For a single machine controlled via the serial port, always set M4…M0 = 1, and make sure that the machine itself is
configured as MACHINE NUMBER = 1.

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 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 the
HEX code
01 82 81 81
was sent from the PC, then the switcher (machine 1) will switch input 2 to output 1. If the user switched input 1 to output 2
via the front panel keypad, then the switcher will send HEX codes:
41 81 82 81
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 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 reply to instruction 11 is as per the
definitions in instruction 8. For example, if the present status of machine number 1 is breakaway setting, then the reply to the
HEX code
0B 80 80 81
would be HEX codes
4B 80 81 81
