LBI-39062 INTRODUCTION ® The EDACS C3 Maestro console system is a state-ofthe-art CRT-based dispatch console system designed to interface to an EDACS® CEC/IMC Digital Audio Switch. It provides enhanced console dispatch features on a PCAT™ computer platform.
LBI-39062 displayed page, the indicator is high-lighted in red. • System Status Area − This area indicates various status information such a console ID number, name or ID number of the caller, emergency status, and EDACS operational status (full-feature trunking, failsoft trunking, etc.). • Note Card Area − Note cards provide instructions and menus for module programming functions which are referred to as "module modify" operations.
LBI-39062 CEC/IMC Interface The PC's COM1 serial port provides the control data connection for the C3 Maestro. This serial data link between the Maestro and the Console Interface Module (CIM) within the CEC/IMC can be configured for RS-232 or RS-422 operation. Detailed configuration and wiring information is contained in the Installation, Set-Up and Testing maintenance manual (LBI-39055) included with this manual set. LOGIC BOARD The Logic Board is installed in one of the PC's internal expansion slots.
LBI-39062 • five (5) simulselect keys • eleven (11) patch keys • five (5) telephone/intercom keys • ten (10) function keys and an escape key AUDIO TOWER The Audio Tower contains all of the audio interface and audio routing circuitry for the C3 Maestro console system. This unit is interfaced to the PC by the Logic Board and the 37-conductor interconnect cable between the two units. furnishes 15 Vdc interconnections from the power supply to these boards.
LBI-39062 In a typical C3 Maestro console installation, the Audio Tower is equipped with only one Audio PA Board (#1) and this board is installed in the slot position adjacent to the Audio Matrix Board. In this installation, a blank cover plate is installed over the unused far right-hand slot position. However, a 3- or 4-speaker console or console connected to a Call Director requires a second Audio PA Board (#2) installed in the Audio Tower's far right-hand slot position.
LBI-39062 to-talk (PTT) button at one of the connected mics or a footswitch. A pager audio input is provided at the I/O Board. When enabled, paging audio overrides all other mic audio inputs. I/O Board The I/O Board used in the Audio Tower interconnects signals between the Audio Tower’s Backplane Board and the terminal blocks and connectors located on its front panel. In a typical C3 Maestro console installation, no or only a few devices are interconnected the I/O Board.
LBI-39062 The console uses a secondary LID (Logical ID) for the patch channel requests, thus allowing CD patch operation to work separately from, and concurrently with, the normal console-to-radio dispatch communications. This LID is referred to as the "Call Director ID". If the C3 Maestro console is connected to a Call Director, the Audio Tower must be equipped with two (2) Audio PA Boards. The second board interfaces the CD patch audio to CEC/IMC CIM channel four.
