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.
