1Introduction
The GV55 is a powerful GPS locator designed for vehicle or asset tracking. It has superior
receiver sensitivity, fast TTFF (Time to First Fix) and supports Dual-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 GV55 has
multiple input/output interfaces that can be used for monitoring or controlling external
devices. Based on the integrated @Track protocol, the GV55 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 GV55 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.

Place the cover on the bottom in the position as shown in the following figure. Slide the
cover against the direction of the arrow until it snapped.
Open the case and ensure the unit is not powered (unplug the 6Pin cable). Slide the
holder right to open the SIM card. Insert the SIM card into the holder as shown below with
the gold-colored contact area facing down taking care to align the cut mark. Close the SIM
card holder. Close the case.
Figure 5. SIM Card Installation
PWR (PIN1) / GND (PIN2) 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.

Active 5.0V to 32V
Inactive 0V to 3V or Open
Figure 7. Typical Ignition Detection
IGN (Pin3)is used for ignition detection. It is strongly recommended to connect this pin to
ignition key “RUN” position as shown up.
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.
IGN signal can be configured to start transmitting information to back-end server when
ignition is on; and enter power saving mode when ignition is off.
There are one general purpose digital inputs on GV55. They are all negative trigger.

There are two digital outputs on GV55. All are of open drain type and the maximum drain
current is 150mA. Each output has the built-in over current and recovery PTC fuse

Note:
1 - OUT1 will latch the output state during reset.
2- All outputs are internally without pulled up to PWR pin by a diode. So an external
flyback diode is needed when the output is connected to an inductive load.
