Getting Started
Installing a SIM Card
Step 1: Remove the top cover (ensure the device is not powered unplug the
5 Pin cable and turn off the battery).
Note: Waterproof equipment. Don’t disassemble repeatedly.
Step 2: Put the SIM card into the SIM card holder. Press down on the SIM
card slightly to make it slide into the slot.
Step 3: Place the top cover on the bottom cover, and tighten both covers
until they snap.Make sure that the seal ring is in place and there is no
obvious gap between covers and seal ring.
Step 4: Turn over the device and tighten the screws with screw cushion.
UART Interface
There is a UART interface on GV57MG used to connect to GV57MG UART Cable 0.5M.
UART is used for configuration. The UART interface and USB interface use
thesame physical interface.
USB Interface
GV57MG has one USB interface which uses the same physical interface as UART
interface. It is used for firmware download.
Power Connection
PWR (VCC, Red) / GND (Black) 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/24V vehicle without the need for external
transformers

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
IGN (White) is used for ignition detection. 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 for the device to start transmitting information to the backend server when the ignition is on, and enter the power saving mode when the ignition is off
Digital Input
There is one general purpose digital input on GV57MG. It is a negative trigger.

Logical Status | Electrical Characteristics |
---|---|
Active | 0V to 0.8V |
Inactive | Open |

Digital Output
OUT (Brown) is a digital outputon GV57MG. It is of open drain type and the maximum drain current is 150mA.

Index | Description | Remark |
---|---|---|
1 | Enable | <1.5V @ 150mA |
2 | Disable | Open drain |
Figure 7.Typical Connection with a Relay
Note:
- Many modern relays come with a fly backdiode pre-installed internal to the relay itself. If the relay has this diode, ensure the relay polarity is properly connected. If this diode is not internal, it should be added externally. A common diode such as a 1N4004 will work in most circumstances.
LED Status
GV57MG has two status LEDs that are CELL LED and GNSS LED.
Figure 8. GV57MG LEDs on the Case
Table 8. Definition of Device Status and LED
LED | Device Status | LED Status |
---|---|---|
CELL LED (Green) | The device is searching cellular network. | Fast flashing |
The device has been registered to cellular network. | Slow flashing | |
SIM card needs pin code to unlock. | ON | |
GNSS LED (Red) | GNSS is turned off. | OFF |
The device has got GNSS location information. | ON | |
The device is searching for GNSS signal. | Fast flashing | |
GNSS sends no data or data format error occurs. | Slow flashing |
Note:
- The fast flashing of cell led is about 100ms ON/800ms OFF.
- The slow flashing of cell led is about 100ms ON/2000ms OFF.
- The fast flashing of GNSS led is about 100ms ON/100ms OFF.
- The slow flashing of GNSS led is about 600ms ON/600ms OFF.
Motion Sensor Direction
GV57MG has an internal 3-axis accelerometer supporting motion detection. The
following shows the directions of the motion sensor. The z-axis points
vertically inward.

Troubleshooting and Safety Information
Troubleshooting
Problem | Possible Reason | Solution |
---|---|---|
After GV57MG is turned on, the CELL LED always flashes quickly. | The signal is | |
too weak; GV57MG cannot be registered to the network. | Please move GV57MG into |
places with good network coverage.
Messages cannot be reported to the backend server.| The IP address or port of
the backend server is wrong.| Make sure the IP address for the backend server
is an identified address on the internet.
GV57MG cannot power off.| The device is connected to ignition wire.|
Disconnect ignition wire, and try again.
GV57MG cannot get successful GNSS fix.| The GNSS signal is weak.| Please move
GV57MG to a place with open sky.
It is better to let the surface (without LED indicators) face the sky.
Safety Information
- Do not disassemble the device by yourself.
- Do not put the device in overheated, too humid place, and avoid exposure to direct sunlight. Too high temperature will damage the device or even cause battery explosion.
- Do not use GV57MG on airplane or near medical equipment.
