Wiring the NX1W-CIF01 Serial Communications Option Board
This section explains the wiring of an NX1W-CIF01 Serial Communications Option Board.
Caution
When you connect a computer or other peripheral device to a Controller that has a
non-isolated DC power supply, either ground the 0-V side of the external power supply
or do not ground it at all.
If the peripheral devices are grounded incorrectly, the external power supply may be
short-circuited. Never ground the 24-V side of the power supply, as shown in the fol-
lowing figure.

Recommended RS-232C Wiring
We recommend the following wiring method for the RS-232C, especially in environments prone to
noise.
1
Use shielded twisted-pair cables for the communications cables.

2
Combine a signal wire and SG (signal ground) wire in a twisted-pair cable. At the same time,
bundle the SG wires at the connectors on Option Board and the remote device.
3
Connect the SHLD of the communications cable to the SHLD on the Option Board.
