INSTALLATION

19.At the “Enter New Data:” prompt, type up to 4 characters for the password and press the Enter key. Check the password shown on the Site Data #1 screen to be absolutely sure it is what you expected and want. If not, return to step #8 and redo the password. If you try to enter more than 4 characters, only the first 4 will be used. After you are satisfied with the password, go on to the next step.

20.Type E (to end programming this screen) and press the Enter key. The Setup Selection Menu should then appear on the terminal.

Antenna Mapping

Antenna Mapping tells the PMU which antenna is used by each transmitter. The factory defaults have AI025 (antenna #1) mapped for transmitters #1 through #10 and AI027 (antenna #2) mapped for transmitters #11 through #20. If any transmitter is connected to an antenna other than described by these default values, the Antenna Channel parameter must be re-configured.

The following steps must be repeated for each transmitter that is connected to a different antenna # than described by the PMU’s factory defaults. Those transmitters for which the PMU’s factory defaults are correct, may be skipped. Transmitters may be configured in any order, but starting with the lowest transmitter # and working your way up will probably be the easiest way to keep track of which ones have been done.

21.With the Setup Selection Menu shown on the terminal, type 4 (for item #4 - Analog Input Channel) and press the Enter key.

22.At the “Enter Channel Number” prompt, type the channel number of the transmitter and press the Enter key. The Analog Input Channel screen for that channel should then appear on the terminal (see Figure 18). (If item #10 - Channel Enable Method = 5, item #11 will not be present.)

23.With the Analog Input Channel screen shown on the terminal, type 1 (for item #1 - Channel Type) and press the Enter key.

24.At the “Enter New Data” prompt, type 3 and press the Enter key. The screen will be re-written to add item #11 (or #12) - Antenna Channel (see Figure 19).

25.Type 11 or 12 (whichever corresponds to the Antenna Channel) and press the Enter key.

26.At the “Enter New Data” prompt, type AI025 for antenna #1 or AI027 for antenna #2, and press the Enter key. The screen will be re-written to show the new value.

27.Type E (to End programming this channel) and press the Enter key. The Setup Selection Menu should then appear on the terminal.

This completes the configuration of the Antenna Channel parameter for the selected transmitter. If this parameter needs to be changed for another transmitter, return to step 21. When this parameter is satisfactory for all transmitters, go on to step 28.
