Hi Paul, I just want to tell you that I fixed the problem. It seemed that there was a conflict between to Labview.dll. In the Directory of actiview software there is a copy of 49 KB while the copy in the USB Windows 32 bit->Developers kit->C-code path is 42 KB I copy the small file in the same path ...

Hi Paul, thanks very much for the quick answer. 1) I experienced the error you mentioned in a. 2) Windows xp 3) Yes, in the past I run other version of Biosemi but I also format it after I got a virus. 4) Yes it does. But what is strange is that Biosemi is not under USB controller tab but is mention...

Hi guys, I run into the same problem. As just Paul said

In Settings->Control Panel->System->Hardware->Device Manager,
I see "MS WinUsb2 Driver",

what does it mean? How I fix this problem in order to recognize the USB receiver?

Any help is very appreciate. Thanks in advance.

Hi, I would like to know if somebody experienced this problem with EEGlab. After loading my bdf file I can read from Matlab workspace "WARNING SOPEN: number of event onset (TYP=FF) and event offset (TYP=80FF) differ". What does it mean?Despite many efforts I don't really know where to pick up the so...

Hi, I read from different posts that the function keys F1-F8 are by standard coupled to trigger lines 9-16. A key press makes the respective trigger line high. Sounds good. I made and it works. What I'm still wondering is what does it mean that "the tringger length must be at least the duration of a...

big voltage value

Hi, I read careful what you suggest on http://sccn.ucsd.edu/pipermail/eeglablist/2005/000930.html as regard as the reference electrodes. For my experiment I have chosen to put CMS/DLR on the ears. So If I understood this means that the voltage I measure on Cz is the difference between the voltage on...

Biosemi software

Hi, Even I read many times on this topic ..I still have some doubts! :( Actiview has two counters running continuously: one counter tracks the total of the buffered words, the other counts the total of words displayed on screen (or written to file). The difference between the two counters is the "ba...

TCP connection

Thanks for the answer! As you mentioned all relevant controls grayed out when the system is running so I can't see the packet size of TCP/IP. You say that is constant but which is the relationship between the number channels and sampling rate to determine size of the packet. I mean, TCP array has a ...
