Working with windows

1. Download and install u-centersoftware, then open the u-center
2. Set the jumpers in A area, connect GNSS antenna,Put the receiver of the antenna in an open area outside for receive GPS signal, Connect the Module to PC by Micro USB cable
3. Note that you need to set the side of the antenna without sticker upward, check the COM port in Device Manager. Use the u-center to connect MAX-M8Q by select the COM port and select auto baud rate.
4. Enable 3D mode and export the file by selecting File -> Database Export -> Google Map Html.
5. Download Text_Release software and unzip. Open the file by Chrome, then import the HTML file which we saved above to check the position.
6. For detailed information about the u-center software, please refer to User guide MAX-M8Q GNSS HAT 002.jpg MAX-M8Q GNSS HAT 003.jpg MAX-M8Q GNSS HAT 005.jpg MAX-M8Q GNSS HAT 004.jpg
