How It Works

The TIM (Tractor Interface Module) is an intuitive device that that interfaces between the
PeopleNET on board computer and the BatRF wireless TPM sensors.

The TIM ships with the following:

1) A Tractor Interface Module

2) A PeopleNET g3 services interconnect cable

3) Adhesive backed mushroom Velcro and primer to mount the TIM

Installing the Unit

1) Locate the PeopleNET g3 Onboard
computer (OBC).

TIP – Typical mounting locations for the g3

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.

2) Select a mounting location for the
TIM. IMPORTANT – The TIM wirelessly

communicates with the Airbat TPMS
sensors; thus the mounting location must
meet the following requirements:

● DO mount the TIM at window height or
higher in the cab.

● DON’T mount the TIM 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).

● DON’T mount the TIM within 12 inches of
other wireless transmitters (in-cab WiFi,
Blu-tooth and microwave ovens).
Typically the TIM is mounted above the
passenger door (sleeper cabs) or on the
lower passenger side of the rear window.

TIP – Choose a location that will allow for
easy routing for the cable that runs
between the TIM and the PeopleNET g3
OBC.

4) Install the TIM

Peal the Mushroom head Velcro
adhesive back strip and adhere a piece
to each end of the back of the TIM.
Mount the mating pieces to the TIM
and remove the backing adhesive strip.
Press the TIM into its mounting
location so the adhesive will stick.
