GV304N User Manual
1. Introduction
The GV304N 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
GSM850/GSM900/DCS/PCS. Its location can be monitored in real time or periodically tracked by
a backend server or other specified terminals. The GV304N has multiple input/output interfaces
that can be used for monitoring or controlling external devices. Based on the integrated @Track
protocol, the GV304N can communicate with a backend server through the GPRS/GSM network
to transfer reports of emergency, geo-fence boundary crossings, low backup battery and scheduled
GPS position as well as many other useful functions. Users can also use GV304N to monitor the
status of a vehicle and control the vehicle by its external relay output. System integrators can
easily set up their tracking systems based on the full-featured @Track protocol.
WARNING: This device complies with part 15 of the FCC Rules. Operation is subject to the
following two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that may cause
undesired operation.
Changes or modifications not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
FCC RF Exposure Statement:
For the product, under normal use condition is at least 20cm away from the body of the user,
the user must keeping at least 20cm distance to the product.

3. GettingStarted
3.1. Opening the Case
Figure 3.Opening the Case
As shown, Roll the four screws counter clockwise with a screwdriver ,you can easily open
the product.
3.2. Closing the Case
Figure 4.Closing the Case
Place the cover on the bottom in the position as shown in the following figure. Use a screwdriver
clockwise to tighten four screws.
3.3. Installing a SIM Card 
Open the case and ensure the unit is not powered (unplug the 16Pin cable and switch the internal
battery to off position). 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

3.5. Switch ON the Backup Battery
To use the GV304N backup battery, the switch must be at the ON position. Switch on the case and
ON/OFF position are shown below.
Figure 7.Switch and ON/OFF position
Note:
1. The switch must be on the “OFF” position when shipped on an aircraft.
2. When the switch is on the “OFF” position, the battery cannot be charged or discharged.
3.6. Installing the External GPS Antenna (Optional)
There is a SMA GPS antenna connector on GV304N. The GV304N will automatically detect and
use an external antenna when connected.

3.7. Power Connection
PWR (PIN11) / GND (PIN6) 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.

Figure 10. 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 backend server when ignition is
on; and enter power saving mode when ignition is off.
There are three general purpose digital inputs on GV304N. They are all negative trigger.

Note:
PIN 15 is an multifunction pin: it can be configured as a digital input or an analog input.
3.11. Digital Outputs
There are three digital outputs on GV304N. All are of open drain type and the maximum drain
current is 150 mA. 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 pulled up to PWR pin by a diode. So no external flyback diode is
needed when the output is connected to an inductive load.
