Communication Tests
NOTE:
These tests are only applicable to units
that are equipped with the M-3931 HMI
Module.
COM1 and COM2 Test
The
COM1
and
COM2
LOOPBACK TESTS
allow
the user to test the front and rear RS-232 ports
for proper operation. These tests require the use of
a loop-back plug (see Figure 6-5).
The loopback plug consists of a DB9P connector
(male) with pin 2 (RX) connected to pin 3 (TX) and
pin 7 (RTS) connected to pin 8 (CTS). No other
connections are necessary.
