RS-232 Control Commands:
1) In the table below, “a” represents Input and “b” represents Output. The number value range of “a” and “b” depends on
the number of inputs and outputs of the controlled matrix. If out of range, it is considered a command input error, and the
unit will not execute the command.
2) Please note there is a punctuation mark “.” at the end of every command. This cannot be omitted.
3) Note the uppercase and lowercase letters.
