Not Railed Error in OpenBCI GUI

in Cyton

Hi there,

I am connecting my Cyton board with 4 electrodes following this tutorial: https://docs.openbci.com/AddOns/Headwear/HeadBand/; however, my electrodes are placed in the following 10 20 system.

The issue is that on the OpenBCI GUI, I always see a message near the graph saying 'Not Railed' or 'Near Railed'. I am confident that the electrodes are making contact with my head, but on the Cyton Dongle, the TXD light is flashing red - I don't know if this means something.... This is the error message, along with the wiring:


Does anyone know a possible solution?

Thanks in Advance!
