Rj45 Rs-485 Test Cable; Connecting Rj45 Devices - Pepperl+Fuchs ICDM-RX/TCP-DB9/RJ45-PM Installation And Configuration Manual

ICDM-RX/TCP Installation and Configuration Guide

RJ45 RS-485 Test Cable

• Pins 4 to 5
• Pins 1 to 8
• Pins 2 to 6 to 7
Note: You can use Test Terminal in PortVision DX
(Windows) or minicom (Linux) to test the serial
port. You can refer to Testing Ports Using Test
Terminal on Page 134 for Windows systems.
7.2.5. RJ45 RS-485 Test Cable
You can use a straight-through cable as illustrated previously, or build your own cable.
Note: RS-422 pin outs are not standardized. Each peripheral manufacturer uses different pin outs. Please
refer to the documentation for the peripheral to determine the pin outs for the signals above.

7.2.6. Connecting RJ45 Devices

You can use this information to connect serial devices to RJ45 connectors.
1. Connect your serial devices to the appropriate serial port on the ICDM-RX using the appropriate cable.
Note: Refer to the hardware manufacturer's installation documentation if
you need help with connector pin outs or cabling for the peripheral
device.
2. If the ICDM-RX has RX/TX LEDs, verify that the devices are communicating
properly.
The RX (yellow) and TX (green) LEDs function accordingly when the cable is
attached properly to a serial device.
• After power cycling the ICDM-RX, the RX/TX LEDs are off.
• The LEDs do not function as described until the port has been opened by an application. You can use
Test Terminal in PortVision DX to open a port or ports if you want to test a port or ports (Testing Ports
Using Test Terminal on Page 134).
