How do I using NI-9403 for quadrature decoder circuit?

Hi, all
Using 74HCT193, I get the required number of bits and reset on the z input, from some limit switches or from a digital output from the NI 9403, where the parallel lines from the counter go into digital inputs on the 9403. Is it possible to connect them to make a quadrature decoder circuit?

Anyone have ideas of it? I’m fairly new in all of this, so if possible a simple explanation would be nice. Thank u🙂

The chassis you'll need to house the 9403 will have its own 32-bit counters and the ability to perform the quadrature decode for you.  You shouldn't need an external counter circuit or quad decode circuit.

 

Here's a general guide for getting started.

CAUTION! New LabVIEW adopters -- it's too late for me, but you *can* save yourself. The new subscription policy for LabVIEW puts NI's hand in your wallet for the rest of your working life. Are you sure you're *that* dedicated to LabVIEW? (Summary of my reasons in this post, part of a voluminous thread of mostly complaints starting here).
