Queclink GV350CEU — Next-Generation LTE Cat 1 Advanced Telematics Tracker with CAN, J1708 and J1939

The Queclink GV350CEU is a next-generation advanced telematics solution — a versatile LTE Cat 1 vehicle tracker built to cover every type of vehicle in a fleet from a single hardware platform. Where most CAN trackers support either light vehicles or commercial trucks, the GV350CEU covers both — reading advanced vehicle data from heavy trucks via CAN and J1708 interfaces and from light commercial vehicles and passenger cars via CAN bus, all without interfering with vehicle bus wiring or vehicle data ports.

Equipped with high-precision u-blox All-in-One GNSS, LTE Cat 1 with 2G fallback, BLE 5.2 for wireless accessory connectivity, an RS232 serial port, 1-Wire interface, multiple digital and analogue I/Os and a rich accessory ecosystem, the GV350CEU is purpose-built for telematics service providers and fleet operators who need a single, capable device across the full range of vehicle types — from company cars and light vans to HGVs, coaches and specialist machinery.

As an authorised Queclink distributor in the UK, Tracking Hardware UK ships the GV350CEU directly from our London warehouse — with trade pricing available for telematics service providers, fleet operators and resellers.

Key Features

• LTE Cat 1 with 2G fallback — reliable 4G connectivity for real-time fleet tracking across UK and international networks with automatic 2G fallback

• CAN bus interface — reads vehicle data from light commercial vehicles and passenger cars including fuel level, odometer, engine speed, engine temperature and more without interfering with vehicle bus wiring

• J1708 interface — reads advanced vehicle data from heavy trucks via the J1708 bus, the legacy heavy duty vehicle data protocol widely used in commercial transport

• J1939 support — supports the J1939 heavy duty vehicle CAN protocol for trucks, buses and specialist machinery

• Non-intrusive vehicle data reading — connects to vehicle data interfaces without interfering with bus wiring or vehicle data ports, maintaining vehicle warranty and simplifying installation

• RS232 serial port — connects to external accessories including fuel level sensors, Garmin navigation, RFID readers, tachographs and other serial devices via the 22-pin Molex connector

• 1-Wire interface — connects temperature sensors for cold chain monitoring and supports driver identification via iButton BLE 5.2 — connects to Bluetooth Low Energy sensors and accessories for extended monitoring including temperature, humidity, movement and cargo condition

• High-precision GNSS — u-blox All-in-One GNSS receiver supporting GPS, GLONASS, Galileo and BeiDou for accurate real-time positioning

• Multiple digital and analogue I/Os — 4 digital inputs including 1 positive trigger for ignition, 3 negative trigger inputs, 3 analogue inputs and 5 digital outputs plus 1 latched digital output for immobilisation and accessory control

• Remote immobiliser — digital output for remote vehicle disabling via your fleet management platform

• Crash detection — built-in accelerometer detects and records impact events for accident reporting

• Tow alarm — triggers an alert if the vehicle is moved without ignition

• Driving behaviour monitoring — tracks harsh braking, acceleration and cornering for driver behaviour scoring

• Geofencing — configurable zone alerts on vehicle entry or exit 250mAh Li-Polymer backup battery — maintains device operation if vehicle power is interrupted

• OTA control — remote firmware and configuration management

  
  

Driver Identification with Tracking Hardware UK BLE Keypad

The GV350CEU supports BLE 5.2 and is fully compatible with the Tracking Hardware UK BLE driver identification keypad. Drivers enter their unique PIN or present their card at the start of each trip, and the driver ID is logged alongside all CAN, GPS and telematics data — providing complete driver accountability across mixed heavy and light vehicle fleets. The 1-Wire interface also supports iButton driver identification for wired installations. Contact us to discuss keypad and GV350CEU bundle pricing.

Frequently Asked Questions

What vehicle types does the GV350CEU support?

The GV350CEU reads vehicle data from heavy trucks via CAN and J1708 interfaces, and from light commercial vehicles and passenger cars via CAN bus — all without interfering with vehicle bus wiring. This makes it one of the few trackers capable of covering heavy and light vehicle types within a single mixed fleet using the same hardware.

What is the difference between CAN bus, J1708 and J1939?

CAN bus is the standard vehicle data protocol used in most modern light vehicles. J1939 is the heavy duty vehicle CAN standard used in trucks, buses and agricultural machinery. J1708 is the older heavy duty serial protocol still widely used in commercial transport. The GV350CEU supports all three, ensuring broad compatibility across both modern and legacy heavy vehicle fleets.

What can be connected via the RS232 port?

The RS232 serial port connects to a wide range of external accessories including digital fuel level sensors, Garmin navigation devices, RFID readers, tachographs and other serial devices. This significantly extends the GV350CEU's capabilities beyond basic GPS tracking.

Is the GV350CEU compatible with the Tracking Hardware UK BLE driver identification keypad?

Yes — the GV350CEU supports BLE 5.2 and is fully compatible with the Tracking Hardware UK BLE driver identification keypad. The 1-Wire interface also supports iButton driver identification. Contact us for keypad and GV350CEU bundle pricing.
