catEEG and bwview showing strange data and 50hz noise?

Hello everyone,

I'm having this weird problem with my brand new olimex device while trying
to see some recording via bwview and recording it with catEEG.

I use these steps to view the current recording:

1) open a command window.  CD c:\path\to\cateeg folder.
   Run cateeg like this, e.g.:
cateeg > c:\temp\eeg.dat            [ reads from COM1 ]
or cateeg -p COM2 -f c:\temp\eeg.dat   [ reads from COM2 ]

2) open another command window.  CD c:\path\to\bwview
   Run bwview in "follow mode" like this:
bwview -c F mod/256 c:\temp\eeg.dat

And what I got as a results looks like this:

So there is this huge amount of noise in higher frequency bands. Is this
similar to anyones experience with these?

I also get this kind of reading from electric guru:

Which I suppose has something like 50hz noise a lot and some noise also at
lower frequencies. I'd be interested to fix this. Is there some steps to
accomplish proper signal?

Thanks!
