PC-DIO-24PNP Driver for 98

[OhioKenBob]

Updating Test/Monitoring System, software written in Quick-Basic 4.2 running under DOS. The DOS system had a PC-DIO-24 (not PnP) card. Trying to run same software on Windows-98 system, keep getting prompted to install driver for PC-DIO-24PnP card. Can't find a stand alone driver for this card.

Do I have to download NI-DAQ in order to get a driver ?

Does it need a driver if the program is sending and receiving from an address ?

Hi OhioKenBob-

The driver for your card with Visual Studio, C++, or LabVIEW and Windows 98 is Traditional NI-DAQ 7.1.  You will need this driver for new application development.

If your older Q-Basic program writes and reads directly from memory addresses (commonly known as Register Level Programming) then no driver will be needed; your software must control all communications by writing directly to the DIO board's registers.

Hopefully this helps-

Thanks, I will give it a try.

Working without a driver does work. The one problem is setting the address of the card. There are no dip switches so you have to either use the default (if you can find what it is, I couldn't) or guess. Finally downloaded NI-DAQ set the address on the card, and the direct addressing worked fine.

Hi OhioKenBob-

I apologize for the confusion- because you mentioned you were using RLP I assumed you already knew the base address of the card.  Regardless, I'm glad to hear you're up and running now.

Thanks-
