3.11.4 Console Interface Connections – P2
This connector carries control signals and audio between the console and the voter chassis.
Most of the more important connections are also found on the 18 pin terminal block, TB13,
(Not found on some earlier hardware versions). See Table 3-5. The P2 and TB13 connections
are direct parallel connections, so only one or the other may be used for any particular signal
without consideration for double-terminations. P2 is a 15-pin Female D-sub connector, so the
mating connector must be D-15 male (included in the Accessory Kit).
In an expanded system, the P2 connector on the expansion shelf is cabled to the Expansion
Connector on the next chassis up the daisy chain. See Figure 2-4 and Figure 2-5 for cable
diagrams. Cables can be ordered from us, see Table 1-3.
Table 3-5 P2 - Console Interface Connections
PIN Signal Description
1 Voted Out A Balanced voted receive audio output to the console.
2 Ground Ground connection.
3 Console TX In B Balanced transmit audio input from the console.
4 N/C No Connection.
5 PTT/COR/Directed
COR Out Indicates if any site is keyed or when any SVM is unsquelched. (Internally
configurable- active high or low, or with delay).
Note: Transmitters should be connected to SVM TB1-TB12. See Table 3-2
6 Data Ground Dedicated ground connection for ext. clock and data.
7 Ext Clock In Serial clock input in an expanded system.
8 Ext Data Out Serial data output in an expanded system.
9 Voted Out B Balanced voted receive audio output to the console.
10 Console TX In A Balanced transmit audio input from the console.
11 Misc In EIA function tone select. (For SmarTrunk S/W only- Vote-lock enable instead)
12 Console PTT In PTT input from the console; active low.
13 Speaker Out Output to external monitor speaker.
14 Next Chassis Select In Chassis select input in an expanded system.
15 Ext Data In Serial data input in an expanded system.
Notes: For unbalanced audio, ground the “B” pin of audio pair connections; connect the single-ended
audio input to the “A” pin.
Active high and directed COR output features not available with older version CIM-2s. If there is no
jumper JP8 on the CIM-2 module, these features not available.
