Hello,
i'm using some VXI Racks for data acquisition with the signalCalc software from dataphysics.
The VXI rack is connected to a computer by an MXI-2 wire (with an MXI-2/PCI Card). The VXI Rack is composed of an MXI-2 card, several acquisition card and one SCSI hard drive.
During acquisition, i made the recording on the VXI SCSI HD. So i have to repatriate data from the VXI HD to the computer at the end of the acquisition.
My problem is that the transfert rate is around 0.500 Mb/s. That is strange is if i click continously with the computer mouse, the transfert rate raise. If i stop clicking, it decrease...
Do someone know how it is possible and how can i correct this matter?
I'm running windows XP sp2 with the 3.3 NI driver.
ps : On windows 2K computer the transfert rate is arround 1Mb/s.
Thanks and regards from france.
Cyrille
