Table 3-23: Test Equipment Setup (GPS & LFR/HSO Verification)

Step Action

1 Perform one of the following as required by installed equipment:

- For local GPS (RF-GPS): Verify a CSM card with a GPS receiver is installed in the primary

CSM slot, CSM 1, and that the card is INS_ACT (bright green).

NOTE

Verify by checking the card ejectors for kit number SGLN1145 on the card in slot CSM 1.

- For Remote GPS (RGPS): Verify a CSM-II card is installed in primary slot CSM 1 and that the

card is INS_ACT (bright green).

NOTE

Verify by checking the card ejectors for kit number SGLN4132ED or subsequent.

2 Remove the card from slot CSM 2 (if installed) and connect a serial cable from the LMF COM 1 port

(via null modem card) to the MMI port on the card in slot CSM 1 (see Figure 3-9).

3 Reinstall the card removed from slot CSM 2.

4 Start an MMI communication session with the card in slot CSM 1 by using the Windows desktop

shortcut icon (see Table 3-15) .

5 When the terminal screen appears press the Enter key until the CSM> prompt appears.

CAUTION

In the power entry compartment, connect the GPS antenna to the

RF GPS connector ONLY. Damage to the GPS antenna and/or

receiver can result if the GPS antenna is inadvertently connected

to any other RF connector.
