5 Installing the LMU
5.1 Preventing Accidental or Unauthorized Modification
If you anticipate that fleet drivers or others might interfere with the LMUs once they are installed, take
steps to be sure that it is not easy to remove the LMU from its power source, etc. Two common
methods are the use of Tamper Proof Sealant or creation of PEG Script to detect power loss or GPS
antenna disconnections.
5.2 Installing the LMU in a vehicle
1. Make sure the vehicle is turned on/running when plugging in the unit. If the unit is plugged in while
the vehicle is off it will need to complete the detection process on the next ignition on cycle in order to
operate correctly.
2. Plug the unit into the OBD2 connector of the vehicle while it is running, and do NOT turn off the
ignition.
3. Leave the unit plugged in with vehicle ignition on until the detection process has completed. Vehicle
detection status can be checked through SMS over the air or with AT Commands using the CalAmp
serial connection cable.
