protocol 3000 to protocol 2000, send the following command:
#P2000<CR>
To switch from protocol 2000 to protocol 3000, send the following command:
0x38, 0x80, 0x83, 0x81
The Windows®-based Kramer control software3 operates with protocol 2000. If
the VP-4x8AK is set to protocol 3000, it is automatically switched to protocol
14.2 Kramer Protocol 3000
This RS-232/RS-485 communication protocol lets you control the machine
from any standard terminal software (for example, Windows®
You can download our user-friendly “Software for Calculating Hex Codes for Pr otocol 2000” from the technical support

parity, 8 data bits, and 1 stop bit.
14.2.1 Protocol 3000 Syntax
Host message format:
Simple command (commands string with only one command without
addressing):
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:
Device long response (Echoing command):
CR = Carriage return (ASCII 13 = 0x0D)
LF = Line feed (ASCII 10 = 0x0A)
SP = Space (ASCII 32 = 0x20)
14.2.2 Command Parts 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).

as defined below. The default data rate is 9600 baud, with no parity, 8 data
bits and 1 stop bit.
Table 17: Protocol Definitions
1st byte
2nd byte
3rd byte
4th byte
1st 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).
2nd 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.
3rd 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.
4th 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).

52
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 h ere 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 22 and 25, is sent using instruction 42 – which is sent prior to the
instruction. For example, to request the audio gain value of output # 9, send hex codes
2A 81 80 81
and then send HEX codes
19 89 81 81.
To set input gain change mode, send hex codes
2A 80 80 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.
