Software

The Personal Computer (PC) used with the C3 Maestro

console for Windows NT is delivered with its hard disk

drive formatted and Windows NT operating system software

installed. In most cases, MS-DOS is also installed and, in

this case, the PC is configured with dual-boot capability with

Windows NT being the default boot-up operating system.

MS-DOS is not required to run the C3 Maestro console for

Windows NT.

The C3 Maestro console application software is also

installed on the PC’s hard disk drive at the factory. The

console application software is also included with the

console equipment package on 3 ½-inch floppy disks in the

event software re-installation is required.

CAUTION

Always observe proper equipment handling

procedures to protect the equipment from ESD

damage. Refer to LBI-38737 for complete details.

BOARD SET-UP

ENHANCED AUDIO ENCLOSURE

Normally, the Enhanced Audio Enclosure is configured

at the factory for a standard C3 Maestro dispatch console

system installation. This configuration includes setting a

single 4-position DIP switch and programming all digital

pots for nominal audio input and output levels. The DIP

switch and digital pots within the Enhanced Audio

Enclosure are located on the Audio System Board.

NOTE

In most cases, changes to the factory DIP switch

and digital pot settings ARE

NOT

REQUIRED.

The following information lists the normal

factory settings and the optional settings which

are available. Digital pot setting changes must

be accomplished

after

most of the installation

procedures presented later in this manual are

complete and the console has been powered-up.

However, for completeness of this section, a

setting procedure is included on page 7.

Audio System Board

Mic Audio ALC Enable/Disable DIP Switch (S1)

DIP switch S1 on the Audio System Board is used to

independently enable or disable each microphone's

automatic level control (ALC) circuit. The switch has four

(4) positions, one for each mic that may be connected to the

Enhanced Audio Enclosure.

An Audio System Board ships from the factory with all

mic audio ALC circuits enabled. As shown in Figure 2, this

is accomplished by setting all four S1 switch positions to

"ON" or "CLOSED". Table 2 lists each switch position and

its corresponding microphone.

Normally, mic audio ALC should not be disabled.

However, if required, disable a mic's ALC by setting the

corresponding DIP switch position to "OFF" or

"OPEN". See manual AE/LZB 119 1892 for Enhanced

Audio Enclosure disassembly and Audio System Board

access instructions.
