Tractor Interface Module

PeopleNet Interface

STEMCO Part #821-7000

System Overview

The AirBAT Tractor Interface Module (TIM) is a state of the art wireless receiver designed to
keep drivers and maintenance personnel informed of tire issues in order to increase safety and
reduce costs. The TIM automatically receives and analyzes tire pressure data from AirBAT
sensors and issue alerts when a low tire condition is detected. The TIM notifies the driver via
the PeopleNet driver terminal and sends both SMS text and email alerts to the designated
recipients with date, time and location information. The TIM interfaces directly with the
PeopleNet g3 onboard computer system in order to pass information to the driver terminal and
to a PeopleNet network server. Data is then retrieved and acted upon by the BatRF WebBAT
application, which manages the alerts and aggregates the data for a given company ID.

Tractor Interface Module Features and Benefits

The TIM is designed to be easily installed and configured. Once the system is installed and set
up, you will begin to experience the benefits of real time tire pressure alert

Once you begin rolling down the road, you will begin to see the benefits of having real time tire
pressure alerts via the driver terminal, SMS text messages, and email.

WebBAT RF Information Manager

The WebBAT information management tool displays sensor data in actionable formats to
identify fleet conditions; problem vehicles; miles traveled; tire pressures; etc. Data can be
viewed as a web page, a .pdf file or a .cvs file format.

Sensors

AirBAT|RF® - Tire Pressure Monitor (TPM)

The AirBAT tire pressure monitoring sensor with visual LED display provides quick, on-tire
pressure identification. When mounted on the wheel end, the AirBAT continually monitors tire
pressures with visual alerts to indicate under-inflated tires.

TracBAT|RF – Electronic Hubodometer

Electronic mileage sensor with trip and life mileage feature: TracBAT’s mileage counting is

accurate within +/- 2%. TracBAT is often used to schedule maintenance by mileage activity
rather than time.

Installation

Installation instructions are provided in a separate document, the Tractor Interface Module
Installation Guide, which can be downloaded at www.batrf.com.

PeopleNet Driver Interfaces

PeopleNet offers a variety of driver interface options. However the majority of the terminals in the field
are the LCD type driver terminals. Due to the widespread use of these terminals, this is currently the
terminal that we will focus on for this manual.

Display Line 1

Normal Operation

The TIM provides useful information on the first (top) line of the driver terminal to support
driver pre-trip inspections and help drivers to monitor alert conditions. This information will
always be sent to line one on the display but will only be visible by the driver/maintenance
personnel when the terminal is on the home screen. If the display is not on the home screen,
you can get there by simply pressing the ▲(up arrow) several times. After this action, you
should be able to see BatRF TPM information on line 1 of the display.

Pressure & System Status

The left half of the first line on the display provides summary information. concerning the
pressure status and if any faults are present.

First Character – The first character is used to show whether or not the TIM is operational
and communicating with the PeopleNet on board computer. The first character slowly flashes
on and off. This character can be any one of the following:

“*” – The system status is good and there are no faults present. All of the bound

sensor tire pressures are above the low pressure limit and the vehicle is not in motion.

“Slow Twirling Bar” – Same as * except vehicle is in motion.
“!” - Indicates that there is a low pressure alert or a system error. Typical pressure

alerts will be either a low or flat tire alert and a system error can occur when no GPS
data is available.

Pressure Alert Line 1

! {Alert Type} Tire TPM## S^^

The generic message will be displayed first
followed by one or more tire specifics. The
{Alert Type} will either be "Low" or "Flat"
depending on which criteria are meet. If
more than one tire is below the limit and one
is at a low level and the other is at the flat
level then the word "Flat" will be displayed.

Tire Pressure Specific Message

!###PSI

If one or more of the sensors that are bound

report pressures equal to or below the low limit
then the display will alternate between a warning
message and the tire with the lowest pressure.

*OK BatRF – This message indicates that all bound tires are above the low limit pressure. If

the “OK” is shown in upper case it means that the communications with WebBAT (a remote
web service that sends the email/SMS alerts is working correctly). If shown in lower case it
means the remote connection to WebBAT was not successful. The TIM periodically transmits
messages to WebBAT. When power is applied to the TIM, the status will show a lower case
“ok” until the TIM has successfully received a response back from WebBAT (usually takes less
than 5 minutes). When there are no alerts or errors the information is sent to line 1 passively;
in passive mode the driver can chose to display other line 1 items such as the clock and the
BatRF TIM will not cause the display to return to the TPM display.

Bound Tires/Sensors

“TPM##” - Where ## is the total number of tires (not sensors) that are currently bound to the TIM.
“S^^” - Where ^^ is the total number of sensors that are currently bound.

In Cab Alerts

Pressure Alert Line 1

After a full screen alert has been issued the alert information continues to update on line 1 of
the screen. When an alert is present the TIM forces the information to appear on line 1 (no
longer passively).
