https://ni.lithium.com/t5/LabVIEW/Migrating-to-PCIDIO-24/m-p/827#M596 I'm currently using an inexpensive ISA Digital I/O card and need to migrate<BR />to a PCIDIO-24. <BR /><BR />1.) The current software contains Activex controls that talk to the board<BR />which can't be modified, although the LabView code calling them can be modified.<BR /> The control is expecting a properly configured 8255 port at I/O address<BR />0x025E (0x0240 + 0x1E). Is there any way to configure the PCIDIO-24 through<BR />LabView so it's Port C lands at this address?<BR /><BR />2.) Port C of the 8255 chip on the old board is split, using the upper 4<BR />bits as inputs, the lower 4 bits as outputs. Is there any way to configure<BR />the PCIDIO-24 to do this through LabView?<BR /><BR />Thanks,<BR /><BR />Doug Gordon <BR /> Thu, 30 Mar 2000 01:21:28 GMT Doug 2000-03-30T01:21:28Z https://ni.lithium.com/t5/LabVIEW/Migrating-to-PCIDIO-24/m-p/827#M596 I'm currently using an inexpensive ISA Digital I/O card and need to migrate<BR />to a PCIDIO-24. <BR /><BR />1.)
