Dual CPU
The M1 MDT features a dual-processor architecture that separates computing and automotive control tasks to ensure stability, performance, and energy efficiency.
Main CPU
Samsung ARM 400 MHz processor
Optimized ARM architecture for efficient performance and low power consumption
Secondary CPU (AITP – Automotive Intensive Task Processor)
Manages power control and safe shutdown
Handles wheel pulse, speed, and distance calculation
Supports Wake-Up on Ring for remote activation
Provides Over-the-Air (OTA) software and firmware updates
Always active, it can switch the device and peripherals on or off automatically
This intelligent dual setup guarantees reliable operation, remote management, and optimized power control — ideal for continuous fleet operation.
Ideal for fleet management and job distribution
The M1 MDT is an all-in-one terminal that represents the state of the art in fleet management, combining power, compact design, and full connectivity for dispatching and control.
Key features:
GPRS modem for stable, real-time communication with the operations center
U-Blox 6 GPS receiver (50 channels) with GALILEO compatibility for precise vehicle positioning
Independent module management — GPS and GPRS can operate separately from the Windows CE system
Hardware MUX port for sending AT commands during active connections, enabling signal and status diagnostics
AITP processor autonomously manages communications and power supply, maintaining GPS and data transmission even when the main system is off
- Integration with the Digitax Device Track platform for full fleet supervision
This configuration ensures uninterrupted fleet monitoring, efficient data exchange, and reliable connectivity under all operating conditions.
Digitax SDK for APP and solution integration
The M1 MDT includes a ready-to-use Digitax SDK, designed to simplify the integration of advanced automotive systems and third-party applications.
Key benefits:
Seamless connection with CAN Bus, I/O controls, and external modules
Fast development of custom fleet and dispatching applications
Full technical support from Digitax during integration and testing
With its open architecture, the SDK allows developers and system integrators to create tailored solutions that ensure compatibility, scalability, and reliable performance across Digitax platforms.
Customizable User Interface
The M1 MDT features a 4.3-inch 16:9 TFT display (480×272), providing a bright, responsive interface for professional fleet applications.
The integrated touchscreen controller and nine LED-backlit hardware buttons enable fast and reliable interaction, while preventing touchscreen wear during intensive use.
The ambient light sensor automatically adjusts display brightness for optimal visibility in any lighting condition — day or night.
A programmable smart power button adds flexibility and control, allowing operators to:
Press briefly to boot from the system disk
Long press to boot from the microSD card
Long press (safe mode) to shut down Windows CE safely
It can also be disabled or configured to activate Ghost Mode, keeping the system active while appearing off — ideal for discreet operations or energy saving.
Dual boot function
The Dual Boot Function allows the M1 MDT to restore or update the entire system at any time — from user applications to the operating system and CPU firmware.
The device can boot from two independent drives:
Flash Disk — used for applications and operational data
microSD card — dedicated to large file storage (maps, images, videos, logs) and system recovery or initialization
This flexible architecture ensures safe updates, quick maintenance, and reliable performance even in demanding fleet operations.
Stealth Mode
Stealth Mode allows the M1 MDT to remain fully operational while the display is turned off, ideal for discreet monitoring or energy-saving operation.
Main functions:
Remote vehicle control: The control center can remotely activate the device, even with the screen off, to check GPS position, record ambient audio, or retrieve operational data.
Ghost Mode: When the power button is pressed, the device can enter Stealth Mode instead of shutting down, maintaining data transmission with minimal power consumption.
Alarm management: In case of an alarm, the system can start in Stealth Mode, automatically sending alerts, GPS location, screenshots, or audio to the control center — without drawing attention.
This feature ensures continuous communication, remote security control, and discreet operations in all fleet environments.
Connectivity
The M1 MDT provides a wide range of communication channels to ensure seamless integration with vehicle systems and external equipment.
Main interfaces:
2 high-speed USB 2.0 Hosts and 1 USB OTG port for data transfer and peripheral connection
Up to 4 RS232 serial ports for direct communication with on-board devices
Programmable digital inputs and outputs for controlling external components and reading signals from sensors or auxiliary systems
This flexible interface architecture enables easy integration, data synchronization, and real-time connectivity across the entire fleet.
Easy to Install
M1 MDT is a product designed to be installed above the rearview mirror, ensuring installation without compromising the aesthetics of the car. Extremely durable and robust, it is designed to be extremely reliable in all professional applications.
Certified for Professional Use
M1 MDT is fully certified for the R10 regulation and the R21 OIML regulation, as well as the European MID certification for use as a Taximeter and MDT in the same device.
