AE/LZB 119 1892 R1A DESCRIPTION

monitor may be optionally substituted with a touch-screen

monitor.

Touch-Screen Monitor (Optional)

A touch-screen monitor allows the user to control the

console/computer by directly touching the monitor’s screen

surface with a finger or any small pointer-like object.

Basically, a touch is equivalent to a mouse point-and-click

action in the same approximate area of the screen. The

C3 Maestro console for Windows NT graphical user

interface was designed for 100% touch-screen dispatch

operability without the need of any other user input device

such as a mouse or the dispatch keyboard. In addition, since

mouse and dispatch keyboard operation is not disabled when

a touch-screen monitor is added to a console, the addition of

the touch-screen monitor adds user input redundancy to the

console. In summary, the addition of a touch-screen monitor

greatly enhances the console’s operational value. As of the

writing of this manual, both 14- and 17-inch monitors are

available from the factory.

Touch-screen monitors utilized with the C3 Maestro

console employ a nearly invisible sensor matrix embedded

on the monitor’s screen surface. Touch-screen monitor-to-

PC interfacing electronics consist of either a standard

RS-232 serial link from the monitor to one of the PC’s COM

ports or, as previously mentioned, a special controller board

installed in one of the PC’s expansion slots. An interface

cable between the monitor and the PC carries touch data

from the monitor to the PC. As of the writing of this manual,

touch-screen monitors are factory-supplied and configured

for COM port serial interfacing; therefore, no special touch-

screen controller board is required.

Standard PC Keyboard

A standard 101/102-key PC-compatible keyboard is

supplied with the console equipment package. During

normal dispatch operations, this keyboard is not used.

However, during the console set-up process, access to this

keyboard is required for custom configuration of both

Windows NT and the console application, and for basic file

management tasks.

Pointing Device (Mouse/Track-Ball)

Normally, the pointing device supplied from the factory

with the console is a standard 2-button PS/2-compatible bus

mouse. Optionally, other pointing devices may be utilized

such as a track-ball.

A pointing device is utilized to speed and ease user

input operations to the console application’s graphical user

interface. It is also beneficial for similar operations within

other Windows NT applications such as Program Manager,

File Manager and the console’s Configuration Editor

program.

CEC/IMC Serial Link

Normally, a C3 Maestro console equipped with an

Enhanced Audio Enclosure uses the plug-in RS-422-capable

board’s serial port configured as COM3 for control data

interfacing to the Console Interface Module (CIM) within

the CEC/IMC. This serial data link can be wired for RS-232

(3-wire) or RS-422 (4-wire) operation. Typically, a

C3 Maestro is co-located with the CEC/IMC and wired to

the CEC/IMC via RS-422 interconnections operating at a

19,200 baud rate. In a co-located installation,

console ⇔ CIM serial control data links up to 4000 feet

(1219 meters) in length may be employed if RS-422

interfacing is utilized.

If the console is not co-located with the CEC/IMC, full-

duplex 4-wire data modems and dedicated 4-wire data grade

phone lines (or equivalent) may be employed between the

CEC/IMC and the remote C3 Maestro console. In an

installation of this type, both the local serial link at the

console (COM3 port ⇔ console's modem) and the local

serial link at the CEC/IMC (CIM ⇔ CIM's modem) are

typically wired via RS-232 hook-ups. Normally, these

RS-232 links are configured for 9600 baud operation.

Detailed console ⇔ CEC/IMC wiring and configuration

information is contained within the Installation And Set-Up

Manual included within this manual set.

Enhanced Audio Enclosure Serial Link

In most cases, the PC's COM1 serial port is utilized for

control data communications between the PC and the

Enhanced Audio Enclosure. This serial port is wired for

RS-232 operation at 9600 baud. Control data transferred

over this duplex serial link includes Enhanced Audio

Enclosure-to-PC messages such as dispatch keyboard

keystrokes and VU meter data, and PC-to-Enhanced Audio

Enclosure messages such as start-up initialization

commands, recorder audio switching commands, and Call

Director audio switching commands.

See the Installation And Set-Up Manual included within

this manual set for wiring and configuration information.

Touch-Screen Serial Link (Optional)

As previously stated, if the C3 Maestro console is

equipped with a touch-screen monitor the console is

normally factory-supplied and configured for PC COM port

touch data serial interfacing (vs. PC expansion bus

interfacing via a specialized touch-screen controller board).

In this case, touch data is typically interfaced via the COM2

serial port operating at RS-232 levels. No specialized touch-

screen controller board is required when standard COM port

interfacing is employed for the touch-screen monitor’s

interface.
