MAINTENANCE

1.With the Operation Select Menu (main menu) shown on the screen, type 2 (for item #2 - Reports) and press the Enter key. The Report Selection Menu should then appear on the terminal as shown in Figure 23.

2.Type 5 (for item #5 - Channel Monitor) and press the Enter key.

3.At the “Monitor Unit ID (Y/N)?” prompt, press the Enter key (you do not need to type Y or N).

4.At the “Enter Channel Number (Enter to begin monitoring):” prompt, type a channel number from Table 9 (note that the zeros between AI or AP and the number may be omitted as shown), wait until the transmitter or antenna of interest is in use, and then quickly press the Enter key twice.

5.If the message “*** Channel Not Programmed ***”

appears on the line following your channel number entry, the transmitter or antenna selected was not in use. Repeat step 4 until the Channel Monitor screen is shown on the terminal.

The screen will automatically time out after 15 minutes and display the “press any key to continue monitoring” prompt. If you press any key within the 20 second grace period, the screen will continue for another 15 minutes. If you do nothing, the Report Selection Menu will appear at the end of the grace period. At any time you may press the Esc key to return to the Report Selection Menu.

SOFTWARE UPDATES

Don’t forget to redo any necessary programming (including antenna mapping). See the Programming heading in the Installation section.

If it becomes necessary to update the system software in the PMU, use the following procedure. This will undo all programming by the user (including antenna mapping during installation).

1.Switch the PMU’s On-Off switch to the off position.

2.Label and disconnect all cables and wires connected to the PMU.

3.Remove the PMU from the cabinet and remove the top cover.

4.Remove the board with the three PROMs labeled “F”, “E”, and “D” as shown in Figure 26.

PROM 1 "E"

PROM 0 "D"

5.Replace the three PROMs, being careful to orient them correctly in the correct socket.

6.Return the board with the three PROMs to the second connector from the front of the PMU, with the components facing the back of the PMU.

7.Make sure that the program data in the PMU is set to the factory default values by performing a Hardware Reset (see next heading). Start at step #4 and continue to the end.

ERASE ALL PROGRAMMING

CAUTION

Performing a Hardware Reset (power-up), with DIP switch #1 in the on position, will return the PMU’s parameters to the factory default values. This will erase all user programming (including antenna mapping during installation).

If the password has been changed from the factory default and you cannot remember it, you must erase all programming in order to regain programming access to the PMU. After erasing all programming, the password will be its default value of 8860. If you know the password and just
