FINAL CHECK

Before the installation is complete, the Site Controller computer must be re-connected and the PMU option given a final operational check.

1.Re-connect the data link cable from the Site Controller computer to the right-hand VDT Interface connector on the back of the PMU (cable was temporarily disconnected for initial power-up and antenna mapping).

2.Verify that the “PWR” indicator on the front panel of the PMU stays on continuously.

3.Verify that the three other indicators on the front panel of the PMU are flashing in a repeating sequence. The “MUX” indicator should flash once every 250 milliseconds; first by itself, next with the “DATA” indicator, and then with the “ALARM” indicator.
