Remap PCI-DIO-96 register space

[CharlieD]

WindowsXP SP3, Labview 7.1, NI-DAQ 7.4.4, (2) PCI-DIO-96 cards

I have an app that requires direct access the 82C55 registers on the cards.  Previously used the ISA version of the cards which mapped the registers (via switches/jumpers on the board) into low address space (0x180 & 0x2A0).  The new PCI cards are mapped by the OS into D000 & F000.  I do not seem to be able to access the registers at these base addresses.  From reading some of the posts on various forums, it sounds like I need to remap the registers into low address space by writing a new base address into one of the MITE ASIC registers.  Is this correct, and if so, is there a way to do this from inside LabView using the TDAQ/LabView VIs?

TIA

Charlie,

Thank you for visiting the discussion forums. It definitly sound like you are on the right track.  You should be able to use that .dll in LabVIEW to call all of those function.  Here is an article on how to do that.  I hope this helps in your application.
