Introduction
1.1 About the GSM/GPRS WorldTracker AVL
The GSM/GPRS WorldTracker AVL (hereafter referred to as "WorldTracker AVL") is an Automated
Vehicle Locating (AVL) device that utilizes a GSM/GPRS modem and a Global Positioning Satellite
(GPS) module. Working together, these technologies allow the WorldTracker AVL to simultaneously
act as a stand alone GPS reporting device and wireless data retrieval unit. The WorldTracker AVL
provides a flexible AVL solution with Input/Output
(I/O), six selectable National Maritime Electronics Association (NMEA) GPS data format, Trimble
ASCII Interface Protocol (TAIP) GPS data format, and Security Concepts's own proprietary Binary
GPS data format. The WorldTracker AVL is designed to work in a stand-alone device in an
automobile. Security Concepts's WorldTracker AVL provides maximum AVL versatility in a single
affordable device.

  • Page 6 2.2.2 WorldTracker AVL Serial Adapter (Optional) Security Concepts P/N can be used to provide a standard serial interface for the WorldTracker AVL. This adapter provides a standard DB9 serial interface and power to the unit. The adapter would be used for loading new software onto the WorldTracker AVL. The customer may choose to connect directly to the 12-pin connector serial interface pins, or order this convenient adapter from Security Concepts.
  • Page 7 Pins (8523-6) NOTE: Instead of using the previous two parts, you can build the cable using the Wago 733-112 connector. This connector is keyed, so the user won’t be able to insert the connector into the WorldTracker AVL the wrong way.
  • Page 8 There are three pins that are used to connect to the serial port of your computer. These are for transmit (out), receive (in) and ground. The following diagram displays the serial end of the interface cable. Pin 12 on the Pin 1 on the WorldTracker AVL WorldTracker AVL Pin 2 on the Worldtracker AVL...
  • Page 9 A SIM card can be installed by simply inserting the SIM card in the SIM slot provided in the front of the device. See Figure 10 - Inserting a SIM below. The SIM card is not provided with the WorldTracker AVL device. The SIM must be obtained from the GSM/GPRS service provider and must be provisioned by the operator for data and/or voice.
  • Page 10 The only way of connecting the microphone/speaker is via pins 3 - 6 of the 12-pin connector. Please follow the specifications as listed in the table below. Security Concepts is not liable for damage to the WorldTracker AVL due to user error. Ear – Speaker Output: Parameter...
  • Page 11 Ohms. The VSWR must be less than 2.0:1. System antenna gain should be 0 – 2 dB for optimum performance. The antenna connector on the GSM/GPRS WorldTracker AVL model is a TNC female connector. The antenna has to be connected to the connector labeled “MODEM ANT”. See Figure 11 - GSM/GPRS Antenna Connection.

    DC block installed in order to prevent shorting to ground. GPS antenna connector on the WorldTracker AVL model is a SMA female connector. The GPS antenna must be placed in an area where it can have direct view of the sky.
  • Page 13 2.7 Connecting the Power Source The GSM/GPRS WorldTracker AVL has an input voltage range of 9 – 30 V DC. (See Table 3 and Table 4). The power and ignition pins can support 9 – 30 V DC input voltage. The user has an option to connect these wires depending on the desired functionality.
  • Page 14: Led Operation

    Device in Low Power Mode when Ignition Turned Off Connect the power and ground wires of the WorldTracker AVL to the battery. Connect the ignition wire of the WorldTracker AVL to an auxiliary power source, i.e. ignition. Device enters low power mode when ignition line goes low. This feature has to be enabled via the software configuration (see AT$PWRSAV command for more details).
  • Page 15: Additional Software Features

    Additional Software Features The following software features are included in version 0.6.0 and greater: A user can send AT commands, via SMS, to the MTG in the following format: >RSP=[T/F];ID=[modem id];[at command]< ƒ [T/F] field has to be set to either T or F. Setting of T indicates that the response to an AT command will be sent back to the originator.
  • Page 16 The ability to store event data in memory, upon event trigger occurrence, and transmit data when desired. • The user can configure the WorldTracker AVL to store event-generated data, to be sent over the air to a remote server, in its internal memory. This feature can be enabled or disabled using the AT$MSGLOGEN command.
