Input and output cables
Relays
TTU peripherals (i.e. Serial adapter, jPOD, TetheredLocator)
Host serial devices (e.g. PDAs, laptops, other serial devices)
5.2 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
(TTU, antennas, peripherals, etc.). Be sure that the cables to the TTU are not bent or constricted in
any way. Also make sure that the TTU 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 TTU 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 TTU for the following
purposes:
Accurate data gathering and simulation of how customers actually use your solution
Ongoing monitoring and maintenance of TTU equipment
Accidental or intentional alteration of the equipment or cable connections
The following sections cover some of the issues to consider when planning your TTU installation.
5.2.1 Size and Placement of TTU Unit
The dimensions of the TTU should be taken into account, particularly when installing in a vehicle:
Whether you intend to place the TTU
under a seat or into a cavity behind the vehicle’s interior molded
trim, be sure the TTU will fit before drilling any holes or running cable
Be certain that the cables running to the TTU will not be bent or constricted. Damage to the cables
may impede the TTU
’s performance.
Be certain that the installation point will not violate any of the TTU
’s environmental specification
(temperature, moisture, etc…) as improper installation of the TTU may void the warranty.
