» Functional Description
This board is a 3-axis quadrature encoder interface board for the IBM PC/AT bus compatibles.
For each encoder, phase 0, phase 90 and index pulse inputs are provided.
Inputs may be single ended (A, B, C) or differential (A+, A-, B+, B-, C+, C-).
Inputs are conditioned by a four-stage digital filters.
The maximum input rate in quadrature decode mode is 1MHz.
The conditioned inputs are applied to the 16-bit counters.
The counter may be used for quadrature decoding, pulse and direction-input counting, or as a pulse input up/down counter General Specifications
