INTRODUCTION INTRODUCTION The EDACS® C3 Maestro™ dispatch console for Windows NT® is a state-of-the-art CRT-based dispatch console system designed to interface to an EDACS® CEC/IMC Digital Audio Switch. By leveraging the benefits of IBM® PC-compatible computer hardware and Microsoft’s Windows NT® operating system software, the C3 Maestro™ provides advanced console dispatch features for EDACS radio system networks.
AE/LZB 119 1892 R1A INTRODUCTION BASIC DISPATCH CAPABILITY • Basic dispatch functions provided by the C3 Maestro console for Windows NT are listed below. Most of these functions involve the console’s standard communication modules. Each standard communication module is programmable with a single entity for incoming call monitoring and outgoing console call transmission functions.
INTRODUCTION • • • • • • • Detailed Call History Indications—Three (3) separate operator-activatable dialog boxes provide detailed call history indications for the select entity/module (or entities/modules if selected entity changes are made), for the unselected entities/modules, and for all modules on a per module basis. Indications include the caller, the callee, call time, call type and the site number which the call is originating from.
AE/LZB 119 1892 R1A DESCRIPTION console, the console can be utilized to patch a telephone line to a talk group, a unit, a conventional channel or a talk-group patch in the CEC/IMC network. At the console, the CD may also be utilized like a standard telephone by the console user/dispatcher if radio patch operations are not transpiring.
DESCRIPTION (the "CRT"), a standard PC keyboard and a pointing device such as a mouse. A diagram illustrating equipment interconnections is shown in the Installation And Set-Up Manual included within this manual set. AE/LZB 119 1892 R1A NOTE NOTE For detailed PC hardware-related system specifications, refer to the C3 Maestro console for Windows NT Administrator’s Manual, AE/LZB 119 1897.
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.
DESCRIPTION NOTE NOTE SOFTWARE Microsoft Windows NT Workstation The C3 Maestro console for Windows NT product utilizes Microsoft’s Windows NT Workstation operating system software (version 3.51 or later). This operating system was chosen primarily for its built-in graphical user interface support, advanced networking ability including server/client operation and PC-AT computer platform operating capability.
AE/LZB 119 1892 R1A DESCRIPTION Enhanced Audio Enclosure, and mouse/track-ball generated headset sidetone volume change messages which must pass only to the Enhanced Audio Enclosure. The Dispatch Manager also receives many different type data messages from the Communications Interface.
DESCRIPTION using mouse/track-ball/touch-screen actions, or by the page up/down keys on the dispatch keyboard using keystroke actions. Up to eight (8) module pages, identified page A thru page H, can co-exist in each screen configuration. The maximum number of modules (all types) on a single module page is basically limited by the available screen display area. This area changes as monitor resolution changes are made and as other display items are added/deleted.
AE/LZB 119 1892 R1A DESCRIPTION monitoring at the console. Indications are displayed in one or more RSM modules. Each RSM module is assigned a status code number which corresponds to a unique radio unit-transmitted status code utilized throughout the EDACS radio system. 128 status codes are available for RSM and RTT operations.
DESCRIPTION hours:minutes:seconds digital-type format. Typically, this time is set and maintained at the CEC/IMC Manager. Time update messages are periodically sent from the CEC/IMC to all consoles connected to it via the respective CIM serial control data links. Therefore, all consoles’ clock indications are synchronized to the CEC’s/IMC’s time. Thus consistent time indications are displayed at all consoles interconnected to the CEC/IMC.
AE/LZB 119 1892 R1A DESCRIPTION Again, Figure 2 shows the factory-supplied screen configuration (with module page A chosen). The UDS Configurator-generated screen configuration shown in Figure 3 has significant differences from the factory-supplied screen configuration. First, as indicated by the number of buttons on the page button panel, it consists of only two (2) module pages—page A and page B.
DESCRIPTION Figure 4 snap-shot shows two (2) RSM modules on page B. This screen configuration is the same configuration utilized to take the Figure 3 snap-shot—only the chosen page differs; notice equal positioning of the static display items.
AE/LZB 119 1892 R1A DESCRIPTION The screen snap-shots shown in Figure 2 thru Figure 4 have one notable common aspect—they all utilize a screen resolution of 640 x 480 pixels. Higher resolutions allow more display items per module page. The snap-shot shown in Figure 5 illustrates this concept. It utilizes a screen resolution of 800 x 600 pixels. With this higher resolution, more screen area is available since each display item appears smaller on the screen at the higher resolution setting.
DESCRIPTION AE/LZB 119 1892 R1A DISPATCH KEYBOARD • five (5) telephone/intercom keys The C3 Maestro’s specially designed dispatch keyboard, shown in Figure 6, adds tactile-feel keyboard operation to the console thus providing dispatch speed capability equal to a modular-type console. It provides easy control for the advanced features of the C3 Maestro console.
AE/LZB 119 1892 R1A DESCRIPTION ENHANCED AUDIO ENCLOSURE The C3 Maestro console’s Enhanced Audio Enclosure contains all audio interface, audio routing and dispatch keyboard interface circuitry for the console system.
DESCRIPTION tions. Of the three (3) internal connectors, two directly mate with the Audio System Board. These two 96-pin rectangular DIN-type connectors carry all audio and control signals between the Audio System Board and the I/O Backplane Board's externally exposed connectors. The remaining internal connector provides the dc input connection from the power supply located under the Audio System Board.
AE/LZB 119 1892 R1A OPERATING PROCEDURES paging tone encoder is not required if the appropriate feature licensed software option is available at the console. The tone generation circuits are also utilized during automated test procedures performed at the factory. Firmware The operating program code for the microcontroller circuits within the Enhanced Audio Enclosure is stored on a factory-programmed 128K x 8-bit read-only memory (ROM) chip located on the Audio System Board.
