1 Introduction
TheLN-Lisaself-containedvehicletrackingdevicethatcombinesGPSlocationwithLTECAT1/3G
fallbackcellular connectivity. It is primarily a location reporting device that responds to requests
(user, server) and events (timers, geo-fences). Data reports consist of a single record that
contains all location data and system status.
The device comes pre-configured from the factory. It is ready to use. TheLN-

• Input/outputs dedicated for ignition, relay, buzzer, and general purpose
• SerialUARTport
• Timers
• Watchdoglockupprotection
• Power management
• Event reporting
• Voltage monitoring
