3. Select Port > Send Test Data. The program sends out a repeating data stream.
Note: To stop the data stream, select Send Test Data again.
• If the loopback plug is in place and the port is working correctly, the test
data should be echoed back to the screen.
• If the loopback plug is not in place or the port is not working correctly, no
data or garbled data is echoed back to the screen.
Note: If no characters appear, try putting the loopback plug on an adjacent
port. It may be that you have the ports mixed up.
4. If further testing is required, select Port > Loopback Test.
If the loopback plug is in place and the port is working correctly, the system
should return the message “Passed.”
If the loopback plug is not in place or the port is not working correctly, the
system will return the message “Failed.”
5. If the port has failed in Step 4, and the RocketPort is equipped with an
external interface box or fanout cable, click the loop button to switch the
internal loopback feature on.
6. Repeat Steps 3 and 4. If the port now passes the tests, the fault may lie in the
interface box or fanout cable. Contact Comtrol technical support for more
assistance.
7. If you are finished testing ports, close the Test Terminal and restart the
applications.
