Installing the TIM-SI

1. Locate the On Board Computer (OBC).

TIP – Typical mounting locations for the OBC are:

a. Behind or under the passenger seat

b. Behind or under the driver’s seat

c. For Sleeper Cabs, in the storage area under the

bed accessible from the outside of the truck, or in
the closet near the bed.

2. Select a Mounting Location for the

TIM-SI-SI.

TIP – Choose a location that will allow for easy routing
for the cable that runs between the TIM-SI-SI and the
OBC and between the TIM-SI-SI and the GPS Antenna.

IMPORTANT – The TIM-SI-SI wirelessly communicates
with the Airbat TPMS sensors; thus the mounting
location must meet the following requirements:

DO:

„

„

Mount the TIM-SI-SI at within 1” of window height
or higher
in the cab.

DO NOT:

„

„

Mount the TIM-SI-SI where metallic objects are
within 1” of the front face next to the upper right
hand corner of the box (where the receiving antenna
is located).

„

„

Mount the TIM-SI-SI within 12 inches of other
wireless transmitters (in-cab WiFi, Blu-tooth and
microwave ovens).

„

„

Mount the TIM-SI-SI outside the cab of the tractor,
the enclosure is not watertight.

Typically the TIM-SI-SI is mounted above the passenger
door (sleeper cabs) or on or near the lower passenger
side of the rear window (day cabs).

The TIM-SI-SI also may be mounted directly onto the
rear window. If this is the preferred mounting method, it
should be mounted on the passenger side in a position
that does not obstruct the drivers view.
