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.
