GV300VC User Manual
1. Introduction
The GV300VC is a compact 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 dual band CDMA2000-1x
allows the GV300VC'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 driving behaviour monitoring,
motion detection and extended 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 behaviour, low battery and scheduled GPS position.

3.3 Install the Internal Backup Battery
Figure 5. Backup Battery Installation
GV300VC has an internal backup Li-ion battery.
3.4 Switch on the Backup Battery
To use the GV300VC backup battery, the switch must be in the ON position. The switch on the case
and the ON/OFF position are shown below.
Figure 6. Switch and ON/OFF position
Note:
1. The switch must be in the “OFF” position when the GV300VC is shipped on an aircraft.
2. When the switch is in the “OFF” position, the battery cannot be charged or discharged.

3.5 Install the External GPS Antenna (Optional)
There is a SMA GPS antenna connector on GV300VC. The GV300VC will automatically detect and
use an external antenna when connected.

3.6 Power Connection
PWR (PIN12)/GND (PIN6) is the power input pin. 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.

Figure 9. 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 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. IGN
signal can be configured to start transmitting information to the backend server when ignition is on,
and enter the power saving mode when ignition is off.
There are three general purpose digital inputs on GV300VC. They are all negative trigger.

3.9 Analog Inputs
There are two analog inputs on GV300VC, and the analog input voltage range is from 0 to 16V.
The following diagram shows the recommended connection.

Note:
PIN 15 is a multifunction pin: it can be configured as a digital input or an analog input.
3.10 Digital Outputs
There are three digital outputs on GV300VC. All are of open drain type and the maximum drain
current is 150 mA. Each output has the built-in over current PTC resettable fuse

Figure 13. Typical Connection with Relay
Figure 14. Typical Connection with LED
Note:
1. OUT1 will latch the output state during reset.
2. Many modern relays come with a flyback diode pre-installed internal to the relay itself. If the
relay has this diode, ensure the relay polarity is properly connected. If this diode is not internal,
it should be added externally. A common diode such as a 1N4004 will work in most circumstances.
