Operation
Parameterizing reading trigger in the CLV490:
Parameterizing slave mode in the CLV490:
Note
When in slave mode, the CLV490 receives the trigger signals for the reading pulse (start and
stop) from the OTC400 via the CAN bus along with (depending on the parameter settings)
the distance information required for focus position switchover/autofocus. The distance
information can be generated, for example, by the OTC400 by means of height-control
photoelectric switches or can originate from another CLV490, which forwards its distance
measurements.
The CLV490 sends the reading result (bar code contents) to the OTC400 via the bus as
soon as the bar code(s) have been successfully read. The OTC400 compiles the results
received from all the slaves and evaluates them accordingly before sending them to the
host.
