History

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, extemal power supply monitoring and position reports.

User Cable|
GV57MG V2 UART Cable (Optional)|
GV57MG V2 USB Cable (Optional)|

Note: The GV57MG V2 UART cable and the USB cable are optional accessories and may not be delivered along.
2.3 Interface Definition
The GV57MG V2 has a 5-PIN pitch connector cable that is used to connect to the power and I/Os. You can find the cable in Figure 2, and its sequence and description in Table 4.

Table 4: Description of 5-PIN Connections

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 30 that it fits property. 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 tight fit between the covers and the seal ring. 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 itis 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 GV357MG 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

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 altemative, 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 wil 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.
Table 6: Electrical Characteristics of Digital input

3.7 Digital Output
The PIN 4 (OUT, brown) is an open-drain digital output. The maximum drain current for the device is 150mA Table 7: Electrical Characteristics of Digital Output

Note:

1. Many modem 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. Table 8. Definition of Device Status and LED

The device is connected to another device via Bluetooth for the first time, when is set by the AT+GTSVR command.| 2000ms
ON/2000ms
OFF (last 40s)
GNSS LED (Red)| GNSS is turned off.| OFF
The device has got GNSS location information.| Solid red
The device is searching for GNSS signal.| Fast flashing
GNSS sends no data or data format error occurs.| Slow flashing

Note:

1. The fast flashing of the Cellular LED is about 100ms when the LED indicator is on and 800ms when it is off.
2. The slow flashing of the Cellular LED is about 100ms when the LED indicator is on and 2000ms when it is off.
3. The fast flashing of the GNSS LED is about 100ms when the LED indicator is on and 100ms when it is off.
4. The slow flashing of the GNSS LED is about 600ms when the LED indicator is on and 600ms when it is off.

3.9 Motion Sensor Direction
The GV57MG V2 has an internal 3 axis accelerometer that supports motion detection. The following screenshot shows the directions of the motion sensor. The z-axis points vertically inward.

Troubleshooting and Safety Information

4.1 Troubleshooting

cellular signal strength is weak; Or
2. The device isn’t registered on network.| Please place the device in an area with good network coverage.
Messages can’t be reported to the backend server.|  The IP address or port of the backend server is wrong.| Please check and make sure the IP address is identified by the internet.
The device can’t power off.| The device is connected to the ignition wire.| Please disconnect the ignition wire and try again.
The device can’t get successful GNSS fix.| The GNSS signal is weak.| 1. Please place the device in an open area. Or
2. Let the side without LED indicators face up.

4.2 Safety Information

• Don’t disassemble the device by yourself.
• Don’t place the device in an environment with high temperature and high humidity. Avoid exposure to direct sunlight. The high temperature will damage the device and even cause a battery explosion.
• Don’t use the device on the airplane or near the medical equipment.
