INTERCONNECTING THE EQUIPMENT

LBI-39101

RS-422 BOARD

Most PCs used within the C3 Maestro console application are equipped with a plug-in RS-422 capable board for serial data interfacing to the CIM within the CEC/IMC Digital Audio Switch. Normally, no changes from the factory set-ups are required on this board or any other related serial COM port hardware within the PC. However, it may be beneficial to review the information in the section entitled "CEC/IMC INTERCONNECTIONS", subsection "Control Data Link" (page 12) at this time.

INTERCONNECTING THE

EQUIPMENT

A C3 Maestro dispatch console system equipped with an Enhanced Audio Enclosure requires the following interconnections. See Figure 1:

∙PC-to-CEC/IMC Data Concentrator Card control data link – Via twisted pairs, phone lines, punch blocks and/or 4-wire modem equipment. A 100-foot (30.5 meters) pre-wired cable is supplied for co-locatedRS-422hook-ups.

∙Enhanced Audio Enclosure-to-CEC/IMC Audio Concentrator Card audio link – Via 600-ohm twisted pairs, phone lines, punch blocks and/or mux equipment. A 100-foot (30.5 meters) pre-wired cable is supplied for co-located audio hook-ups.

∙PC-to-Enhanced Audio Enclosure control data link – A 9-foot (2.74 meters) pre-wired cable is supplied for this control data link.

∙Enhanced Audio Enclosure-to-Dispatch Keyboard

∙PC-to-Video Display Monitor

∙PC, Video Display Monitor and Enhanced Audio Enclosure AC Power Connections

In addition, the following connections are required if the related external devices are used with the console:

∙Enhanced Audio Enclosure-to-Desk Mic

∙Enhanced Audio Enclosure-to-Supervisor Headset Jack Box

∙Enhanced Audio Enclosure-to-Operator Headset Jack Box

∙Enhanced Audio Enclosure-to-Boom/Gooseneck Mic

∙Enhanced Audio Enclosure-to-Boom/Gooseneck PTT and Monitor Switches

∙Enhanced Audio Enclosure-to-Footswitches

∙Enhanced Audio Enclosure-to-Speaker Assemblies

∙PC-to-Standard PC Keyboard – The standard PC keyboard is only utilized during console start-up and maintenance operations.

In addition, the following interconnections are required for optional equipment, if employed:

∙Enhanced Audio Enclosure-to-Recorder Equipment

∙Enhanced Audio Enclosure-to-Pager

∙Enhanced Audio Enclosure-to-External Equipment Controlled by Relay Form-C Contacts

∙Enhanced Audio Enclosure-to-Call Director

NOTE

Unless otherwise noted, all procedures in this manual should be performed in the order presented.

CEC/IMC INTERCONNECTIONS

The C3 Maestro console interfaces to the CEC/IMC via a full-duplex serial control data link and a 4-wire audio connection for the select audio and microphone link. In addition, each unselect speaker at the console requires an additional 2-wire connection from the CEC/IMC. Also, if the console is interfaced to a Call Director for Call Director telephone patch operations, an additional 4-wire audio link between the C3 Maestro and the CEC/IMC is required. See Figures 1 and 6 and Table 5.

As shown in Figures 1 and 6, all CEC/IMC interconnections are made via Concentrator Cards. These cards are located at the back of the CEC/IMC cabinet. Control data connections are made via Data Concentrator Cards and audio connections are made via Audio Concentrator Cards. Typically, as shown in Figure 6, these connections are extended out of the CEC/IMC cabinet via Telco cables and terminations are actually made at punch blocks located external of the CEC/IMC cabinet.

CEC/IMC Concentrator Card pin-out details are listed on the customer-specific system documentation print-outs. These print-outs are included with the CEC/IMC when it ships from the factory. See the CEC/IMC Digital Audio
