have encountered a serious compatibility problem with National
Instruments (NI) data acquisition device PCI-6733. The observation is
related to a wide-ranging research at the Tampere University of
Technology, Department of Signal Processing. At the present, my
PCI-6733 works only with a single PC. For example, running the card
with a recently purchased HP Compaq dx2250 results in error messages
etc. Even the NI's Measurement & Automation Explorer software's
self-testing fails totally. Only old PC-hardware appears to work with
PCI-6733, and I'm running the damn device on a legacy PC with MSI845
Pro2 motherboard, 1700MHz Pentium4 processor and 1.5 GB 133 MHz SDRAM
For some reason, the NI's customer support provides no tips or possible solutions to this rather odd problem (although they admit that the compatibility problem exists, and at least one other user has reported the same problem). Recent software updates have not been helpful either. As the PCI-6733 is still quite an expensive piece of equipment, you could expect some immediate action, but so far NI's support has been negligible. Could anyone inform me, e.g., of other possible PC components that provide trouble-free performance?
Thanks in advance,
Thanks for your quick and detailed answer.
Overcoming newly purchased dx2250 sources of incompatibility interest me the most. To go to your questions, the north bridge of dx2250 appears to be ATI RS485 and south bridge ATI SB600 chipset. The motherboard is much likely MSI 0A7C (maybe also sold as model MS-7242) with ATI Radeon XPRESS 1150. If it helps, PCI is possibly on the base of Realtek RTL8100C controller, but power specifications of the PCI bus are unclear. Do you know if the 3.3V, 5V and 12V rails are missing with MSI 0A7C? Are there any known compatibility problems with the above chipsets? My PCI-6733's part number is 187992D-01.
Thanks also for recommending a Dell computer with the PCI-6733. After all the trouble I’ve seen, you learn to appreciate this sort of tips.
