Introduction
The GV75W is a compact waterproof GPS tracker designed for a wide variety of vehicle tracking applications. It has multiple I/O interfaces that can be used for monitoring or controlling external devices. Its built‐in GPS receiver has superior sensitivity and fast time to first fix. Its triple band
WCDMA subsystem supports UMTS/HSDPA 850 (Band V)/1900 (Band II)/2100 (Band I) MHz and quad band GSM/GPRS 850/900/1800/1900 MHz, allowing the GV75W's location to be monitored in real time or periodically tracked by a backend server and mobile devices. Its built‐in 3‐axis accelerometer allows motion detection and extends battery life through sophisticated power management algorithms. System integration is straightforward as complete documentation is provided for the full
featured @Track protocol. The @Track protocol supports a wide variety of reports including emergency, geo‐fence boundary crossings, driving behavior, low battery and scheduled GPS fix.

Getting Started
3.1.
Install a SIM Card
Step 1:
Remove the top cover.
Step 2:
Insert the SIM card into the SIM card holder. Note: 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.
Note:
Make sure that the seal ring is in place and there is no obvious gap between covers and seal ring.
TRACGV75WUM001 ‐ 9 ‐
GV75W User Manual
Step 4:
Turn over the device and tighten the screw with screw cushion.
Step 5: Connect the device to extension cable or cut off the 12Pin Molex connector.
3.2.
Switch on the Device
The method to power on GV75W: Use external power to turn on.
When the external power is removed, GV75W will switch to internal backup battery and keep on running. When internal backup battery is exhausted, GV75W will report a message and then turn off.
3.3.
Power Connection
The red wire is power wire and the black wire is ground wire. 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 or 24V systems without the need for external transformers.

Table 6: Electrical Characteristics of Ignition Detection
Figure 3: Typical Ignition Detection
The white wire is used for ignition detection. It is strongly recommended to connect this wire to ignition key at “RUN” position as shown above.
An alternative to connecting to the ignition switch is to find a non‐permanent power source (like the power source for FM radio) that is only available when the vehicle is running. Ignition signal can be configured to start transmitting information to the backend server when ignition is on and to enter
power saving mode when ignition is off.
3.5.
Digital Input
There is a negative trigger input on GV75W. For negative trigger input, the electrical conditions are as follows:
Logical State
Active
Inactive
Electrical State
0V to 0.8V
1.7V to 32V or Open

The connection is shown as follows:

3.6.
Digital Output
The outputs are Open‐Drain type with no internal pull‐up resistor which can be used to control a relay.
It means that the user has to connect a pull‐up resistor or a relay coil between the output pin and any positive voltage (32V max) to generate correct output. Each output can drive a continuous current of 0.15A.
The green wire is low side 150mA max, and the blue wire is low side 150mA max with latch.
The electrical conditions are shown in the following table:
Logical State
Enable
Disable
Electrical State
<1.5V, drive current is 0.15A
Open or the pull‐up voltage (max 32V)
Table 8: Electrical Conditions of Digital Outputs
Note:
The relay output can be latched by the software, so even if the GV75W is restarted or powered down in some cases, the relay output will not change. To use the latch function, the main power and backup battery should be connected. Otherwise the relay will always be in normally closed state.
Digital outputs are used for cutting/restoring GND. The connections are shown below.
Figure 5: Connection to Drive an LED
Figure 6: Connection to Drive a Relay
Note: All outputs are internally pulled up to PWR pin by a diode. So no external flyback diode is needed when the output is connected to an inductive load.

UART Interface
There is one UART interface on GV75W. UART is used for configuration, firmware download, and communicating with external devices such as CAN Bus module and RFID reader.
Please note the UART interfaces are all RS232 level. For RS232 level, valid signals are 3V to 15V and ‐
3V to ‐15V, and the ‐3V to +3V is not a valid level. 3V to 15V corresponds with logic 0 of TTL level, while ‐3V to ‐15V corresponds with logic 1.
The examples of connections of UART with female DB‐9 and with external devices are shown as follows.
Figure 7: The Connection of UART with Female DB‐9
Figure 8: The Connection of UART with External Devices
3.8.
USB Interface
Gv75W has one USB interface which is used for
firmware download and connects to the
GV75W_UART_USB_PWR_Convert_CABLE (optional)
. The
GV75W_UART_USB_PWR_Convert_CABLE is used when downloading the firmware.

Troubleshooting and Safety Info
4.1.
Troubleshooting
Trouble
After GV75W is turned on, the CEL
LED always flashes quickly.
Possible Reason
The SIM card is not inserted.
The signal is too weak; GV75W can’t register to the network.
The SIM card is PIN locked.
Solution
Please insert the SIM card into
GV75W.
Please move GV75W into places with good GSM coverage.
Use SIM card without SIM PIN, or unlock SIM PIN.
Try a GPRS supporting SIM card. Messages can’t be reported to the backend server by
GPRS.
The SIM card in GV75W doesn’t support GPRS.
APN is wrong. Some APNs cannot visit the Internet directly.
The IP address or port of the backend server is wrong.
GV75W doesn’t power off.
The function of power key is disabled by AT+GTSFR .
Ask the network operator for the right APN.
Make sure the IP address for the backend server is an identified address on the Internet.
Enable the function of power key by
AT+GTFKS .
GV75W can’t get successful GPS fix.
The GPS signal is weak. Please move GV75W to a place with open sky.
It is better to let the top surface face the sky.
