Installing in a Rack
This section provides instructions for rack mounting the unit.
Before Installing in a Rack
Before installing in a rack, be sure that the
environment is within the recommended range:
OPERATING TEMPERATURE:
0º to +55ºC (32º to 131ºF)
STORAGE TEMPERATURE:
-45º to +72ºC (-49º to 162ºF)
HUMIDITY:
10% to 90%, RHL non-condensing
!
How to Rack Mount
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.
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.
VP-4x4K - Installing in a Rack
2. 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

Storing/Recalling Input/Output Configurations
You can store and recall up to eight input/output setups using the four SELECTOR
IN and the four SELECTOR OUT buttons, as Figure 11 illustrates. For example,
setup 2 is stored and can be recalled in OUT 1 and setup 7 is stored in IN 3.
The 8 input/output configurations (or setups) also include the relevant audio-followvideo/breakaway option definition.
When operating via the embedded Web page (see Section 8), RS-232 communication or the
IR remote control transmitter, you can store/recall up to 16 setups.
The gray numbers (1 to 8) in Figure 11 that illustrate the corresponding store/recall
configuration number, are for the purpose of illustration only and do not actually appear on the

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 software (not as part of a switching
operation) operates with Protocol 2000. If the VP-4x4K is set to Protocol 3000, it is
automatically switched to Protocol 2000.

13.2.2
Command Terms
Command
A sequence of ASCII letters ('A'-'Z', 'a'-'z' and '-').
Command and parameters must be separated by at least one space.
Parameters
A sequence of alphameric ASCII characters ('0'-'9','A'-'Z','a'-'z' and some special
characters for specific commands). Parameters are separated by commas.
Message string
Every command entered as part of a message string begins with a message
starting character and ends with a message closing character.
Note: A string can contain more than one command. Commands are separated by
a pipe ( '|' ) character.
Message starting character
'#' – For host command/query
'~' – For machine response
Device address (Optional when directly connected to the device)
K-NET Device ID or MACHINE NUMBER followed by '@'
(ex. #02@CRLF )
Query sign
'?' follows some commands to define a query request.
All outputs sign
'*' defines all outputs.
Message closing character
CR – For host messages; carriage return (ASCII 13)
CRLF – For machine messages; carriage return (ASCII 13) + line-feed (ASCII 10)
Command chain separator character
When a message string contains more than one command, a pipe ( '|' ) character
separates each command.
Spaces between parameters or command terms are ignored.
44
VP-4x4K - Kramer Protocol
13.2.3
Entering Commands
You can directly enter all commands using a terminal with ASCII communications
software, such as HyperTerminal, Hercules, etc. Connect the terminal to the serial,
Ethernet, or USB port on the Kramer device. To enter CR , press the Enter key.
( LF is also sent but is ignored by command parser).
For commands sent from some non-Kramer controllers like Crestron, some
characters require special coding (such as, /X##). Refer to the controller manual.
13.2.4
Command Forms
Some commands have short name syntax in addition to long name syntax to allow
faster typing. The response is always in long syntax.
13.2.5
Command Chaining
Multiple commands can be chained in the same string. Each command is
delimited by a pipe character ( '|' ). When chaining commands, enter the message
starting character and the message closing character only once, at the beginning
of the string and at the end.
Commands in the string do not execute until the closing character is entered.
A separate response is sent for every command in the chain.
13.2.6
Maximum String Length
64 characters.
13.2.7
Backward Support
Protocol 2000 is transparently supported by Protocol 3000. You can switch
between protocols using a switch protocol command from either platform.

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 (i.e. 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 (i.e. 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).
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 (i.e. request VIS setting, with INPUT set as 126dec)
would be HEX codes
4A
FE
81
81 (i.e. 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 (i.e. request the number of outputs)
would be HEX codes
7E
82
90
82
i.e. 16 outputs
54
VP-4x4K - Kramer Protocol
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 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
