Product Overview
An advanced LTE Cat 1 telematics terminal combining GNSS positioning, CAN bus data access, remote tachograph downloads, and multi-interface connectivity for commercial fleet operations.
The GV355CEU supports LTE Cat 1 cellular connectivity with 2G fallback for reliable communication across supported EMEA networks. Over-the-air (OTA) management enables remote configuration, firmware updates, and device management. Built-in BLE 5.2 supports compatible wireless accessories.
The tracker provides access to vehicle data through CAN bus interfaces supporting J1939/FMS, light vehicle CAN, J1708, and tachograph-related connections. It supports remote tachograph data retrieval and DDD file downloads from compatible tachograph systems, helping fleets simplify data collection and compliance workflows. K-Line supports live tachograph data reading.
An integrated u-blox GNSS receiver provides vehicle positioning with autonomous accuracy of under 2 metres under suitable conditions. Location data supports real-time tracking, route history, and geofence monitoring for fleet visibility and operational oversight.
The GV355CEU supports driving behaviour monitoring, crash detection, tow alarms, scheduled reporting, and event-based alerts. These functions help fleet operators monitor vehicle activity, investigate incidents, and improve operational safety.
RS232, RS485, CAN, K-Line, 1-Wire, analog inputs, digital inputs, and digital outputs provide flexibility for vehicle integration. The 1-Wire interface supports compatible temperature sensors and iButton driver identification. BLE 5.2 enables connections to supported wireless accessories.
The device operates on an 8–32V DC power supply and includes a 250mAh Li-Polymer backup battery. Its compact 94 × 58.5 × 21 mm enclosure and integrated cellular and GNSS antennas support installation in compatible commercial and heavy-duty vehicles.
