Allows loopback test. The UDC goes into
Loopback mode in which it sends and receives its
own message. The UDC displays PASS or FAIL
status in the upper display and LOOPBACK in
the lower display while the test is running. The
UDC will go into manual mode. The test will run
until the operator disables it here, or until power
is turned off and on.
The UDC does not have to be connected to the
RS-485 link to perform this test. If it is connected,
only one UDC2300 should run the loopback test
at a time. The computer should not be
transmitting on the link while the loopback test is
active.
