Format of the parallel port base address

[bleaklow]

Just wondering if someone could please help with what I'm sure is a simple question

I'm currently trying the control the first 3 bits of the parallel port using the Out Port sub vi.

Using the Labview examples and help I can see how to find the base address of the port. My LPT1 port is 378 like most.

However the parallel port I'm trying to control is a added in extra PCI card and looking in the Device Manager this is LPT3 with 2 an address ranges starting at CF00 and CE00 . I understand how the address range of starting at 0378 becomes 378 for the base address. But whatabout CF00 asnd 2 ranges? What do I need to put as the base address for the Out Port for CF00?

thanks in advance

Well, if you have a base address of CE00, then you put a base address of CE00. Your numeric control/constant Display Format would obviously have to be set to hex display to do this. Otherwise, convert CE00 to decimal and enter that.
