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 resets 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 operation on the front panel), then these codes are sent. For example, if
the HEX code
01 85 88 83
was sent from the PC, then the switcher (machine 3) switches input 5 to output 8. If the user switched input 1 to output 7
via the front panel keypad, then the switcher sends HEX codes:
41 81 87 83
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 was sent (except for the first byte, where the DESTINATION bit
is set high).
NOTE 3 - SETUP # 0 is the present setting. SETUP # 1 and higher are the settings saved in the switcher's memory, (i.e.
those used for Store and Recall).
NOTE 4 - The reply to a "REQUEST" instruction is as follows: the same instruction and INPUT codes as were sent are
returned, and the OUTPUT is assigned the value of the requested parameter. The replies to instructions 10 and 11 are
as per the definitions in instructions 7 and 8 respectively. For example, if the present status of machine number 5 is
breakaway setting, then the reply to the HEX code
0B 80 80 85
would be HEX codes
4B 80 81 85
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.
