NI PXIe-6612 Quadrature Encoder Setup

[A.Elias]

I plan to use a NI PXIe-6612 and count up to 8 linear quadrature encoder sensors.  

I've determined that quadratures use the Gate, Source and Aux counter I/O.  I would like to know if I can se the Out counter I/O as a static digitial input/output with using the same counter for quadrature encoder sensing.  

Here is an example.  

I connect my quadrature encoder to Counter 1 Gate, Source and Aux connections.  Can I use Counter 1 Out connection as a statis digital I/O?

I plan to use P0.0 to P0.7 as digital outputs and need to use the counter OUT connections for digital inputs.  

Thanks,

ADam

Hi Adam,

Yes, this is doable. The gate, source, aux, and out terminals of the 6612's counters are all PFI lines, which can be configured as static digital I/Os. For more info, refer to page 4-3 of the user manual: http://www.ni.com/pdf/manuals/374008b.pdf
