I'm unable to find the driver for a National Instruments PCI Rs232/485 isolated board , should be model PCI-8433/4.
MAX do not find the board.
Labview version 8.2.1 , Windows 7 32 bits, NI-DAQmx 9.1.

It is probably newer than what you are looking for, but I would give NI-Serial 3.9 a try. You really just need the ports to show up as COM ports and then VISA handles the rest.

Thanks for the suggestion.
In fact I really do not understand why NI do not leave as available old version of drivers.
There are a lot of reasons for keep using old Labview versions that need old drivers.
NI-serial 3.9 generates an error during install, asking to remove some Labview 8.2.1 component , I could achieve it only using Windows "regedit" to clean the registry .
Encouraged by the success , I was able to install NI-serial 3.9 with Labview 6 , installing first NI-serial 3.9 and then Labview 6 , with the options for VISA , drivers, and other stuff that might conflict with NI-serial 3.9 , disabled.
Trying to install NI-serial 3.9 after Labview install leads to a error message about VISA old version , that "regedit" could not solve.
I will test both Labview 8.2.1 and Labview 6 with NI PCI-8433/4 , PCI-6503 , USB-485 /4, USB-6501
