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:
0000 0001
Instruction “Switch Groups”
1000 0010
Input #2
1000 0001
in composite video group
1000 0001
Machine #1 (master)
Was sent from the PC, then the switcher (machine #1) will switch input 2 in composite video group to its output. If the
user switched input 4 in the VGA group via the front panel keypad, then the switcher will send:
0100 0001
1000 0100
1000 0100
1000 0001 to the PC.
When the PC sends instruction #1 or #2 to the switcher, then, if the instruction is valid, the switcher replies by sending
the same four bytes to the PC that were sent (except for the first byte, where the DESTINATION bit is set high).
