Write to device and wait for transfer to complete The new configuration will take effect at next power up Changing the firmware Go to www kae systems com and navigate to FlexControl 14 page Download the firmware version you want Firmware files have bin extension Download FlexControl configurator with the same version as the firmware file Bring back to mind instructions from previous chapter FlexControl configurator utility Open FlexControl configurator and click menu Update firmware A new dialog window will pop so You can enter a path to the downloaded firmware file Click button Go and wait to complete ee EE Troubleshooting During the update process the illuminated button will blink with fast rate If download has been successful the button will light on for 2 seconds then light off otherwise it will light on constantly and remain it this state If download fails or hasn t been started at all it could be because of You didn t connect the MIDI cable to FlexControl 14 The firmware is intended for other device Then you should correct preconditions and try again Supplying phantom power to pins 1 and 3 of the MIDI In jack Some MIDI devices can be powered through spare pins 1 and 3 of their MIDI Out jacks FlexControl 14 is ready to complement this feature by bridging its power sources DC power jack or DC internal connector to 4 jumper pads on its bottom sid
