M3 User Guide
M3 Key Setup Method
To extend the lifespan of the function key, the function key at the upper right of the M3 uses a flat-panel design. For users who find it difficult to press, we provide the following key change guide to help make use more comfortable.
The M3 key layout is as shown in the image. It is convenient to change key 24 (UP) and key 22 (RS) to keys often used in training mode.
Key Configuration Steps
While holding the Start button at the upper right (or upper left), connect the device to your computer to enter configuration mode.
After connecting to your computer, enter “192.168.7.1” in the navigation bar of your browser (Google Chrome recommended) to open the settings screen.
After entering the settings screen, click “Configuration” - “GPIO Pin Mapping” at the top and find “24” and “22”. First, delete the existing mappings, then click the drop-down window to add the mappings you want. When the changes are complete, click “Save” at the bottom, then click the green “Reboot” button in the upper right. After that, click “Controller” to complete reconnection.
