2.10 DISPATCH POSITION CONNECTIONS

Each dispatch position will plug directly into the J1 connector on the PIC line terminator board as shown in Figure 2-15.Console positions having more than four speakers will have two or more PICs and line terminator boards assigned. A label on the top of the line terminator board, as shown in Figure 2-15,will identify the position with the Console ID. The jumpers on the line terminator board determine whether the selected audio is sent to the left or right speaker on the console. Refer to the VR-CM50 Con- sole Service Manual to adjust them. Refer to Section

2.6for grounding information.

2.11VOTER SYSTEM CONNECTIONS

If this system is specified for use with a voter system, the CPP is equipped with a TDM-AUX/V card for each voter shelf to be connected. The connec- tion to each voter is through a 25 pair, male ribbon connector and a local interface board to be installed at the voter shelf. The I/O CONNECTOR PANEL ASSIGNMENTS report will define the connector position for each voter. The VOTING COMPARA- TOR DISPLAY/CONTROL MODULE report, as shown in Figure 2-9, defines the site and control con- nections. This report is formatted for either General Electric or Motorola voters in accordance with the data furnished to E.F. Johnson at the time of order. These reports are interleaved with the RTL I/O PAIR ASSIGNMENTS sheets at the designated connector locations. Refer to the VR-CM50 Voter Modification Kit Installation Guide - P/N 700901 ECL A, for spe- cific voter shelf connection details.

2.12 LOGGING RECORDER CONNECTIONS

Mixed Tx/Rx audio for each individual channel is provided for connection to a logging recorder. The logging recorder output is a 600W balanced line at a level of -10 dBm. On tone controlled channels, the transmit audio will be stripped of guard tone (2175 hz) and function tones. On DC controlled channels, the transmit audio is DC blocked.

In the case of multi-receiver base stations, the audio from all receivers is summed with the transmit audio by bridging the logging recorder outputs of the LIC and the QRC cards. Jumpers on the QRC card, associated with the base station, can be set to isolate individual receiver audio, if required.
