Hi,
AlexS is absolute right: when you will used power supply from PC, you must used "rail-to-rail" OP AMP.
Unfortunately, A&A not support ILDA Standard (5 V) (or ILDA not support A&A

))
We have decided this problem in our new version of cards: we have installed in card four switches for 5 or 10 Volt for X, Y, Z and int/colors/shutter.
Result one from experiment:
Power supply PC was +11,3/-11,6 Volt (in other PC I have seen from 10,5 to 13 Volt

((
Max. out voltage: (must be 10 Volt):
If was used TL084: 8,3-8,6 Volt
If was used OP482: 9,3-9,6 Volt
If was used OP484: 9,9-10V Volt
But, unfortunately, cost of OP484 is very big (9-12 USD)
Alex's proposition is better...
