GiBiDi gate controller

I was wondering if anyone on this board has had experience with a GiBiDi F4 Plus gate controller. I have one and have interfaced it to Indigo using a EasyDAQ card and I can now operate the gate using Indigo. However, I would also like to be able to sense the positions of the gate (open, closed, opening, closing, stopped partially open) in Indigo.

Based on a quick study of the I/O connector I think I can get some information by using relays to operate EasyDAQ inputs, But, before I proceed, I though it best to see if someone else has already worked any of this out.
