AUDIO TOWER REPLACEMENT

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 3-terminal 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.

AC POWER AND UPS EQUIPMENT

All consoles require 115 or 230 Vac (47 to 63 Hz) power sources. As a minimum, each outlet should be circuit- breaker protected per local building codes.

UPS protection is optional. Maximum required UPS wattage rating for a single console system should be based on the required maximum sums of the Enhanced Audio Enclosure (200 watts max.), the PC's computer (per manufacturer's specifications) and the PC's video display monitor (per manufacturer's specifications).

AUDIO TOWER REPLACEMENT

This section lists the steps necessary to replace earlier Audio Tower hardware with Enhanced Audio Enclosure hardware. Existing Personal Computer (PC) hardware is not replaced, only the C3 Maestro application software which it executes. To avoid duplication of information, many references are made to other Enhanced Audio Enclosure- related installation and set-up sections within this manual.

NOTE

NOTE

If installing a completely new C3 Maestro console system (new PC and new Enhanced Audio Enclosure equipment), disregard this section entirely and proceed to the "POWER-UP PROCEDURE" on page 25.

1.Power-Down and Cable Disconnections REMOVE AC POWER from the PC system.

REMOVE AC POWER from the Audio Tower G￿system.

Disconnect the Dispatch Keyboard from the Logic Board installed in the PC. If a new keyboard (with DB-9 connector) is supplied, this old keyboard is no longer needed.

G￿Disconnect the large PC-to-Audio Tower interconnect cable connecting the Audio Tower to the Logic Board installed in the PC. This cable is no longer needed.

At the Audio Tower, label and then disconnect all cabling between it and external equipment and accessories. Equipment and accessories includes items such as the Volume Controller Box, microphones, speakers, headset jack boxes, audio lines to and from the CEC/IMC, pager, recorder(s),

G￿Call Director, etc.

Remove the Audio Tower, Volume Controller Box, speakers and related cabling. These items are no longer needed.

2.LogicG￿Board Removal

Review the procedures in the documentation included with the PC relating to expansion board installation/removal.

Remove the PC's outside cover in accordance with G￿the manufacture's instructions.

Identify and remove the Logic Board installed in one of the PC's expansion slots. The large PC-to- Audio Tower interconnect cable (disconnected in step 1) mated with this board's DB-37 connector. The Dispatch Keyboard's small round DIN

G￿connector also mated to a connector on this board.

Using the screw which held the Logic Board in place, install a blank expansion slot cover (not supplied). Installation of this cover will prevent G￿dust and other foreign matter from entering the PC.

Replace the PC's outside cover.

3. G￿PC-To-Enhanced Audio Enclosure Serial Link

Using PC's CMOS set-up program, enable the PC's serial port (DB-9 connector) for COM2/address 2F8h and interrupt IRQ3 operation. If the PC is equipped with two serial ports, enable the second port (typically port "B"). The C3 Maestro's application software sets the port's baud rate. Refer

to the section entitled "SOFTWARE

INSTALLATION AND SET-UP PROCEDURE", subsection "PC CMOS SET-UPG￿PROGRAM" (page 26) for additional information.

Connect this serial port (COM2) to the Enhanced Audio Enclosure in accordance with subsection "PC-To-Enhanced Audio Enclosure Serial Data Interconnect Cable" in this manual (page 18).
