Serial port external loopback connectors
The self-test external loopback tests confirm that the serial ports are working
correctly. To conduct this test you need to fit special test plug connectors to each
of the serial ports. The test connectors are wired to feed back the transmitted
output as a receiver input. Tab. 39 identifies the wiring requirements for each of the
test plug connectors.

To fully test the serial ports that are wired for both RS-232 and RS-422, you need
two separate external loopback tests that use different loopback connectors, as
shown in Tab. 40.
