Software-controlled, the CMC600 transfers the
switching status of its physical "Aux In 2" input
automatically via the cable to the serial Aux
data interface of the CLV61x.
The CLV61x converts the status internally to its
logical "External input 2“.

Power fed to the input starts the
assigned function, e.g. stop of reading
clock.

OFF: GND of the sensor connected to
SensGND of CDB620/CMC600
(Sensor connected electrically isolated
to the CDB620/CMC600).
