FOX5 Series
4G LTE Cat 1 bis edge gateway for critical asset monitoring and vehicle telematics, with GNSS dead reckoning.
- LTE Cat 1 bis
- Modbus, CAN, J1939
- GNSS dead reckoning
- BLE 5.4

Overview
FOX5 is a cellular edge device that collects data from generators, HVAC plant, fuel tanks, compressors and vehicles and sends it to the cloud over 4G LTE Cat 1 bis. It connects to assets through RS-485, RS-232, CAN bus, 1-Wire and BLE 5.4, and reads vehicle data via OBD-II and J1939. Logic written in Lua or PFAL runs on the device to filter and process data locally, which reduces cellular and cloud costs. Fleets are provisioned and managed through Lantronix Percepxion.
Built for
- Telecom tower generator and battery monitoring
- Commercial vehicle and cold chain telematics
- Rental equipment location and utilisation
- Facility HVAC, boiler and fuel tank monitoring
