• The connectors attached to the used electrical connections of the Ethernet version
have to be firmly screwed.
The same applies to the EMC requirement (ESD) according to CE.
Depending on the device version, the following electrical connections are available at the
bar code scanner:
Tab. 6-1: Electrical connections to the bar code scanner with a fixed cable and connector
(standard version)
Tab. 6-2: Electrical connections to the bar code scanner with connector unit (Ethernet version)
Important Additional digital inputs and outputs are available at connection module CDB620/CDM420
(available from week 07/2008) in combination with the parameter memory module
CMC600.
