Introduction
The GV600WG is a compact waterproof GPS trackers designed for a wide variety of vehicle tracking applications. They have multiple I/O interfaces that can be used for monitoring or controlling external devices, including a 1-wire interface used for temperature monitoring. Bluetooth 4.2 is supported. Virtual ignition detection and iButton function are both supported. Their built-in GPS receiver has superior sensitivity and fast initial positioning. Different models allow the GV600WG’s location to be monitored in real time or periodically tracked by a backend server or mobile devices. System integration is straightforward as complete documentation is provided for the full featured @Track protocol. The @Track protocol supports a wide variety of reports such as emergency, geo-fence boundary crossings, and external power supply monitoring and scheduled GPS position reports.

Getting Started
Open and Close the Case

- To open: Use a cross screwdriver to loosen the four screws and then lift the top case gently.
- To close: Align the top case with the bottom case and then tighten the four screws.
Note:
Pay attention to the following details to close the case. Otherwise, the waterproof capability of the device may be deteriorated.
- The positioning poles (total 11) on the top cover must be inserted into the holes of the rubber ring as shown below.

- Tighten the screws sufficiently until the rubber ring is squeezed out as shown in the following figure 1.

Install a SIM Card
Open the case and ensure the unit is powered off (unplug the 18-pin cable and switch the internal battery to the OFF position). Insert the SIM card into the holder. Take care to align the cut mark and ensure the SIM card is pushed into the SIM holder completely. Close the case.

Install the Internal Backup Battery and Close the Case
GV600WG has an internal backup Li-ion battery (5200mAH).

Power Supply Connection
PWR (pin 1 or pin 2)/GND (pin 3 or pin 4) are the power input pins. The input voltage range is from 8V to 32V. The device is designed to be installed in vehicles that operate on 12V or 24V systems without the need of external transformers.

Ignition Detection
Table 7. Electrical Characteristics of Ignition Detection
| Logical Status | Electrical Characteristics |
| Active | 5V to 32V |
| Inactive | 0V to 3V or open loop |

IGN (pin 5) is used for ignition detection. It is recommended to connect this pin to the “RUN” position of the vehicle ignition switch as shown above.
An alternative to connect 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 to transmit information to the backend server when ignition is on and enter the power saving mode when ignition is off.
Digital Inputs
There are four general purpose digital inputs on GV600. They all are negative triggers.
Table 8. Electrical Characteristics of the Digital Inputs
| Logical Status | Electrical Characteristics |
| Active | 0V to 0.8V |
| Inactive | Open loop |
The following picture shows the recommended connection of a digital input.

Analogue Inputs
There is one analogue input on GV600WG, and the analogue input voltage range is from 0 to 32V. The following picture shows the recommended connection.

Note:
Pin 6 is a multifunction pin: it can be configured as an analogue input.
Digital Outputs
There are four digital outputs on GV600WG. All are of open drain type and the maximum drain current is 150 mA. Each output has a built-in over current PTC resettable fuse.

Table 9. Electrical Characteristics of Digital Outputs
| Logical Status | Electrical Characteristics |
| Enable | <1.5V @150 mA |
| Disable | Open drain |

Typical Connection with Other Devices
Note:
Pay attention to the polarity of the relay if it is pre-installed with an internal flyback diode during connection. Install an additional diode externally if there is no pre-installed internal diode. A common diode such as a 1N4004 one will work in most circumstances.
