3.3.1 Self Test Function

The purpose of this test is to make sure the communication from host PC
to ADAM-4570W/4571W is OK. If there is still an error, you can check
the communication from the ADAM-4570W/4571W to the serial devices.
If the test is selected, an external test will be done to check that the con-
nection signals for each port are working properly. For the test, you will
need to connect each port to a loopback tester (provided in the package).
The loopback test only applies to RS-232 mode. The test is divided into
two parts: Signal test and Communication Parameters test.
