This card provides an easy way of interfacing your inputs and outputs from the parallel port. It provides terminals and RJ45 for connections. It conditions the signals for use in CNC applications.

Buffered inputs and outputs.

Outputs are buffered through integrated circuits, allowing the card to output the signals without using the power from the parallel port. It can take the +3.3 or +5vdc at less than 1 milliamp from the parallel port and deliver solid +5vdc at 24 milliamps.

IEEE 1284 Standard compatible.

Includes the circuitry recommended by the IEEE 1284 Level 1 standards for bidirectional parallel communications between personal computers and peripherals.

RJ45 connectors for all I/Os.

You only have to use standard networks cable to make all your connections.

Microcontroller based SCHP.

This board comes with a microcontroller that allows the implementation of a complex algorithm for sampling and analyzing the SCHP signal.

Output pins 1,2,3,4,5,6,7,8,9,14,16,17.

Input pins 10,11,12,13,15.

Input and output pins with close by ground or +5vdc connections.

The common terminal to pins 2-9 can be ground or +5vdc.

In the RJ45 terminal, there are wires with GND or +5vdc to allow using drivers that require +5vdc or GND as a common.

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 disable the system manually, or you can install an external Safety Charge Pump or other external device.

All TTL +5VDC or +3.3VDC Signals.

Works with newer computers and laptops that have low voltage parallel ports
