CJ-series Serial Communications Units Operation Manual for NJ-series CPU Unit(W494)

Precautions for Safe Use

The signal names SDA/B and RDA/B do not always have the same polarity as that shown above.
Check the polarity of the external device before you make connections.

Additional Information

The RS-422A/485 port on the CJ1W-SCU32/42 has a failsafe function built into the receiver to
prevent reading incorrect signals when the RDA and RDB pins are open or shorted.

When you mount the Serial Communications Unit, make sure to provide space for the mounting height
and connector cover dimensions shown below.

Note

The mounting heights shown above are applicable when the attached connectors, connector
covers, and recommended cables are used. The mounting height may differ when other connec-
tors, connector covers, and cables are used. Take into account the connectors, connector cov-
ers, and the minimum bending radius of the cables to determine the mounting height.
