TESTING

After the NCM module has been configured and installed, it should be tested for proper operation before it is put into service. At present, the only test necessary to verify NCM performance is the loop test in NMS mode. This test is performed when the module is installed to verify operational performance in terminal, DI-A, or DI-B configurations.

TEST EQUIPMENT REQUIRED

1.PC with version 10.3 or greater of NMS.

2.IMUX 2000 Multiplexer.

3.Patch cord terminated in bantam jacks (2 required).

4.Male to female null modem RS-232 cable (RFL part number 303366-2 or equivalent)

LOOP TEST PROCEDURE FOR RFL NCM MODULES IN NMS MODE INSTALLED IN TERMINAL MULTIPLEXERS

The following procedure is used to test NCM modules installed in IMUX 2000 terminal multiplexers.

1.Connect the male to female null modem RS-232 cable from CH2 of the MA-401I to the DB9 male connector on the CM I/O.

2.Open the door on the front of the IMUX 2000 multiplexer.

3.Connect a patch cord between the EQUIP-T1-OUT and EQUIP-T1-IN jacks on the front of the IMUX 2000 chassis. The jacks are located on the Common Module.

4.With power applied to the IMUX 2000, check the indicators on the front of the power supply module.

The POWER indicator should be lit.

5.Check the Service LED (DS13) on the front panel of the NCM. See Figure 4 and Table 1 for location.

The Service LED should be illuminated green.

6.Check the ADRB LED (DS12) on the front panel of the NCM. See Figure 4 and Table 1 for location.

The ADRB LED should be illuminated solid orange. (should not be red or green) Orange indicates the NCM is receiving its own address.

7.Check the RXB LED (DS5) on the front panel of the NCM. See Figure 4 and Table 1 for location.

The RXB LED should be illuminated red.

8.Connect the PC to the CH1 RS-232 connector using the male to female RS-232 connector. At this point, the equipment should be connected as shown in Figure 9. Run the RFL NMS communications software and set the parameters exactly the same as the CM and the NCM.
