Version Reports (App Message 111)
Since the firmware versions strings are quite different between the LMU32 and EdgeCore
platforms, it is possible that the processing of LMDirect App Message 111 (Version Reports)
would require updating in order to properly parse the firmware version.
7.
Preparing for Installation
Be sure you have received all the LMU components you need. This must include:
•
The LMU to be installed
•
Optional Components:
•
Input and output cables
•
Relays
•
LMU peripherals (i.e. Serial adapter, jPOD, TetheredLocator)
•
Host serial devices (e.g. PDAs, laptops, other serial devices)
7.1 Plan the Installation
Verify Power, Ground and Ignition.
Be sure to check each source (power, ground and ignition) to ensure that
the proper signaling exists. This is typically accomplished with a multi-meter.
Before drilling any holes or running any wires, decide where each hardware component will be located (LMU,
antennas, peripherals, etc.). Be sure that the cables to the LMU are not bent or constricted in any way. Also
make sure that the LMU is kept free from direct exposure to the elements (sun, heat, rain, moisture etc...).
Be advised that an installation that violates the environmental specifications of the LMU will void the
warranty.
The best way to ensure a trouble-free installation is to consider your options and make some decisions before
you start. Take a look at the vehicle and determine how to best install the LMU for the following purposes:
•
Accurate data gathering and simulation of how customers actually use your solution
•
Ongoing monitoring and maintenance of LMU equipment
•
Accidental or intentional alteration of the equipment or cable connections
•
The following sections cover some of the issues to consider when planning your LMU installation.
7.2
Size and Placement of LMU unit
The dimensions of the LMU should be taken into account, particularly when installing in a vehicle:
Whether you intend to place the LMU under a seat or into a cavity behind the vehicle’s interior molded
trim, be sure the LMU will fit before drilling any holes or running cable
Be certain that the cables running to the LMU will not be bent or constricted. Damage to the cables may
impede the LMU’s performance.
Be certain that the installation point will not violate any of the LMU’s environmental specification
(temperature, moisture, etc…) as improper installation of the LMU may void the warranty.
