Accelerometer data streams but no EEG
Hi. I bought a used Mark IV from Ebay. The seller claims the system was working when they shipped it. It came with Cyton, daisy chain (16 chans) and the wifi shield. Everything powers up (blue lights, etc) and I can connect to the GUI via Cyton with 8-channels. The accelerometer data streams and responds to physically moving the board. However, the EEG channels show no data either when the electrodes are on my head or when I touch the inputs per the install instructions. Also, when I try plugging in the daisy chain board, GUI says "Daisy is not attached to Ctyon board..."
I have tried on two PCs and one Mac computer. Same issues. Did I buy a lemon?
