The optional jPOD™ ECU (Engine Control Unit) interface reads and transmits heavy-duty engine conditions and data such as engine temperature along with fault codes providing a real-time picture of vehicle health. In addition to cellular based communications, the LMU-4520 offers optional Satellite or WiFi technologies. This expandable architecture saves upfront costs while allowing your solutions to grow with customers’ changing needs.


The LMU-4520 employs CalAmp’s industry leading on-board alert engine, PEG™ (Programmable Event Generator). This advanced engine monitors external conditions and supports customer-defined, exception-based rules to help meet the needs of your application. PEG continuously monitors the vehicle environment and responds instantaneously to pre-defined threshold conditions related to time, date, motion, location, geo-zone, input and other event combinations. With PEG, your unique application will meet demanding customer requirements. This behavior can be programmed by CalAmp before shipment, at a customer’s facility, or over-the-air once the unit has been fielded.


The LMU-4520 also leverages CalAmp's industry leading over-the-air device management and maintenance system, PULS™ (Programming, Updates, and Logistics System). Configuration parameters, PEG rules, and firmware can all be updated over-the-air. PULS offers out-of-the box, hands-free configuration and automatic post-installation upgrades. You can also monitor unit health status across your customers' fleets to quickly identify issues before they become expensive problems.
