G4 C programming on PCI-6503

[Markie147]

I have a new G4 (AGP) PowerMac and a problem:

Part 1: using NI-DAQ 4.9.4 I want to use a new G4 to control a PCI-1200 and a PCI-6503. The latter is not recognised by the NI-DAQ control panel. What is the version of the interface libs I should be using in this case ?

Part 2: If I install the 6.6.x configuration utility I can use the utilty to control both my PCI-boards (i.e. they both work using it and get Device Numbers assigned) but in My C programming environment I cannot access them reliably (and not the PCI-6503 at all). Again what are the relevant (up-to-date) interface libraries I should be using with this utility?

Perhaps there is something else I have not thought of but it seems I should be using 6.6.x and therefore n
eed more reliable/usable C interfaces. At the moment I am using the NI-DAQ.xcoff interface (dated 1996 but supplied with the boards)

Thanks for any help you can offer

Hello;

The problem there is happening because NI-DAQ version 4.9.4 doesn't support the PCI-6503 board. So, to use that board with Mac OS, you need to have the 6.6.x version. But, then, that last version only supports Labview, that explains why you are having those problems with the C interface.
Unfortunately, you will need to make a choice on what Programming Language you want to use, then choose the NI-DAQ version appropriate for that Language and board.
If you choose Labview, you can work with both cards at the same machine and install NI-DAQ 6.6.
Hope this helps.
