1. Introduction
The GV50VC 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 CDMA2000-1x
frequencies 800/1900, its location can be monitored in real time or be periodically tracked
by a backend server or other specified terminals. The GV50VC has multiple input/output
interfaces that can be used for monitoring or controlling external devices. Based on the
integrated @Track protocol, the GV50VC can communicate with a backend server through
the CDMA2000-1x 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 GV50VC 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.

Note:
1 –CELL LED cannot be configured.
2 - GPS LED can be configured to turn off after a period of time using the configuration tool
3 - Fast flashing is about 60ms ON/ 780ms OFF
4 - Slow flashing is about 60ms ON/ 1940ms OFF
5 –When LED ON is 0, each time the device powers on, both LED’s will work for 30 minutes
and then are turned off deadly
2.4. Power Connection
VIN(PIN3)/GND(PIN7) are the power input pins. The input voltage range for this device is
from 8V to 16V. The device is designed to be installed in vehicles that operate on 12Vvehicle
without the need for external transformers.

Figure 3: Typical Power Connection
2.5. Ignition Detection
IGN (Pin4) 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 backend server when ignition is
on, and enter power saving mode when ignition is off.
