Test

The purpose of this test is to confirm that the communication from the

host PC to the EDG device is OK. When the test is selected, an external

test will be performed to check that the connection signal between each

port is working properly. For this test, you will need to connect each port

to a Loopback tester. Refer to the following chart for specifications of this

Loopback tester. The Loopback test only applies to RS-232 mode. It is

divided in two parts: Signal test and Communication Parameters test.

1. Click on the Test button in the Port Mapping utility. A message

will confirm that the loopback connector have already been con-

nected with the EDG COM port. If ready, click the Start button to

start the test.

Test Fail (Without Loopback Connector)
