  • Page 15: Plan The Installation

    LMU may void the warranty. See the LMU Environmental Specifications for the exact measurements and specifications of the LMU-5541™. Typical installations will place the LMU under the vehicle dash board, or in the trunk. Make sure you can get access to the unit afterwards as under some circumstances it may be necessary to add additional wiring or connections to the LMU.

    You may find it useful to be able to view the LEDs periodically to make sure that the LMU is operating properly. If at any time you should encounter a problem with the LMU, you may need to read the LEDs in order to troubleshoot the problem. If you cannot fix the LMU yourself, you will need to provide the LED information to CalAmp customer support.

    9/28/23, 4:30 PM LMU-5541 Hardware & Installation Guide - PULS Wiki Be sure to consider the design decisions described in the previous sections. When you are ready to begin installing the LMU, follow these steps: 6.3.1 Place the LMU in the Vehicle Typically, the LMU should be placed under the passenger seat or dashboard of the vehicle.

  • Page 18: Installation Verification

    Note that these processes are all based on issuing AT Commands to the LMU-5541™. It is expected that installers will have access to a serial port expansion cable and a laptop or PDA capable of a terminal connection. Alternatively, an SMS message can be sent to an LMU-5541™ to obtain its current status.

  • Page 19: Inbound Verification

    6.4.3 Inbound Verification The last item to verify is that the LMU-5541™ is sending data to the correct server. In general, this is a two-step process that will need the aid of an observer on the back end. That is, a technician will have to be logged in so they can monitor data coming into the backend mapping/vehicle management application.
