2.2 Basic Installation Instructions
Refer to manual sections 3, 4 and 5 for more complete instructions and explanations.
1) Unpack - Refer to Table 1-2 and the Installation Section of the manual.
2) Pilot Tone - For 2175 Hz pilot tone (rather than 1950 Hz), change switch SW2-1 from
"1" to "0" on each SVM module that uses 2175 Hz.
3) Transmitter Keying - If a relay contact closure to ground is needed, change JP4 of
SVM-2 #1 to pins 2&3 “E&M”. If EIA keying tones are used to key the transmitter,
change CIM module switch SW2-1,2,3 from "0,0,0" to "1,1,1".
4) Console Keying - If EIA keying tones will be sent from the console to the voter, change
CIM module switch SW2-6 from "0" to "1".
5) TX / RX Site Connections - The transmit site must be connected to SVM-2 #1, which
resides in the left most slot as viewed from the front of the voter. SVM-2 #1 interfaces its
transmitter and receiver via rear panel terminal block TB1:
Audio from receiver: use TB1 terminals 1(+) & 2
Audio to transmitter: use TB1 terminals 4(+) & 5
PTT output to transmitter: use TB1 terminal 18 (not needed with EIA keying output)
Ground to transmitter: use TB1 terminal 20
6) RX Site Connections - Connect the inputs to the SVM modules via the rear panel TB2
through TB12:
Audio from receiver site 2: use TB2 terminals 1(+) & 2
Audio from receiver site 3: use TB3 terminals 1(+) & 2
Audio from receiver site 12: use TB12 terminals 1(+) & 2
7) Console Connections - The console interfaces the SNV-12 CIM module via rear panel
TB13:
Console TX audio to voter: use TB13 terminals 1 & 2(+)
Voted audio to the console: use TB13 terminals 4 & 5(+)
PTT input to voter:
use TB13 terminal 7 (not needed with EIA keying input)
Ground to voter: use TB13 terminal 18
8) Connect Power - 110 VAC or 12 VDC. When power is applied, the unit will self-test.
The CPM-3 Fault LED will flash until the unit is fully ready to begin operation. The unit
may also be set for 220 VAC; see the Installation Section of the manual for details.
9) Adjust Audio Levels - RX audio at each SVM must be adjusted as detailed in Section
3.12.6.6. TX audio must be set for proper transmitter operation. If a console is used, its
audio to the voter‟s CIM console TX audio input must also be adjusted as detailed.
