Connecting supply voltage
When wiring the bar code scanner using connection module CDB620 or CDM420, the bar
code scanner's data and function interfaces are contacted to the connection module to-
gether with the power supply.
1. Ensure that the connection module's supply voltage has been switched off.
2. Standard version: Connect the bar code scanner's 15-pole cable plug to the connection
module's 15-pole socket and screw it tight.
- or -
Ethernet version: Connect the bar code scanner's 12-pole plug via a corresponding ca-
ble (e.g. 2042916) to the connection module's 15-pole socket and screw it tight.
6.4.2 Wiring serial data interfaces
The maximum data transfer rate depends on the cable length and the interface type.
