Connect the switch as shown in b)
Serial Aux
(RS-232)
Function assignment to "External input 2" via SOPAS:
- Start of reading clock
- Stop of reading clock
- Start teach-in matchcode/start code comparison
- if required further functions in the future
Ratings for "External input 2"
("In 2“ switching input)
Power fed to the input starts the
assigned function, e.g. stop of reading
clock.
(default setting: logic not inverted
[active high], debouncing 10 ms)
– Optodecoupled, reverse polarity
protected
– Can be wired with the PNP output of
a sensor

Software-controlled, the CMC600 transfers the
switching status of its physical "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“.
"External

Switch S3: 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).
