Manual bootloader mode for Mk1

If you have older version of firmware or if you constantly get “Firmware update FAILED” or “Not in firmware mode” message then you must put controller into firmware bootloader mode manualy:

1. Connect controller to computer with USB cable.
Controller has blinking LED which indicates that controller is working properly.

2. Press and hold “reset” button (or disconnect power) and place jumper or create shortcut on “Jog8” pin (this is between RB4 and VCC)).
This it second pin from right – see image. If you have jogging keys connected to controller you can press and hold “Jog8” button.
