1.0 OVERVIEW
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 user.
2.0 FEATURES

IEEE 1284 Standard compatible. Includes the circuitry recommended by the
IEEE 1284 Level 1 standards for bidirectional parallel communications between
personal computers and peripherals.

DB25 connector to connect the stepper motor driver board. These
connectors manage only pins 2 – 9.

Microcontroller based SCHP. This board comes with a microcontroller that
allows the implementation of a complex algorithm for sampling and analyzing the
SCHP signal.

Terminals to control the router speed.

Additional Terminals for controlling a coolant pump or vacuum.

Speed Control Signal Can Be PWM or 0-25HZ Pulse Stream.

Works with 110 or 220VAC at 60 or 50 HZ.

For 2.5HP or 1800 Watt Routers.

LEDs Show The Operation Mode.

Buffered inputs and outputs. Outputs are buffered through the use of high
speed and high current buffers 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 milliamps.

Input and output pins with close by ground or +5vdc connections

External Enable Pin (EN). The board has a pin that allows you to enable/disable
all the outputs at once. The board requires +5vdc in the EN pin. If it is not
present, it will send all the outputs to ground. You can use this to enable or
