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 8 - The reply is as in TYPE 3 above, except that here the OUTPUT is assigned with the value 0 if the setup is not

defined / no valid input is detected; or 1 if it is defined / valid input is detected.

NOTE 9 - An error code is returned to the PC if an invalid instruction code was sent to the switcher, or if a parameter

associated with the instruction is out of range (e.g. trying to save to a setup greater than the highest one, or trying to

switch an input or output greater than the highest one defined). This code is also returned to the PC if an RS-232

instruction is sent while the machine is being programmed via the front panel. Reception of this code by the switcher is

not valid.
