Firmware Flashing

Important Notes

1. During flashing, connect the main control board to your computer using a USB-C data cable.
2. During flashing, disconnect the 24V power input from the main control board. Otherwise, unexpected behavior may occur.
3. For the first-time flashing, you must erase the Flash using the corresponding tool. Otherwise, flashing may fail.
4. When updating to a newer firmware version, do not erase Flash again, or your custom configuration data will be lost.

Pre-Flash Checklist

• Ensure the USB-C cable is a data cable, not power-only.
• Power off 24V and keep USB power only.
• Extract the firmware archive and prepare the three .bin files.

Troubleshooting

• No serial port: try another USB cable or USB port.
