Table 5: Instruction Codes for Protocol 2000
Note: All values in the table are decimal, unless otherwise stated
INSTRUCTION DEFINITION FOR SPECIFIC INSTRUCTION NOTE
# DESCRIPTION INPUT OUTPUT
1 SWITCH V DEO Set equal to video input
which is to be switched
(0 = disconnect)
Set equal to video output which is
to be switched
(0 = to all the outputs)
2
61
IDENTIFY MACH NE
1 - video machine name
3 - video software version
9 - protocol 2000 version
0 - Request first 4 digits
1 - Request first suffix
2 - Request second suffix
3 - Request third suffix
10 - Request first prefix
11 - Request second prefix
12 - Request third prefix
13
62 DEFINE MACHINE 1 - number of inputs
2 - number of outputs
1 - for video
2 - for audio

NOTES on the above table:
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 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 22dec for 2nd byte, and 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 3dec for 2nd byte, 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 ASCII for “Y”; 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
