LMU-4200 Series

Enterprise Location Messaging Unit with Heavy and Light Duty Vehicle Interface

CalAmp's flagship LMU-4230 supports a broad range of wireless connection options and comes equipped with either light or heavy duty vehicle interfaces. The LMU-4230's expandability and flexibility are key to lowering the cost of delivering, supporting, and growing fleet management solutions.



The LMU-4230 is designed to support enterprise customers needing a wide range of wireless connectivity, vehicle interfaces and peripheral interconnect. The LMU-4230 offers a full set of fleet features with cellular, WiFi, Bluetooth, and satellite connectivity options, plus a 3-axis accelerometer that detects and acts on hard braking, aggressive acceleration, or vehicle impacts. The LMU-4230 also features a comprehensive I/O system and expandable accessories that make it an industry leading value proposition. The serial ports supply switchable power at selectable voltages to ease the installation of peripheral data devices. The optional jPOD™ ECU (Engine Control Unit) interface reads and transmits heavy-duty engine condition and performance data such as engine temperature along with the fault codes to provide the best possible real-time picture of vehicle health.


The LMU-4230 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-4230 also leverages CalAmp's industry over-the-air device management and maintenance system, PULS™ (Programming, Updates, and Logistic 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.
