Operation
Note
In the reading mode, the CLV does not output the contents of the polling reflector.
Triggering the reading pulse via the terminal emulator
In the default setting, the "Sensor 1" switching input is the (external) trigger source of the
reading pulse. For test purposes the reading pulse can also be triggered directly via the
terminal emulator of CLV Setup. To do so, a different trigger source must be selected
temporarily in the CLV.
