SeaLINK PIO-48 User Manual

Introduction

The SeaLINK PIO-48, part number 8203, provides an easy method for interfacing

common digital I/O circuitry via any computer’s USB port. Typical applications

include control/monitoring of TTL devices (e.g. LEDs, small solenoids, small

relays) and interfacing to solid-state relay racks (SSRs) for high-power AC or DC

loads.

The SeaLINK PIO-48’s 48 digital I/O channels are accessed via two 50-pin header

connectors with industry-standard pin out. Each header provides 24 bits of digital

I/O divided into three eight-bit groups. Each eight-bit group may be individually

configured via software command as input or output to best match your particular

application requirements.

The SeaLINK PIO-48 is designed to be used under Windows 98/ME/2000/XP. The

SeaI/O API (Application Programmer Interface) included on CD with the SeaLINK

PIO-48 provides a variety of useful high-level function calls implemented in a

Windows dynamic link library (DLL). This API gives access to the SeaLINK PIO-

48’s I/O from Windows-based platforms such as Visual C++. In addition to the

API, SeaI/O includes an ActiveX control along with sample code and utilities to

simplify software development.
