This board, compact in design, allows for the reading of a line-driver 5V encoder. Thanks to its built-in voltage regulator the power supply is stable even in systems comprising a high number of axes. The interpolation is set at 4x, te maximum attainable from a square wave encoder. This way, for example, a 3600 pulse per rotation encoder can reach a final resolution of 14400 pulses per rotation.

A "latch" digital input allows the board to "freeze" the value of the encoder, value that is then saved in a dedicated memory cell while the board keeps counting the pulses. This functionality, and the corresponding software commands for reading the memory, are indispensable when using these boards on a measurement machine. The position of all of the encoders are read simultaneously with a maximum temporal error of less than a microsecond. The board features a digital input for auxiliary buttons, an output for a status LED and a circuit for running diagnostics on all of the encoder's signals. Using this circuit, all of the signals can be checked, thus finding possible malfunctions of the encoder or, more simply, disconnected wires.
