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 ... -

Page 13: Digital Output
GV75W User Manual 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 Electrical State Enable <1.5V, drive current is 0.15A Disable 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 ... -

GV75W User Manual 3.7. 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 ... -
