POWER SUPPLY CONNECTIONS
The CLV requires a power source of 5 V DC to 30 V DC. Current requirement for the CLV is 100 mA. Power supplies suitable
for the CLV include:
1. Power supply from SICK Optic-Electronic, Inc.
2. Another power supply provided by the customer. This power supply must meet the following specifications:
The 24 V DC output circuit must be isolated from the input circuit by double insulation and an isolating transformer. (Ref. IEC 742
and DIN / VDE 0551.)
Output voltage:
5 V DC ± 5% to 30 V DC ± 20%
Power output:
minimum 15 VA
Current output:
peak current maximum 1 A/continuous current minimum 500 mA
PHYSICAL CONFIGURATIONS OF SCANNERS
Host communication configurations include: point-to-point, daisy-chain (master/slave or pass-through), and network (RS 485
multidrop).
POINT-TO-POINT CONFIGURATIONS
In a point-to-point configuration, the CLV is connected directly to the host device via a power supply distribution unit. Figure 2-5
shows both of these point-to-point configurations. Functions include:
• Transmission of decoded bar code information from CLV to host
• Transfer of selected diagnostic reading data from CLV to host
• Relay of error strings from CLV to host
• Trigger of reading gate from host to CLV
• Programming and operation via command strings from host to CLV
