New quadrature encoder PC data acquisition cards from ComputerBoards allow encoder signals to be ported into PC applications without the need for add-on hardware – encoder support is built into the boards.
Available from Adept Scientific, the cards offer 2 or 4 channels, single ended or differential. They have 24-bit pre-settable hardware counters, so they can cope with very large counts. And they can handle a 1.25MHz input pulse rate if required. They also support an index pin, so count datums can be used.
