PortVision DX for Windows or Minicom for Linux) to test serial ports.
Wire the terminals together to create a loopback.
• TxD to RxD
• RTS to CTS to RI
• DTR to CD to DSR
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.

7.4.6. Connecting Serial Devices

Use the following information to connect the ICDM-RX with serial terminals.
1. Connect your serial devices to the appropriate serial port on the ICDM-RX using the appropriate cable. You
can build your own cables or loopbacks using the appropriate discussions.
Note: Refer to the hardware manufacturer's installation documentation if you need help with connector pin
outs or cabling for the serial device.
