TRK-240 In-Vehicle Mobile Message Display Terminal with GPS

What is a mobile data terminal (MDT)?

A mobile data terminal (MDT) is a portable device that is mounted in a vehicle to allow data communications between the vehicle and a central office. These devices are commonly used in industries where large fleets of cars or trucks need to be in contact with a dispatcher. Mobile data terminals have a variety of capabilities and features to assist the vehicle operator in accessing necessary information.

The mobile data terminal consists of a display screen with some control buttons mounted within easy reach of the driver and GPS tracking.

The primary use of the mobile data terminal is for communications between large fleets of vehicles and a dispatcher at a central location. The devices are used in a variety of fleets including taxis, police cars, buses, delivery service trucks, and emergency vehicles. They allow the dispatcher to send information to the driver, such as jobs, text messages of instructions or traffic information and directions, without requiring the use of a voice communications allowing the driver to refer to the message at any time.



TRK-240 Mobile Display Terminal (MDT) with GPS Tracking

The unit is compatible with a wide range of wireless infrastructures. In addition, a credit card reader, bar code scanner, external memory module, external keyboard or a mobile printer can be attached.

The terminal provides the driver with a 12 button keypad (with predefined message legends) describing the current activity of the user, e.g. on-site, in-service, out of service. When any of the status keys are activated the message is automatically displayed and transmitted to the base dispatcher using the existing wireless communications system. Audio and visual prompts assist the driver. When the status is received by the base and automatically acknowledged by the base dispatch software, the status key LED stops flashing and the current acknowledged status is displayed. If the status is not properly sent/acknowledged the Quadtec™ protocol continues to send the call automatically until the message gets through.

The system provides automatic number identification, auxiliary control inputs & outputs, status reporting with time stamping, selective calling, audio and visual indicators, GPS integration and many other important features to increase your operating efficiency and fleet control. All of this provides for lower operating expenses by providing the proper information quickly and easily.

The unit has a RS-232 port interface, together with digital inputs and outputs for automatic status registration.

The unit operates over most of the popular wireless networks including conventional and trunking radio, and cellular.

The base software system (
POWER-trak) provides a dispatcher with a menu driven Windows based (PC) software suite for tracking vehicle activity and message dispatch. This multi-channel software system provides a dispatcher with the required information in an easy to understand format. In addition to the main tracking screen, customer, vehicle, driver, history and plant views are provided. Comprehensive reporting, printing and setup capabilities are also supplied. The controller can be easily interlaced to any of the industry specific software systems which provide batching, management and accounting & CAD functions using the CES Wireless trak-CONTROL API.
