OVERVIEW

This board buffers signals coming out of the parallel port and into the breakout board. This prevents problems caused by new parallel ports that deliver low amperage signals because include a device that supports the IEEE 1284 standard

 FEATURES

• Supports IEEE 1284 Standard. This board supports IEEE 1284 Level 1 standards for bidirectional parallel communications between personal computers and peripherals.

• Bidirectional pins: 2-9.

• Output pins: 1, 14, 16 and 17.

• Input pins 10, 11, 12, 13 and 15.

• Buffered outputs. Outputs are buffered, allowing the card to output the signals without using the power from the parallel port. It can take the +3.3 or +5vdc signals from the parallel port and deliver solid +5vdc at 24 milliamps.

• Easy upgrade for existing setups. Upgrade the system just by plugging in the board and not touching the rest of the wiring.

• All TTL +5VDC or +3.3VDC Signals. Works with newer computers and laptops that have low voltage parallel ports.

• Internal enable fro outputs. An internal circuit detects when the board is connected to de parallel port to prevent undesired high state output pins. If the board is all outputs are disable.

• DB25 Male output connector. This connector allow this board be directly connected to the breakout board
