104-DIO-48S &

104-DIO-24S

48 or 24 Lines of

PC/104 DIGITAL I/O WITH COS

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

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.

The 104-DIO-48S board uses two

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.

S O F T WA R E

The 104-DIO-48S is supported for use

in most operating systems and includes a

free DOS, Linux and Windows 95/98/Me/

NT/2000/XP/2003 compatible software

package. This includes sample programs

and source code in "C" and Pascal for DOS,

and Visual Basic, Delphi, C++ Builder, and

Visual C++ for Windows. Also included is

a graphical setup program in Windows.

Embedded OS support includes Windows

XPe and CE. Linux support includes

installation files and basic samples for

programming from any user level via an

open source kernel driver.
