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
