Kramer Protocol 2000
8 Kramer Protocol 20001
The VP-2x2 is compatible with Kramer’s Protocol 2000 (version 0.50)
(below). This RS-232/RS-485 communication protocol 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.

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 82 81 81
was sent from the PC, then the switcher (machine 1) will switch input 2 to output 1. If the user switched input 1 to output 2
via the front panel keypad, then the switcher will send HEX codes:
41 81 82 81
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 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 reply to instruction 11 is as per the
definitions in instruction 8. For example, if the present status of machine number 1 is breakaway setting, then the reply to the
HEX code
0B 80 80 81
would be HEX codes

Table of Hex Codes for Serial Communication
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.
NOTE 12 - Under normal conditions, the machine's present status is saved each time a change is made. The "power-down"
save (auto-save) may be disabled using this code. Note that whenever the machine is turned on, the auto-save function is set.
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 or
2, the machine will send its name. The reply is the decimal value of the INPUT and OUTPUT. For example, for a VP-2x2, the
reply to the request to send the audio machine name would be (HEX codes):
7D 82 82 81 (i.e. 128dec+ 21dec for 2nd byte, and 128dec+ 2dec 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).
NOTE 14 - The number of inputs and outputs refers to the specific machine which is being addressed, not to the system.
