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 PIO48’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.

items can be purchased from our website (http://www.sealevel.com
864-843-4343.
For TTL applications:
Terminal Block Kit - (Part Number KT107)
− Kit includes the TB07 screw terminal block and CA167 ribbon cable
for connecting one of the SeaLINK PIO-48’s 50-pin header
connectors to your I/O. 6” Snap track and DIN rail clips are included
for DIN rail mounting.
IDC 50 to IDC 50 Pin 40" Ribbon Cable (Part Number CA167)
− Interfaces each of the SeaLINK PIO-48’s 50-pin header connectors.
) or by calling
Simulation/debug module (Part Number TA01)
− Module allows monitoring status of output pins and controlling state
of input pins. An LED corresponding to each port bit illuminates to
indicate state. Eight position DIP-switches are used to generate input
status changes.
