I am running a PXI rack with an NI PXI6225 IO card. I'm trying to use the digital output ports but they seem to default to TTL (+5V) logic. It appears from the manual i should be able to change this to 3.3V logic but i cant work out how do it. Using Labview 2011 sp1 if relavant.
Thanks for any help offered!

That card only outputs TTL level. I think it can read LVTTL though. If you really need LVTTL, then use a voltage changeover buffer. Look on digikey for a octal buffer than can change the voltage levels.

Hi,
Thanks for your reply, my first posting experience on NI has been a successful one!
At the moment have gone old school and used a voltage divider/resistor pair but will be look at your suggestions for something a bit more permanant.
