The 7I42 only has single ended inputs so you can either use the 7I42 and only connect the A,B,X signals (this would mean you would not gain the noise immunity of the differential encoder outputs), or you could use a differential interface card like the 7I47. Since you already have a 7I42, I guess you might as well try it and only upgrade to a 7I47 if noise on the encoders is a problem. > ------------------------------------------------------------------------------ > > Download Intel® Parallel Studio Eval Try the new software tools for > yourself.
