6-3 Connections

Connecting to a Bar Code Reader via RS-232C

The connection examples in this section show only the basic connection dia- grams. We recommend that appropriate noise countermeasures be taken in ac- tual applications, including the use of shielded twisted-pair cables. Refer to 2-3 Wiring for actual wiring methods.

The following diagram shows the connections between an OMRON V500-se- ries Bar Code Reader and the RS-232C port on the Serial Communications Board.
