Table 5: Instruction Codes For Protocol 2000 - Kramer VS-81H User Manual

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.
Note: All values in the table are decimal, unless otherwise stated.

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
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
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
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
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
NOTE 15 – When the OVR bit (4
1 (SWITCH VIDEO) will cause all units (including audio, data, etc.) to switch. Similarly, if a machine is in "FOLLOW"
mode, it will perform any "video" instruction.
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.
