SEALEVEL SeaLINK PIO-96 USB to 96 Channel TTL Digital Interface Adapter User Manual

SEALEVEL SeaLINK PIO-96 USB to 96 Channel TTL Digital Interface Adapter

Introduction

The SeaLINK PIO-96, part number 8205, 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-96’s 96 digital I/O channels are accessed via four 50-pin header connectors with industry-standard pinout. 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-96 is designed to be used under Windows 98/ME/2000/XP. The SeaI/O API (Application Programmer Interface) included in Sealevel’s software 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-96’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.

Digital I/O Interface

The SeaLINK PIO-96’s 96 digital I/O channels are accessed via two industry- standard 50-pin header connectors. Each header provides 24 bits of digital I/O divided into three eight-bit ports. Each port may be individually configured via software command as input or output.

50-pin Header Connector
You will need to open the SeaLINK PIO-96’s enclosure to access the four header connectors P2, P3, P4, and P5. To open, remove the four screws found on the bottom panel of the unit. Once cables are connected to the headers reassemble the enclosure with the cables exiting the opening on the back panel of the unit.
Each of the four 50-pin connectors has the following pinout which is compatible with a wide variety of solid-state relay racks:

Programming the SeaLINK PIO-96

Sealevel’s SeaI/O software is available to assist in the development of reliable applications for the Sealevel Systems family of digital I/O adapters. Included in Sealevel’s software and drivers are driver functions for use in accessing the I/O as well as helpful samples and utilities.

Programming for Windows
The SeaI/O API (Application Programmer Interface) provides a variety of useful high-level function calls implemented in a Windows dynamic link library (DLL). The API is defined in the help file (Start/Programs/SeaIO/SeaIO Help) under “Application Programmers Interface.” This help file also includes in the SeaIO software provides detailed information dealing with installation/removal of the software and information about latency, logic states, and device configuration. For C language programmers we recommend using the API to access the SeaLINK PIO-96. If you are programming in Visual Basic, using the ActiveX control included with SeaI/O is advised.

Samples and Utilities
A variety of sample programs and utilities (both executable and source code) are included in the software for the SeaI/O.
