Functional principle of the external switching outputs
The device outputs the output states of its logical outputs “External output 1” and
“External output 2” via its serial Aux interface. By means of a software-controlled opera‐
tion, the CMC600 automatically adopts the states via the connecting cable and sets
them on its physical digital switching outputs “Aux Out 1” and “Aux Out 2” in the con‐
nection module.
