Operation
B. CLV integrated in Omni Portal System
B1. Start/Stop mode
Prerequisites:
• One object in the reading field per reading interval.
Example: omni-directional 2-side reading with 4 CLVs (slaves) and OTC 400 controller
(master)
• Minimum object distance > size of reading field
(size of reading field = distance between sensors for start and stop of reading trigger)
• Dynamic focus control according to application:
– with OTS height information (distance) via CAN bus for reading from top
– one distance configuration (fixed focus) for e. g. reading from side and sufficient
depth of field (DOF)
• Two reading trigger sensors connected to OTC 400 (start and stop)
• Master/slave arrangement using the CAN interface
Possible reading triggers:
• via OTS trigger
Further preparations for each CLV:
¾ Configuring oscillating mirror (optional):
see Chapter c) Optional: Parameterizing oscillating mirror functions, Page 6-10
¾ Configuring no. of bar codes to be read:
see Chapter f) Parameterizing the evaluation characteristics, Page 6-23
Note To separate bar codes of the same type with identical contents, connect an incremental
encoder to the OTC 400 and activate the "Compare Code Position" function in the CLV.
See also Chapter f) Parameterizing the evaluation characteristics, Page 6-23.
