Hi DMerchen, The equipment you have is not the right choice for doing encoder measurements. The reasons are: 1. The 6503 is a static digital I/O board. That means that you have to set or read values always through SW calls. I don't know how fast your encoder rotates, but it could be too fast for this board. Further the digital chip on the 6503 board has no up/down pin (for the direction),so it cannot support quadrature encoders without additional hardware. 2. The BNC-2090 is not a connector Block for the 6503. The BNC-2090 is made for E-Series boards.
What are your options? You need a board with counters. The best option for encoder measurements is a PCI-660x board. The second option is to use an E-Series board. There are different examples in LV and on www.ni.com which shows how to work with encoders.
