USBexpansion card / encoder

Hi i can use some help. I have connected 2 encoders to the USBexpansion card
A/D 1 and A/D 2

"[ A/D used by Iocard Master expansion USB ]
USB_AD=2"

What i would like to know is how to call them?

"Var 4 Link IOCARD_ENCODER Input 0 Aceleration 1 Type 2"

because i saw ( in doc Install + user's manual) that type 2 means connected the mastercard?
and aceleration 1,2,6 how does that work?
regards,
Henri

I think I got it .
thanks any way.
Henri
