APPENDIX A : ISOLATED DIO GUIDE
A.2 Function Description
The IVH-7000 offers a 16-bit DIO (8-DI/ 8-DO) 20-pin terminal block connector.
Each bit of DI and DO equipped with a photo-coupler for isolated protection.
All IO pins are fixed by Hardware design and cannot change in/out direction in
runtime process. The definition is listed as follows:
