I'm
not aware of any DMX-512 interfaces that come with a LabVIEW API.
However, most of those interfaces come as PCI cards or as
serial-to-DMX512 converters.
In the first case, there is always a
DLL to communicate with the PCI card and you can use LabVIEW's Call
Library Node to call that DLL from your LabVIEW code.
Quite a few
DMX-512 converters are connected through RS232 (or RS485) and LabVIEW
as built-in support for the serial port. This seems to be the easiest
approach. Here is a link to a Discussion forum which discusses this:
