I also have written some code for the National Instruments Lab PC+, Industrial Computer Source Multiplexing AIO cards, National Instruments DIO-96 & 24, And some solid state relay DIO cards from Industrial Computer Source (Which by the way Industrial Computer Source is way less expensive that national instruments at the sacrifice of some slo blow fuses in some cases, or special connectors needing to be soldered in). Some faulty interface cards built by guy who really sucks were repeatedly blowing out channels on my dio boards from Industrial Computer Source and they repaired them twice without charging me.
