Interface Definition

GV57MG has a 5-Pin cable. The figure of the 5-Pin cable is shown below.

Figure 2. GV57MG 5-Pin Cable

Table 4: Description of 5-pin Connections

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
Figure 3. Typical Power Connection

Ignition Detection

Table 5: Electrical Characteristics of Ignition Detection

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.

Table 6: Electrical Characteristics of Digital Input

Figure 5.Typical Digital Input Connection

Digital Output

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

Figure 7.Typical Connection with a Relay

Note:

1. 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

Note:

1. The fast flashing of cell led is about 100ms ON/800ms OFF.
2. The slow flashing of cell led is about 100ms ON/2000ms OFF.
3. The fast flashing of GNSS led is about 100ms ON/100ms OFF.
4. 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

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.
