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 5
– For the OUTPUT byte set as 6, the VIS source is the input selected using the OUTPUT byte Similarly, for the
OUTPUT byte set as 7, the VIS source is the output selected using the OUTPUT byte Note also, that on some machines the
sync source is not software selectable, but is selected using switches, jumpers, etc!
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
