Controller Recovery

In the rare case that firmware on Expert Control becomes corrupted, there is a method to recover the controller using its memory card.

Please follow these instructions carefully:

  1. Remove the micro SD memory card from Expert Control and insert it into your computer.

  2. Wipe all files on the memory card (ensure you have made any necessary backups).

  3. Locate the firmware folder in the Expert installation location or app bundle (see below).

  4. Copy the file xpc.app from the firmware folder to the memory card.

  5. Reinsert the memory card into Expert Control and restart the controller. Expert Control will boot, but will take longer to boot than normal. Please be patient and wait for the Active LED to illuminate continuously.

  6. Connect to Expert Control using Expert software and reload the firmware as normal.

  7. Remove the memory card from Expert Control and insert it into your computer again.

  8. Delete the xpc.app file from the memory card.

  9. Reinsert the memory card into Expert Control and restart the controller.
