This is a basic breakout board. It
provides screw-on terminals to pins 1-17 and
ground of the parallel port. It comes with a females DB25
connector. Pins 18-25 are connected ground.
This card does not provide
any kind of signal conditioning. It does not have buffers,
optoisolators, capacitors (for absorbing noise), or pull-down
resistors. It is for use with devices that do not need signal
condition, such as other cnc4pc boards.
Do not use this board for
wiring Geckodrvies, these drives require 16 milliamps signals, the
parallel port can only deliver 10 milliamps. Using this board for
these drives can cause lose of steps and unreliable
