Hey there,

What document are you using to get the pinouts of your R-Series card? Can you link us to it? Can you take a screenshot of your host VI too?

Thanks,

i am using the quick reference label of scb-68 to get my pinouts of my card..additionally i don't use host vi for that measurement (is that wrong??) .thank you for replying

Ok - I see you are using the reference label. Are you using the R-Series Quick Reference Label? http://www.ni.com/pdf/manuals/320745b.pdf Page 8 of Appendix B.

Thanks,
