Basic test of communication port on the Carrier DataLink, as accessed by the Network 8000 SIM-CCN.

Issue

Basic test of communication port on the Carrier DataLink, as accessed by the Network 8000 SIM-CCN.

Product Line

TAC I/A Series

Environment

Carrier DataLink communication gateway to a bus with CCN controllers

Network 8000 SIM-CCN (Systems Integration Module for Carrier Comfort Network)

Terminal emulator, such as HyperTerminal

Cause

In some cases it is necessary to verify that third-party equipment is functional, independent of the SIM-CCN.

Resolution

  1. Unplug the serial cable from the SIM, leave the other end connected to the Carrier  DataLink.
  2. Set up HyperTerminal: 8 data bits, no parity, 1 stop bit, 9600 baud, no flow control.
  3. Type " RT 1 DPTCONFG",  expect a "?" prompt.  If a prompt is returned, the port on the DataLink is functional; if no prompt is returned, the port may not be functional.
  4. If necessary, change the baud rate used by the terminal emulator to 300, 1200, 2400, or 4800 bits per second and repeat the test step 3. If the test fails at all of the possible baud rates supported by the DataLink, the port may not be functional.
