WEB/CP-202-XPR AND WEB/CP-602-XPR CONTROLLERS
For both local and remote I/O, each input or output used requires a special Niagara
added in the station database. These components act as the station interface to the physical I/O points. The Nrio points you need
for each input or output type are noted in previous wiring sections in boldface.
For Nrio software details, see the NiagaraAX NRIO Guide in Workbench online Help, or the same document in PDF.
COMMUNICATIONS WIRING
Communications ports on the controller are alongside the edge of the controller board, accessible with the right cover removed
(Fig. 15). Communications port types include Ethernet and Serial.
NOTE: Prior to connecting cables, provide strain relief for them to prevent damage to the controller.

Ethernet
Two, female 10/100 Mbps Ethernet connections are provided on the controller. These are RJ-45 connectors labeled PRI and
SEC. Use a standard Ethernet patch cable for connecting to a hub or Ethernet switch.
The controller's factory-default IP address for PRI (NET1) is
matches the last digit in the controllers's serial number, and the subnet mask is
By default, SEC (NET2) on the unit is disabled.
Refer to the JACE NiagaraAX Install and Startup Guide for details on changing IP address.
NOTE: Typically, you only use PRI (primary port), unless you have a specific application for isolating a driver's network traffic to
a separate LAN, using SEC. Do not use SEC as the primary port.
Serial
There are two "RS" serial ports on the controller's base board. Each has a UART capable of operation up to 115,200 baud.
• An RS-232 port uses an RJ-45 socket connector, and operates as COM1.
• An isolated RS-485 port is on three terminals of a 6-position screw-terminal connector, and operates as COM2 (by default).
