BOARD SET-UP

PERSONAL COMPUTERS

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. Use of an unapproved computer will void the console system's warranty and support services. Subsequent to the printing of this manual, additional PCs not listed in the table may be approved.

Operating System Software

The PC will have MS-DOS version 6.x installed on its hard drive. Earlier versions of MS-DOSare not approved for use with the C3 Maestro console system equipped with an Enhanced Audio Enclosure.

NOTE

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

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.

IMPORTANT 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 correspondingG￿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 LBI-39100 for Enhanced Audio Enclosure disassembly and Audio System Board access instructions.
