DMX-512 driver/code

[Amaturi]

I would like to build a program to control DMX-512 systems.
Is there any experience with this protocol in LabVIEW?
Are there any drivers or VIs available somewhere?
Thanks in advance.

Hi Jan,

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 LabVIEWs 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.

Good luck!

I agree with Einstein,

Easiest way would be to connect to the built-in Serial port on the cRIO to connect to a rs232/dmx512 converter, and then simply use VISA commands to communicate.

I am no pro on the DMX512 protocol, but I suppose it is possible to create your own custom drivers through the FPGA interface, but you would really have to know what you are doing.
