This section provides connection examples and corresponding connection diagrams.
Refer to A-4-3 Applicable Connectors and Recommended Cables for actual wiring methods.
Note Connections to a computer running the CX-Programmer are the same as those shown here.
z 1:1 Connections via RS-232C Port
Note The maximum cable length for an RS-232C connection is 15 m. RS-232C communications specifications,
however, do not cover transmissions at 19.2 Kbps. Refer to documentation of the device being connected
when using this baud rate.
