GPS seklys diMag DM13-4G

The diMag DM13-4G is a professional 4G LTE Cat 1 vehicle tracking terminal with fallback to 3G and 2G, multi-constellation GNSS, Bluetooth and a generous set of configurable inputs/outputs. It is hard-wired into the vehicle through a 2x6 (12-pin) socket and is built for serious fleet work: connect ignition sensing, an immobiliser relay, fuel-level (LLS) and temperature sensors, an iButton reader, a buzzer or status LEDs - and add a CAN adapter to read data straight from the vehicle bus on cars, trucks and special machinery.

With a built-in accelerometer (crash, towing and Green Driving scenarios), a 170 mAh internal backup battery and 128 MB of memory that buffers records out of coverage, the DM13-4G suits fleet management, car rental and leasing, taxi, public transport and logistics. It reports to the seklys.lt platform out of the box.

Why choose the DM13-4G

• Advanced, flexible I/O - 3 digital inputs, 3 digital outputs, 2 analog inputs, 1-Wire and a CAN-adapter input for rich vehicle integration (see the wiring scheme below)
• True 4G - LTE Cat 1 with automatic 3G and 2G fallback
• CAN data via adapter - read fuel, mileage and other bus data on compatible vehicles
• Driver behaviour & safety - accelerometer with crash detection, towing detection, Green Driving and over-speeding
• Bluetooth 4.0 LE - temperature/humidity sensors, OBDII dongle, iButton, barcode scanner and other BLE accessories
• 1-Wire - iButton authorisation and temperature sensors
• Internal backup battery - keeps reporting briefly after a power cut; 128 MB buffers data out of coverage
• Remote management - firmware and settings over the air (FOTA), plus USB / Bluetooth configuration
• Note: the DM13-4G is IP41 (basic dust/drip protection) - designed for protected in-vehicle installation, not for exposed or wet mounting

Find it by SMS

Need a quick location check without opening an app? Text the command ggps to the tracker's phone number and it replies with the current date, time, speed and a clickable Google Maps link to the vehicle's position.

Inputs / outputs and wiring

The 2x6 socket carries power plus the configurable I/O - connect ignition detection, an immobiliser relay, sensors, a buzzer, LEDs, a 1-Wire iButton/temperature sensor or a CAN adapter:

Installation

Insert the Micro-SIM and connect the battery, then wire the device to the vehicle:

1. Open the cover, insert the Micro-SIM (PIN request disabled) and connect the internal battery.
2. Wire the 2x6 socket: Pin 1 +10-30 V DC, Pin 7 ground; connect the digital/analog I/O, 1-Wire or CAN-adapter pins as your installation needs.
3. Mount the device in a protected spot away from heat and moisture; it is delivered pre-configured for seklys.lt, and settings can be changed over the air.
