FUNCTIONAL BLOCK DIAGRAMS

Inputs 10, 11, 12 13 and 15 (Port 1 and Port 2) Schematic

Note: The Smooth Stepper includes an Schmitt Trigger in those input pins.
3.2

Inputs 2-9 (Port 2) Schematic

Using an RC Low Pass filter followed by a Schmitt Trigger gate will reduce the effect of
the noise from driver or other devices. This eliminates the high frequency components of
the noise and generating a fast changing signal.
Outputs 1, 14, 16 and 17 (Port 1 and 2) and outputs 2-9 (port 1).
All those pins are directly wired to the C25 output terminals.
