Congratulations on your purchase of the ATrack AL7 Vehicle/ Motorcycle Telematics device. The AL7 is
equipped with state of the art Mobile and GPS technology, providing the most reliable up to date tracking
information of your vehicle’s current position or movement status. In addition to this, vehicle/ motorcycle
tracking can be combined with a variety of customized events based on your needs.

From the following diagram, the AL7 GPS receiver receives incoming signals from each orbiting satellite.
These signals consist of information such as satellite’s position and the time that the signal was transmitted by
each satellite. The receiver analyzes these data in order to determine how far away each satellite is and it
uses the triangulation method to calculate the vehicle’s exact position. Once the positioning data along with
other event data are gathered, they will be transmitted to the service center across a Mobile network (e.g.
GPRS/CDMA/UMTS) or via SMS. The communication is bidirectional, which means you can control the AL7
remotely across a Mobile network or via SMS.

The following table describes the function of each bare wire.
* The 1-Wire® Protocol supports up to three 1-Wire™ devices simultaneously, which means you can have
one (iButton® , DS1990A) and two 1-Wire™ temperature sensor probes (DS18B20)
** You may configure the AT$IOCG command to change these specific I/O pins to any of those functions
mentioned as above. Note: Please do not connect a positive voltage to any output pin!!!

Note: In the case of SIM PIN Error, the device will check the AT$SPIN every 10 minutes and try to
access the SIM again. The PIN will be validated 3 times and if it fails the last attempt, including the first
inserting time, the SIM card will be locked. Once the SIM is locked, you need to contact your GSM
carrier for the PUK in order to unlock the SIM card using your cell phone.

You may be able to explore great features on the AL7 through AT commands. The commands can be sent to a
device via USB, SMS or Mobile network (e.g. GPRS/CDMA/UMTS). The following diagram shows how to
configure a device with Hyper terminal via USB.
The following example shows how to connect the AL7 through HyperTerminal. You may use other popular
terminal emulators such as Putty or Tera Term Pro to establish a console session with the AL7.
(1) Run HyperTerminal and select the correct COM port and click on the [Configure…] button.

The GPRS or UMTS connection can either be enabled by typing the AT$GPRS command. Once enabled, the
ATrack ServerTool is then installed on a Windows PC in order to communicate with the AL7 remotely via a
GPRS or UMTS network. The ServerTool is a remote server application, which is mainly used for parsing data
by translating binary formats into readable formats or other testing purposes. Port forwarding is required if the
PC is located behind a Broadband router or any other firewall device or if it has third-party firewall software
installed. The communication is bidirectional, which means you can issue any AT command to the AL7 by
clicking the Send button. Please refer to the following snapshot and the Port forwarding website:
http://portforward.com/ for details.
