3.4.1.1 Communications Diagnostic Port Loop-back Test
WINDIAG’s Communications Diagnostic Menu (see Figure 3-13) provides for selection of
the communication port to be tested (1 through 5). Depending on the type of network (RS-
232 or RS-485) and the port in question, a special loop-back plug is required as follows:
Ports 1, 2, 4, & 5 use the 9-pin female D-type (RS-232) loop-back plug.
RS-485 operation of Port 3 - use a 9-pin female D-type (RS-485) loop-back plug.
RS-232 operation of Port 3 - use a 9-pin female D-type (RS-232) loop-back plug
See Figure 3-16 for wiring of Female D-Type Loop-back Plugs.
This group of tests verifies the correct operation of the Communication Interface. COM1,
COM2, COM3, COM4 and COM5 can be tested with this diagnostic. The ControlWaveLP
communication port that is connected to the PC (local or network and used for running
these tests) can’t be tested until diagnostics has been established via one of the other ports,
i.e., to test all ControlWaveLP communication ports (via WINDIAG), communications
with the PC will have to be established twice (each time via a different port). It should be
