Software-controlled, the CMC600 transfers
the switching status of its physical "Aux In 1"
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 1“.
"External
input 1"
Power fed to the input starts the
assigned function, e.g. start of
reading clock.

Switch S6: SGND-GND
ON: GND of the sensor connected to GND
of CDB620/CMC600.
OFF: GND of the sensor connected to
SensGND of CDB620/CMC600
(Sensor connected electrically isolated
to the CDB620/CMC600).
