1.2  About the CalAmp Location Messaging Unit-4200™ (LMU-4200™) 
CalAmp's flagship LMU-4200™ product has the features, expandability, and flexibility with 
the intelligence to meet all customers’ ever changing needs in fleet management. The LMU-
4200™ offers a full set of features, comprehensive I/O system and expandable accessories 
that make it an industry leading value proposition. The LMU-4200™ expandability and 
flexibility lowers the cost of delivering, supporting, and growing fleet management solutions. 
The LMU-4200™ is designed to support customers needing an array of vehicle interfaces. 
For example, 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. In addition, the LMU-4200™ offers optional WiFi and Bluetooth 
capabilities. 
The LMU-4200™ also incorporates CalAmp's industry leading over-the-air device 
management and maintenance system software, , PULS™ (Programming, Updates, and 
Logistics System). Configuration parameters, PEG rules, and firmware can all be updated 
over the air. Our web-based maintenance server, PULS™ scripts, 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. 
1.2.1  Environmental Specifications 
The LMU-4200™ is designed to operate in environments typically encountered by fleet 
vehicles, including wide temperature extremes, voltage transients, and potential interference 
from other vehicle equipment. 
To ensure proper operation in such an environment, the LMU-4200™ was subjected to 
standard tests defined by the Society of Automotive Engineers (SAE). The specific tests 
included temperature, shock, vibration, and EMI/EMC. These tests were performed by 
independent labs and documented in a detailed test report. In accordance with Appendix A 
of SAE J1113 Part 1, the Unit is considered a “Functional Status Class B, Performance 
Region II” system that requires Threat Level 3 Testing. 
The following shows the environmental conditions the LMU is designed to operate in and 
the relevant SAE tests that were performed. No formal altitude tests were conducted.
