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 performs the instruction, and if the
instruction is performed (due to a keystroke on the front panel), then these codes are sent. For example:
0000 0001
1000 0101
1000 1000
0011
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:
0100 0001
1000 0001
1000 0111
1000 0011
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 sent (except for the first byte, where the DESTINATION bit is set "high").
