LBI-39101 • GENERAL The intent of this manual is to guide field installation and maintenance personnel through the installation, set-up and testing of an EDACS® C3 Maestro dispatch console system equipped with an Enhanced Audio Enclosure. Figure 1 is a simplified diagram which indicates equipment interconnections in a typical installation.
PAGE 6
LBI-39101 PERSONAL COMPUTERS IMPORTANT NOTE In most cases, the Personal Computer (PC) used with the C3 Maestro console is delivered with its hard disk drive formatted and MS-DOS® operating system software installed on the hard disk drive. In addition, all C3 Maestro application software is also installed on the drive. Hardware Table 1 lists the PCs approved for use with a C3 Maestro console system equipped with an Enhanced Audio Enclosure.

LBI-39101 (on numeric keypad) keys. "Digital Pot Number: ?" is displayed in the lower left-hand side of the C3 Maestro's display. Digital Pots Settings To provide computer-controlled level settings, the Enhanced Audio Enclosure's audio input and audio output circuits incorporate 256-position digitally-controlled potentiometers. These digital pots, located on the Audio System Board, allow adjustment of the Enhanced Audio Enclosure's audio levels via the PC.

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.
PAGE 12
LBI-39101 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 Switch Customer-Specific System Documentation maintenance manual, LBI-38939 for sample print-outs and complete print-out explanations.

LBI-39101 ❏ If cable 19B804083P2 is used, mate its DB-25 to the Enhanced Audio Enclosure, route it to the CEC/IMC, shorten it as required, and punch the wires to the correct punch block's terminals. Wire color coding is indicated in Figure 5 and in the cable's assembly diagram shown at the end of this manual. Refer to the CEC/IMC customer-specific system documentation print-outs for CEC/IMC Audio Concentrator Card pin-outs which map over to the punch blocks via Telco cables.

LBI-39101 PERSONAL COMPUTER Dispatch Keyboard PC-To-Enhanced Audio Enclosure Serial Data Interconnect Cable The Dispatch Keyboard interfaces to the console system via the Enhanced Audio Enclosure. This keyboard's part number is P29/7590182003 (350A1371P17). It is sometimes referred to as the "custom keyboard". The PC-to-Enhanced Audio Enclosure RS-232 serial data link uses cable P29/5010150000 (350A1371P29).
PAGE 19
LBI-39101 NOTE NOTE Microphone priority is (highest to lowest): • Supervisory Headset Mic • Operator Headset Mic • Boom/Gooseneck Mic • Desk Mic Footswitches (if used) The boom/gooseneck mic has priority over the desk mic when no headset is connected. Desk mic audio will be ignored if a headset or boom/gooseneck mic is connected.
PAGE 20
LBI-39101 generally assembled with one amplified speaker in the far left-hand position (select speaker), one amplified speaker in the far right-hand position (unselect speaker) and blank panels installed in the two center positions. Four-speaker consoles are generally equipped with two separate 2-speaker rack mount assemblies. ❏ Install or mount each Speaker Assembly in a suitable location and then interconnect it to the Enhanced Audio Enclosure using cable P29/5010150000 (350A1371P29).

PAGE 23
LBI-39101 EQUIPMENT ROOM GROUNDING Proper grounding techniques should be observed in order to protect the equipment and service personnel from lightning and other sources of electrical surges. All consoles should be connected to properly grounded 3terminal outlets. If used, lightning arrestors, UPS equipment, and all other console-associated equipment should also be properly grounded. If necessary, refer to LBI-39067 for detailed grounding procedures.
PAGE 24
LBI-39101 ❏ 4. ❏ If necessary, obtain C3 Maestro application software V5.0 (or later). ❏ Install this software on PC's hard disk drive in accordance with the supplied instructions. ❏ Normally, no console-to-CIM serial link changes are necessary. However, if upgrading/replacing the plug-in RS-422 board installed in one of the PC's expansion slots (for improved static protection), the DB-25 connector which plugs to this board will, in most cases, require rewiring.
PAGE 25
LBI-39101 10. Speakers Speakers used with the Audio Tower are un-amplified units; therefore, they cannot be used with the Enhanced Audio Enclosure. Speakers used with the Enhanced Audio Enclosure are amplified units and each includes a volume control. The Volume Controller Box is not employed in Enhanced Audio Enclosure applications. ❏ Existing (old) speakers and the Volume Controller Box were disconnected in step 1.
PAGE 26
LBI-39101 6. Verify the LED on the Enhanced Audio Enclosure's front panel is illuminated. This signifies the power supply within the unit is operating. 7. Power-up the PC and monitor in accordance with the manufacture's instructions. 8. Continue with the software installation and set-up procedures that follow. SOFTWARE INSTALLATION AND SET-UP PROCEDURE NOTE Unless otherwise noted, all procedures in this manual should be performed in the order presented.
PAGE 27
LBI-39101 AUTOEXEC.BAT File Contents Serial Ports' Settings Contents of the AUTOEXEC.BAT file located in the root directory (C:\) are as follows. Changes are not recommended: Normally, the PC's COM1 serial port is utilized for CEC/IMC control data interfacing. The baud rate of this port may be set to operate at 19,200 or 9600. The 19,200 setting is recommended for all co-located console hook-ups.
PAGE 28
LBI-39101 ❏ If using CEC/IMC firmware version 2.x (and earlier), set the Call Director ID number from the Editor program's "CONFIGURATION DATA" form. Save changes to the hard disk drive. See LBI-39056 for complete details. ❏ If using CEC/IMC firmware version 3.x (and later) the Call Director ID setting should be made via the CEC/IMC Manager's "Console Hardware Configuration" option and then sent to the console. Digital Audio Switch Installation, Set-Up And Troubleshooting maintenance manual, LBI-38938.

LBI-39101 These databases can be downloaded by the console by requesting database uploads from the CEC/IMC Manager. Since this data is broadcast to all consoles in the CEC/IMC system, if possible, all consoles should be on-line when this upload occurs. This avoids having to repeat the process for other consoles at a later time. 1. From the CEC/IMC Manager's "CEC/IMC MOM Options" main menu, select the "System Manager Data" option. This will display the System Manager data menu. 2.
