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 a switcher, it resets according to the present power-down settings.
NOTE 2
– These are bi-directional definitions. If the switcher receives the code, it performs the instruction. If the
instruction is performed (due to a keystroke operation on the front panel), then these codes are sent.
For example, if the PC sends HEX code:
01
85
88
83
then the switcher (machine 3) switches input 5 to output 8.
If the user switches input 1 to output 7 using the front panel buttons, the switcher sends HEX code:
41
81
87
83
to the PC.
When the PC sends one of the commands in this group to the switcher, if the instruction is valid, the switcher replies by
sending the same four bytes to the PC that it received (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 that were sent are
returned, and the OUTPUT is assigned the value of the requested parameter. The replies to instructions 10 and 11 are
according to 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 HEX code:
0B
80
80
85
is HEX code:
4B
80
81
85
