provide a total of 48 or 24 lines of digital

I/O with counter/timer for PC/104-based

data acquisition. This low-cost, high-

performance, reliable board features

Change of State (COS) detection on user-

selected ports, allowing the board to

generate an interrupt port by port. Since

one READ determines the data, there is no

need for constant polling, which greatly

reduces processor overhead and allows

applications to run more smoothly.

48 or 24 parallel lines of 82C55 digital I/O with tristate buffers

prevent unintended control of external equipment

IRQ on input change of state (COS) eliminates the need for

constant polling

High sink/source current 64mA/32mA

I/O pulled up to 5V for contact monitoring

Compatible with Opto-22 and other industry standard I/O racks

The 104-DIO-48S and 104-DIO-24S

82C55A chips to provide a computer

interface to the 48 I/O lines. Each chip

provides two 8-bit ports and two 4-bit ports

with software programmable direction.

Each I/O line is buffered and capable of

sourcing 32mA or sinking 64mA. Pull-ups

to 5V are provided for contact monitoring.

Optionally available is an 82C54 chip

that includes three 16-bit counter/timers

factory configured in an optimal module for

use as event counters, frequency output,

pulse width, and frequency measurement.

Connections are made via two industry-

standard 50-pin headers plus one ten-pin

header for the optional counter/timer.

The 104-DIO-48S board uses two
