Test it in Windows PC

1. Download and install u-center software and then open it
2. Set the jumpers on A area, assemble GNSS antenna,and set the receiver of antenna on open area outside. Connect the micro USB interface to PC
3. Note that you should set the side without sticker upward, Open Device Manager and check the COM port, connect MAX-M8Q, and use auto-baudrate
4. Power the MAX-M8Q module and set it to 3D mode, select File ->Database Export ->Google Map Html to export file
5. Download Test file, upzip and open it by Chrome browser, import the file which is saved from u-center above to check position information.
6. Please refer to the User guide about how to use the u-center.
