After unpacking your decoder, this is what you need to do to get started quickly!

  1. Plug the decoder into a 2.5A or 3A power supply. We advice not using an extension cable, as it often limits the output.
  2. Wait about a minute to start everything up.
  3. Connect your presentation device (ie. laptop) to the wifi created by the decoder called 'mindaffect_test'.
  4. Navigate to http://10.0.0.5 on your presentation device.
  5. Update software by following the Update guide.
  6. Turn on your Ganglion, the blue light should blink (if not, break the connection with the device it is connected to).
  7. Fill in the MAC address of your Ganglion (with the ':' in between the two digits/letters), if you do not know the MAC address, use the 'blescan' button of the website. It should state the MAC address with the name ganglion-***.
  8. Let the decoder restart automatically and wait for the light of your Ganglion to be steady. Your Ganglion is now streaming to the BCI decoder.
  9. Make sure the sliders of the Ganglion are all away from the electrodes (so not lines up to the wide line) - the sliders are covered with a plastic protection layer when you receive the ganglion.
  10. Connect the green connector with 'BCI top'-text facing upwards to the output pins of the Ganglion board.
  11. Connect the electrodes to the Ganglion and put the MindAffect headset on your head, or put the electrodes on the right places on the back of the head. Please refer to the headset repository for more instructions.
  12. Download the repository of choice through github.com/mindaffect (ie. Python, Unity).
  13. If you install Python, you can view the signals and their qualities by starting the sigViewer in the mindaffectBCI/examples/utilities folder.
  14. To test the system, you can try running one of the ready-to-go programs, such as 'minimal_presentation.py'(in the examples of the Python module or download the MindAffect Speller from the iPad store.

Your Ganglion will stay connected to the decoder upon restart, so you will not have to do that again. To quickstart in the future, you can follow the Quickstart guide.
