Hello;
In case you didn't see that particular device listed on Comedi site you will need to do a register level application to communicate with the board. Old versions of NI-DAQ doesn't support that in Linux either.
You can find good information about RLP at www.ni.com. To get all links to documentation about RLP, just type +register +level in the search field.
Hope this helps.
