GV850CEU / GV850CNA
Queclink GV850CEU — Linux-based programmable telematics gateway with 4G LTE Cat 1. Official Queclink UK distributor.

Queclink GV850CEU — Linux-Based Programmable 4G Telematics Gateway with Dual CAN and Tachograph
The Queclink GV850CEU is the most advanced fleet telematics device Queclink has ever produced — a landmark product that redefines what a vehicle tracker can do. As the first high-end programmable product in Queclink's lineup, the GV850CEU is built on a high-performance Linux platform, giving fleet operators, telematics service providers and developers unprecedented control over device behaviour, data collection and integration — far beyond what any standard off-the-shelf tracker can achieve.
With dual high and low speed CAN bus ports supporting J1939 and FMS, a separate K-Line port for remote tachograph file downloading and live tachograph data, RS232 and RS485 interfaces, BLE connectivity, edge computing capability and support for data reporting at up to 60 times per second, the GV850CEU is purpose-built for the most demanding fleet management, logistics and industrial IoT applications where standard telematics devices simply cannot deliver the required level of data depth, customisation or performance.
As an authorised Queclink distributor in the UK, Tracking Hardware UK ships the GV850CEU directly from our London warehouse — with trade pricing available for telematics service providers, fleet operators, system integrators and resellers.
Key Features
Linux-based open platform — the first Linux-based programmable device in Queclink's lineup, supporting extensive customisation via multiple programming languages and a robust global developer community, enabling fleet operators to manage device programming independently
Edge computing capability — on-device data processing and logic execution enables intelligent event filtering, local decision-making and reduced data transmission costs without relying entirely on backend servers
Dual CAN bus ports — two independent high and low speed CAN bus interfaces supporting J1939 and FMS protocols for comprehensive data reading from HGVs, LGVs, passenger cars and heavy machinery simultaneously
Remote tachograph downloading and live data — separate K-Line port enables remote digital tachograph file downloading and reception of live driving status data including driver activity, driving time and rest periods for compliance monitoring
RS232 and RS485 interfaces — multiple serial interfaces for connecting fuel sensors, RFID readers, navigation devices, cameras and other third-party accessories via the 16-pin and 10-pin Molex connectors
4G LTE Cat 1 with 2G fallback — reliable future-proof connectivity for real-time fleet data transmission across UK and European networks with automatic 2G fallback
BLE connectivity — connects to Bluetooth Low Energy sensors and accessories for temperature, humidity, cargo monitoring and driver identification
Data reporting up to 60 times per second — exceptional reporting frequency for motorsport performance analysis, accident reconstruction and high-precision event recording far beyond standard telematics devices Hundreds of configurable geofences — supports configuration of hundreds or thousands of geofence zones based on specific routes and operational requirements — far exceeding the limits of standard trackers
CAN bus library for all vehicle types — built-in CAN bus library supports HGVs, LGVs, passenger cars and heavy machinery across diverse vehicle fleets
CAN synchronisation button — physical button for CAN bus synchronisation without requiring laptop connection
SIM and eSIM support — single SIM card slot with optional eSIM for flexible connectivity across deployments USB Type-C interface — for firmware updates, configuration and device debugging
Multiple LED indicators — dedicated GNSS, cellular, power and CAN status LEDs for clear installation and operational status confirmation
OTA control — remote firmware and configuration management
Driver Identification with Tracking Hardware UK BLE Keypad
The GV850CEU supports BLE connectivity and is 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, tachograph, GPS and telematics data. Contact us to discuss keypad and GV850CEU bundle pricing.
GV850CEU vs GV355CEU — Which Should You Choose?
Both devices offer tachograph downloading, CAN bus data reading and advanced fleet telematics. The GV355CEU is Queclink's most capable standard telematics device — delivering tachograph, CAN, J1708, RS232, RS485 and BLE in a proven, efficient platform for professional fleet operators. The GV850CEU is for operators who need to go further — with full Linux programmability, edge computing, dual CAN ports, data reporting at up to 60 times per second and the ability to build custom applications directly on the device. If standard fleet telematics is the requirement, the GV355CEU is the recommended choice. If advanced programmability, edge intelligence and maximum data depth are required, the GV850CEU is the correct platform.

Frequently Asked Questions
What makes the GV850CEU different from standard fleet trackers?
The GV850CEU is fundamentally different from standard fleet trackers — it is a fully programmable Linux-based telematics gateway. Fleet operators and developers can write custom applications directly on the device using multiple programming languages, configure hundreds of geofences, process data on the device via edge computing, and achieve data reporting rates of up to 60 times per second — capabilities that no standard tracker can provide.
Does the GV850CEU download tachograph files remotely?
Yes — the GV850CEU has a dedicated K-Line port for remote digital tachograph file downloading and reception of live tachograph data including driver activity, driving time and rest periods. This enables remote compliance monitoring without drivers needing to visit a download station.
What is edge computing on the GV850CEU?
Edge computing means the GV850CEU can process data and execute logic directly on the device itself — without sending all raw data to the backend server. This enables intelligent event filtering, local decision-making and significantly reduced data transmission costs, particularly valuable for high-frequency data applications.
Is the GV850CEU compatible with the Tracking Hardware UK BLE driver identification keypad?
Yes — the GV850CEU supports BLE connectivity and is compatible with the Tracking Hardware UK BLE driver identification keypad. Contact us for keypad and GV850CEU bundle pricing.
