referring toFigure 3-12 as required.
Table 3-19: Test Equipment Setup (GPS & HSO Verification)
Step Action
1 Perform one of the following operations:
– For local GPS (RF–GPS), verify a CSM board with a GPS receiver is installed in primary CSM
slot 1 and that CSM–1 is INS.
This is verified by checking the board ejectors for kit number SGLN1145 on the board in slot 1.
– For Remote GPS (RGPS), verify a CSM2 board is installed in primary slot 1 and that CSM–1 is
INS.
This is verified by checking the board ejectors for kit number SGLN4132ED (or later).
2 Remove CSM–2 (if installed) and connect a serial cable from the LMF COM 1 port (via null modem
board) to the MMI port on CSM–1.
3 Reinstall CSM–2.
4 Start an MMI communication session with CSM–1 by using the Windows desktop shortcut icon (see
Table 3-3)
NOTE
The LMF program must not be running when a Hyperterminal session is started if COM1 is being
used for the MMI session.
5 When the terminal screen appears, press the <Enter> key until the CSM> prompt appears.
