DASYLab NI-CAN Card problems

[Dasylab User]

Has anyone any experience of using the NI-CAN 2 PCI card with Dasylab?
Am capturing data at 100Hz (block size 50) & saving to disk in Famos format. PC is a HP Compaq 3.2Ghz P4.
Have noticed the data becomes increasingly distorted the longer the worksheet runs. It appears to freeze (flat-line) at the start of each block & the period it freezes is a function of how long the worksheet has been running. In the extreme (i.e. after many hours of running), the data remains fixed for the entire duration of each block.
The problem appears hardware specific. Have tried the same worksheet on a slower 3.0Ghz P4 & it doesn’t exhibit the problem. Turning multi-threading/hyper-threading on/off makes no difference.
DasyTec seem reluctant to discuss & I need assistance fast!
Thanks,
Paul Towle.

After long time tests this effect could be reproduced and will be fixed in a later DASYLab release version.
