NETWORK CONFIGURATION
The CLV can be used as part of a multidrop network of bar code reading stations which communicate with a host device as
shown in Figure 2-6. Using an RS 485 bus consisting of a two-conductor cable, the system can address up to 31 devices. The
SICK CLX 200 Network Controller is used to organize data and control polling.
