WIDE AREA MODULE (WAM)

Main Transmit

1.Determine the maximum level to be received by the ancillary equipment to be transmitted.

2.Set S5 for Test 1 (open section 1, close sections 2, 3 and 4).

3.Reset the module, Press S2 and release.

4.Adjust R44 for -12 dB from the maximum level in Step 1 at J12.

5.Select for normal operation (S5 all sections closed).

6.Reset the module, Press S2 and release.

Example: Microwave has -16 dBm max input, set J12 for -28 dBm.

Main Receive

1.Determine the maximum transmit level that is sent by the ancillary equipment to the interface module.

2.Select Test 1 (S5 open section 1, close sections 2, 3, 4).

3.Reset the module, Press S2 and release.

4.Insert an alignment tone -12 dB from the level deter- mined in Step 1 using a 600 ohm audio oscillator into EQU port of J1. Otherwise, set the ancillary equipment to send the alignment tone to the inter- face module.

5.Adjust R41 to be -6 dBm at J11, +6 dBm if maximum level is sent by the ancillary equipment.

6.Set S5 for normal operation (S5 all sections closed).

7.Reset the module, Press S2 and release.

Example: Microwave has +7 dBm maximum output. Apply -5 dBm and set J11 for -6 dBm or apply +7 dBm, then set for +6 dBm.

Secondary Transmit and Receive

Not used since the secondary line is not used.

19.4 WAM E&M-LEAD CONNECTIONS

NOTE: All WAM E&M Lead connection Examples and Figures reflect only one WAM configuration (WAC) and only one Switch per location.

Duplication of the following Examples and Figures are required for multiple, simultaneous WACs.

Multiple Switches per location that are included in a WAC in any of the following Examples and Figures need to daisy-chain E-Lead inputs and M- Lead outputs and then connect them together. (An example that has one Location with three Switches is shown in Figure 19-3.)
