Functional principle of the external digital 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 outputs “Aux Out 1” and “Aux Out 2” in the connection mod‐
ule.
