1. Introduction
The GV57MG V2 is a compact GNSS vehicle tracking device that supports EGPRS and
LTE Cat M1/NB2. It is designed for a wide variety of applications such as stolen vehicle
recovery, motorcycle monitoring and other basic tracking applications. The built-in GNSS
receiver has superior sensitivity and fast initial positioning. The full-featured @Track Air
Interface Protocol provides the complete documentation, so it's easy to learn system
integration. The protocol supports a wide variety of reports including emergency alarm,
geo-fence boundary crossings, external power supply monitoring and position reports.

3. Getting Started
3.1 Installing a SIM Card
Step 1
Open the top cover.
Note: Please unplug the 5-PIN pitch connector cable and make ensure the device is not
powered up. Don’t disassemble the device repeatedly, otherwise it may affect the
waterproof performance of the device.
Step 2
Make sure the small notch in the corner of the SIM card matches the one in the SIM card
tray so that it fits properly. The words or logo on the SIM card should be facing up. Slide
the SIM card tray back into the SIM card slot.
Step 3
Press to close the top and bottom covers until you hear a snap. Make sure that there is a

Step 4
Screw down the device covers.
3.2 USB Interface
The GV57MG V2 has a USB interface that is used for firmware download by using the
USB cable .

3.3 UART Interface
The GV57MG V2 has an optional UART cable for configuration. The physical interface
used by it is the same as that used by as the USB interface.
Note: The UART cable and USB cable of the GV57MG V2 are oriented when plugged into
the corresponding connector. The cables need to be vertically down and the connector
direction of the cables needs to be as shown below.

3.4 Power Connection
The PIN 2 (VIN, red) and the PIN 3 (GND, black) are used for power input. The power
source you connect to the PINs has to be 8V to 32V for the GV57MG V2 to work. The
device is designed to be installed in vehicles that operate on 12V/24V systems without the
need to use external transformers.

3.5 Ignition Detection
Table 5: Electrical Characteristics of Ignition Detection
Logical Status Electrical Characteristics
Active 5.0V to 32V
Inactive 0V to 3V or open
Figure 4. Typical Ignition Detection
The PIN 5 (IGN, white) is used for ignition detection. We recommend that you connect it to
the RUN position of the vehicle ignition switch as shown (Figure 4).
If you look for an alternative, we recommend that you find a power source that is available
only when the vehicle is started, for example, the power source for the FM radio. The
device will send messages to the backend server as the IGN signal completes
configuration when the ignition is on, and switch to the power saving mode when the
ignition is off.
3.6 Digital Input
There is one general purpose digital input on GV57MG V2. It is a negative trigger.

Figure 7. Typical Connection with a Relay
Note:
1. Many modern relays already have the freewheeling diodes inside. If the relay has this
diode, make ensure the polarity of the relay is connected correctly when using it. If not built
in, the diode should be added outside the relay. A common diode such as a 1N4004 will
work in most circumstances.
3.8 LED Status
The GV57MG V2 has two status LEDs that are Cellular LED and GNSS LED respectively.
