Introduction

The GV57CG is a compact GNSS vehicle tracking device that supports EGPRS and LTE Cat 1. 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.

Note : The GV57CG USB_Cable_1M is an optional accessory and may not be deliver along.

Interface Definition
The GV57CG has a 5-PIN pitch connector cable for connecting power and I/O. Please
view the following Figure 2 and Table 4 for details.

Get Started

Install a SIM

Step 1
Open the top cover.

Note : Please unplug the USB cable and ensure that the device is not powered on.

DO NOT disassemble the device repeatedly, otherwise, the waterproof performance of the device may be affected.

Step 2
Make sure the small notch in the corner of the SIM card matches the one in the SIM card cray so that it fits properly. Place the words or logo side of the SIM card facing up. Then 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 rin

Step 4
Tighten the screws on the four corners with the screwdriver to close the device.

USB Interface
The GV57CG has a USB interface that is used for firmware download by using theSB_Cable_1M.

Note : Make sure that the USB cable of the GV57CG is oriented correctly when plugged  into the corresponding connector. The cable should be vertically down, as shown in the following figure

Power Connection
PIN 2 (VIN, red) and PIN 3 (GND, black) are used for power input. The power supply connected to the PIN must be 9V to 90V for the GV57CG to work properly.

Ignition Detection

If you are looking for an alternative, we recommend that you find a power source that is only available when the vehicle is started, such as a 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.

Digital Input/Analog Input
There is an input on the GV57CG that can be configured as an analog input or a digital
input.
For the digital input , it is a negative trigger.
For the analog input, the range of input voltage is from 0V to 16V.

Digital Output
PIN 4 (OUT, brown) is an open-drain digital output. The maximum drain current for the
device is 150mA.

Note:
Many modern relays already have the freewheeling diodes inside. If the relay has this diode,
make sure 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

LED Status
The GV57CG has two status LEDs, namely Cellular LED and GNSS LED.

Note

1. The fast flashing of the Cellular LED is about 100ms when the LED is on and 800ms
   when it is off.

2. The slow flashing of the Cellular LED is about 100ms when the LED is on and 2000ms when it is off.

3. The fast flashing of the GNSS LED is about 100ms when the LED is on and 100ms
   when it is off.

4. The slow flashing of the GNSS LED is about 600ms when the LED is on and 600ms
   when it is off.

Motion Sensor Direction
The GV57CG has an internal 3-axis accelerometer that supports motion detection. The following figure shows the directions of the motion sensor. The Z-axis points vertically up

Troubleshooting and Safety Information

Troubleshooting

1. The cellular signal strength is weak.
2. The device isn’tregistered on the 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 iswrong.| Please check and make sure the IP address isidentified by the Internet.
The device can’t bepowered off.| The device is connectedto the ignition wire.| Please disconnect theignition 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.

2.  Let the side without LED face up.
