1. Introduction
The AVL-75 is a compact waterproof GPS tracker designed for a wide variety of vehicle tracking
applications. It has multiple I/O interfaces that can be used for monitoring or controlling external
devices. Its built-in GPS receiver has superior sensitivity and fast time to first fix. Its quad band
GPRS/GSM subsystem supports 850/900/1800/1900 MHz allowing the AVL-75's location to be
monitored in real time or periodically tracked by a backend server and mobile devices. Its built-in 3-axis
accelerometer allows motion detection and extends battery life through sophisticated power
management algorithms. System integration is straightforward as complete documentation is provided
for the full featured @Track protocol. The @Track protocol supports a wide variety of reports including
emergency, geo-fence boundary crossings, driving behavior, low battery and scheduled GPS position.

3. Getting Started
3.1. Install a SIM Card
Step 1: Remove the top cover.
Step 2: Insert the SIM card into the SIM card holder.
Step 3: Place the top cover on the bottom cover, and tighten both covers until they snap.
Note: Make sure that the seal ring is in place and there is no obvious gap between covers and seal
ring.

Step 4: Turn over the device and tighten the screw with screw cushion.
Step 5: Connect the device to extend cable. Or cut off the 8Pin Molex connector.
3.2. Switch on the Device
The method to power on AVL-75:
- Use external power to turn on.
When the external power is removed, AVL-75 will switch to internal backup battery and keep on
running. When internal backup battery is exhausted, AVL-75 will give a report and then turn off.
3.3. Power Connection
The red wire is power wire and the black wire is ground wire. 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.

3.4. Ignition Detection
Table 5: Electrical Characteristics of Ignition Detection
Figure 3. Typical Ignition Detection
The white wire is used for ignition detection. It is strongly recommended to connect this wire to ignition key at
“RUN” position as shown above.
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.Ignition signal can be
configured to start transmitting information to the backend server when ignition is on and enter power saving
mode when ignition is off.
3.5. Digital Input
There is a negative trigger input on the AVL-75.For negative trigger input the electrical conditions are:
Logical State

Active
0V to 0.8V
Inactive
1.7V to 32V or Open

The outputs are Open-Drain type with no internal pull-up resistor which can also be used to control a relay. It
means that the user has to connect a pull-up resistor or a relay coil between the output pin and any positive
voltage (32V max) to generate a correct output. Each output can drive a continuous current of 0.15A.
The green wire is low side 150mA max, and the blue wire is low side 150mA max with latch.
The electrical conditions are:
Table 7: Electrical Conditions of Digital Outputs
Note:
1. The relay output can be latched by the software, so even if the AVL-75 is restarted or powered down in
some cases, the relay output will not change. To use the latch function, the main power and backup battery
should be connected. Otherwise the relay will always be in normal close status.
Digital outputs are used for cutting/restoring GND. The examples of connections are:
Figure 5. The Example of Connection to Drive An LED
Figure 6. The Example of Connection to Drive A Relay
Note: All outputs are internally pulled up to PWR pin by a diode. So no external fly-back diode is needed
when the output is connected to an inductive load.

3.6. UART Interface
There is one UART interface on AVL-75. UART is used for configuration and firmware downloading, and
communicating with external devices like CAN Bus module and RFID reader.
Please note the UART interfaces are all RS232 level. For RS232 level, valid signals are 3V to 15V and -3V
to -15V and the -3V to +3V is not a valid level. 3V to 15V correspond with logic 0 of TTL level, while -3V
to -15V correspond with logic 1.
The examples of connections of UART with female DB-9 and with external devices are showed as
follows.

4. Troubleshooting and Safety Info
4.1. Troubleshooting
Trouble
Possible Reason
Solution
After AVL-75 is
turned on, the
CELLED always
flashes quickly.
The SIM card is not inserted.
Please insert the SIM card into
AVL-75.
The signal is too weak; AVL-75
cannot register to the network.
Please move AVL-75into places
with good GSM coverage.
The SIM card is PIN locked.
Use SIM card without SIM PIN, or
unlock SIM PIN.
Messages can’t be
reported to the
backend server by
GPRS.
The SIM card in AVL-75 does not
support GPRS.
Try a GPRS supporting SIM card.
APN is wrong. Some APNs cannot
visit the Internet directly.
Ask the network operator for the
right APN.
The IP address or port of the
backend server is wrong.
Make sure the IP address for the
backend server is an identified
address on the Internet.
AVL-75 doesn’t
power off.
The function of power key is disabled
by AT+GTSFR.
Enable the function of power key
by AT+GTFKS.
AVL-75 can’t get
successful GPS
fixing.
The GPS signal is weak.
Please move AVL-75 to a place with
open sky.
It is better to let the top surface
face the sky.
4.2. Safety Info
Please do not disassemble the device by yourself.
Please do not put the device in an over-heated or too humid place, and avoid exposure to direct
sunlight. Too high temperature will damage the device or even cause battery explosion.
Please do not use AVL-75 on an airplane or near medical equipment.
