GPS seklys DM15-4G su CAN

The DM15-4G is a professional 4G LTE Cat 1 vehicle tracker with a built-in CAN data processor - a compact "2 in 1" unit that combines a GNSS/LTE tracker and a CAN adapter in one housing. It reads live vehicle data straight from the CAN bus of light vehicles, electric vehicles, trucks and buses: fuel level and total fuel consumption, engine RPM, wheel-based speed, driven distance and accelerator pedal position - no external CAN adapter needed.

Hard-wired through a 2x6 (12-pin) socket, it offers configurable digital/analog inputs and outputs, 1-Wire (iButton / temperature sensors), Bluetooth LE for wireless sensors, a 170 mAh backup battery and 128 MB of memory that buffers records out of coverage. The DM15-4G is the natural choice for fleet management, logistics, delivery services, utility transport, car sharing and rental fleets that need real vehicle data - not just a position on a map. It reports to the seklys.lt platform out of the box.

Why choose the DM15-4G

• CAN data without an extra adapter - the CAN processor is inside; two CAN interfaces read the vehicle bus directly
• Real fuel data - fuel level and total consumption from the vehicle, plus the GNSS Fuel Counter scenario
• EV ready - CAN data reading from a wide range of electric vehicles, alongside light vehicles, trucks and buses
• True 4G - LTE Cat 1 with automatic 2G (GSM/GPRS) fallback
• Driver behaviour & safety - accelerometer with crash detection, towing detection, Green Driving, over-speeding and excessive-idling scenarios
• Bluetooth 4.0 LE - temperature/humidity sensors, barcode scanner and other BLE accessories
• 1-Wire - iButton driver authorisation and temperature sensors
• Internal backup battery - keeps reporting briefly after a power cut or unplugging; 128 MB buffers data out of coverage
• Remote management - firmware and settings over the air (FOTA), plus USB / Bluetooth configuration
• Note: the DM15-4G 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, the two CAN lines and the configurable I/O - connect the vehicle CAN bus, ignition detection, an immobiliser relay, a fuel gauge or LLS sensor, an alarm button, a buzzer, LEDs, or a 1-Wire iButton / temperature sensor:

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 CAN1 (pins 6/12) and, if needed, CAN2 (pins 5/11) to the vehicle bus, plus the digital/analog I/O or 1-Wire pins 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.
