This card provides an easy way of interfacing your
router based spindle with your steeper motor driver board. This
board includes a speed controller for routers. Additionally
provides terminals for inputs to be used as are required by the

IEEE 1284 Standard
circuitry recommended by the IEEE 1284 Level 1 standards for
bidirectional parallel communications between personal computers
DB25 connector for connecting a stepper motor driver
Pins 2-9 are sent to
the output port for connecting a driver board. Some driver boards
that can be used are G540, Xylotex, HobbyCNC, Rockcliff.
microcontroller based system allows the implementation of complex
algorithms for monitoring the system. It also allows the
possibility of having firmware upgrades without having to change
the board and rewire your system.

allowing the card to output the signals without using the power
from the parallel port. It can take the +3.3 or +5vdc signal from
the parallel port and deliver solid +5vdc at 24
External Enable Input
External Enable Terminal allows hardware disable of outputs. This
terminal can be connected in parallel with e-stop for hardware

Since the C33 takes care of conditioning (buffering) the signals, a
basic breakout board would do the job.
