I am a newbie to using your acquisition system. I trying to use the biosemi recording box based on PCI-interface (rather that the USB) to captuer data from 128 channels for ECG measurement. I am only trying to read data from the box but for some reason (that I am dying to know) I can't. I tried starting with one of the DI examples in Labview (in different modes: pattern I/O, handshaking cont. and buffered, burst) but I still get no data (read DI returns array of size 0) and the buffer is not emptied (I can tell that by the error LED in the buffer device between the DI card and the box). I also tried to sneak a peak at how your Actiview program does it but I couldn't

by the way, I am using labview 7.1 (full version) on windows 2000. PCI card is PCI-DIO-32HS, I installed the latest version of NI-DAQ. The system lists the PCI card under Acquisition devices (but also recognizes it under unknown devices) I can see it in MAX and change I/O. The box I have has a feature so that I can write a 0 to stop sending data and 1 to start sending so as to capture the beginning of data. I can write and I see the error LED gonig off and back on (in debug mode). I also know the setup of equipment is right because I have a test program in C that works fine under DOS.
Please, any help would be greatly appreciated, Thank you
