EtherNet Port Test
You can do a loop back test on the Twisted Pair (RJ45) EtherNet connector. To perform this test you need a
special RJ45 Loop back cable connected to your RouteFinder. Refer to Appendix A for cable specifications.
WAN Port Test
The WAN port can be tested in synchronous or asynchronous mode.
To test the WAN port in Synchronous mode, select the port and then click on the Perfom Tests button to
initiate the test. Results of the test will be displayed after a while.
Note: In case of an error message during this test, make sure that you have connected a DSU in loop back
mode to the correct WAN port. You will also be able to see the Send Data and Receive Data indicators blink
during the test. Since the RouteFinder expects an external clocking device during synchronous operation, it is
not possible to conduct this test without a synchronous DCE.
To test a WAN port in Asynchronous mode, either an asynchronous RS-232 Loop-back cable or a modem
having loop-back mode is needed. Also in this mode, you need to choose the baud rate at which the test has
to be performed. If you are using a modem in loop-back mode, refer to the modem user manual for defails on
setting it up. Modems support various loop-back modes like local digital, local analog, remote digital and
remote analog. You may choose Local Digital for testing the WAN port.
Once the loopback is setup, you should choose the WAN port and baud rate and then click on Perform Test.
If an error occurs, check your loopback setup once again.
WAN Link Test
Since the Setup software does a loopback test (sends a pattern and expect to receive the same pattern), it can
be used to test the RouteFinder hardware port and also the actual communicaiton link used for routing.
Also, on leased lines you can test the entire link and the remote DCE by putting remote DCE in loopback
mode. Consult the user manual of the DCE for doing this.
Certain modems support remote analog and digital loop-back modes. If you are using these types of modems
you can conduct link tests on Dial up lines. Consult you modem owner's manual for this.
