1. Introduction
The AVL300 is a powerful GPS locator designed for vehicle or asset tracking. It has
superior receiver sensitivity, fast TTFF (Time to First Fix) and supports Quad-Band GSM
frequencies 850/900/1800/1900, its location can be monitored in real time or be
periodically tracked by a backend server or other specified terminals. The AVL300 has
multiple input/output interfaces that can be used for monitoring or controlling external
devices. Based on the integrated @Track protocol, the AVL300 can communicate with a
backend server through the GPRS/GSM network to transfer reports of Emergency,
geo-fence boundary crossings, low backup battery or scheduled GPS position as well as
many other useful functions. Users can also use AVL300 to monitor the status of a vehicle
and control the vehicle by its external relay output. System Integrators can easily setup
their tracking systems based on the full-featured @Track protocol.
This device complies with part 15B, part 22 and part 24 of the FCC rules. Operation
is subject to the following two conditions: (1) this device may not cause harmful
interference (2) this device must accept any interference, including interference
that may cause undesired operation.

PWR (PI 12) / G D (PI 6) are the power input pins. The input voltage range for this
device is from 8V to 32V. The device is designed to be installed in vehicles that operate on
12V or 24V systems without the need for external transformers.

3.8. Ignition Detection
Table 7: Electrical Characteristics of Ignition Detection
Logical State Electrical State
Active 5.0V to 32V
Inactive 0V to 3V or Open
Figure 10. Typical Ignition Detection
IG (Pin3) is used for ignition detection. It is strongly recommended to connect this pin to
ignition key “RU ” position as shown. If you do not connect the ignition detection, not all
functions of the device will be available.
An alternative to connecting to the ignition switch is to find a non permanent power source
that is only available when the vehicle is running. For example the power source for the
FM radio.
IG signal can be configured to start transmitting information to backend server when
ignition is on; and enter power saving mode when ignition is off.
3.9. Digital Inputs
There are three general purpose digital inputs on AVL300. They are all negative trigger.
