3.4.1.2 COM 1, 2, 3, 4 & 5 External Loop-back Test Procedure
1. Connect an external loop-back plug to the CPU Port to be tested, i.e., J1 for Port 1, J2 for
Port 2, J3 Port 3, or J4 for Port 4 and J5 for Port 5 (see Figures 3-12 and 3-13).
2. Type "1," "2," "3," "4" or "5" for the port to test.
3. Set baud rate to test to 115200 baud or ALL ASYNC and the number of passes to 5.
4. Click on RUN button next to External loop-back.
 Test responses:
a) Success - All sections of test passed
b) Failure - TXD RXD Failure
- CTS RTS Failure
 Execution time < 5 sec.
3.4.1.3 Ethernet Diagnostic Port Test
WINDIAG’s Ethernet Diagnostic Menu (see Figure 3-15) provides for selection of the
Ethernet communication port to be tested (1). A special loop-back plug is required to
perform the Ethernet loop-back test (see Figure 3-14).
Figure 3-14 - RJ-45 Ethernet Loop-back Plug
If the ControlWaveLP Ethernet port is connected to the PC (and used for running these
tests), it 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
noted that the ControlWaveLP communication port that is connected to the PC (RS-232 or
RS-485) must be good for WINDIAG to run the Ethernet Diagnostics.
There are four unique test buttons provided on the Ethernet Diagnostic Menu; however,
only the “RUN Loop-back out twisted pair” and “RUN Return hardware address” tests are
applicable to ControlWaveLP units.
