Connecting the Cables
RS-422 communication allows connection between a PT and PC via a Link Adaptor using RS-232C and RS-422
cables.
The method of connection differs depending on whether the unit has an RS-232C connector or RS-422 connector
Note 1. Ground the PC unit FG terminal to Class 3 ground. Refer to the appropriate PC Installation Guide for
Connecting Units with an RS-232C Connector
The diagram below shows the connection of a PC and PT using an RS-422 cable and two Link Adaptors. The
connection from the PT and PC to the Link Adaptor is by means of an RS-232C cable.
Connecting Units with an RS-422 Connector
Some types of PC unit have an RS-422 connector. An RS-422 cable can be connected directly to this connector.
About the Cables
RS-232C Cable
Versions of RS-232C cable are available with the following connector combinations:
If a cable more than 2 m long is required, refer to Appendix 3C RS-232C Connections for details on how to make
one.
RS-422 Cable
OMRON does not provide RS-422 cables. Refer to this Appendix if an RS-422 cable is required.
