Introduction

The DIO-16.LPCIe provides 8 optically isolated inputs and 8 reed relay SPST (single pole-single throw)

outputs. The inputs protect the PC and other sensitive equipment from spikes and ground loop current that

can be generated in industrial environments, while the outputs provide high quality, long life, low current

(10 Watt maximum), dry contact switch closures. Reed relays are well suited for low current applications.

The relays are normally open and will close when energized.

The board meets the requirements a low profile PCI Express add-in card as defined by the PCI-SIG in the

PCI Express Card Electromechanical Specification Revision 1.1.

The DIO-16.LPCIe is designed to be used with Windows Operating Systems. The SeaI/O API (Application

Programming Interface) included in Sealevel’s software provides a variety of useful high-level function calls

implemented as a Windows dynamic link library (.DLL). In addition to the API, SeaI/O includes a device

driver, sample code, and utilities to simplify software development.

Features

•PCI Express x1 compliant

•Eight optically isolated inputs

•Eight Reed relay outputs (SPST)

•Low Profile compliant

Software Installation

Windows Installation

Do not connect the hardware until the software has been fully installed.

Only users running Windows 7 or newer should utilize these instructions for accessing and

installing the appropriate driver via Sealevel’s website. If you are utilizing an operating system

prior to Windows 7, please contact Sealevel by calling 864.843.4343 or emailing

[email protected] to receive access to the proper driver download and installation

instructions.

1. Begin by locating, selecting, and installing the correct software from the Sealevel software

driver database.

2. Type in or select the part number (#8012e) for the adapter from the listing.

3. Select “Download Now” for SeaI/O for Windows.

4. The setup files will automatically detect the operating environment and install the proper

Programming the DIO-16.LPCIe

Sealevel’s SeaI/O software is provided to assist in the development of reliable applications for the Sealevel

Systems family of digital I/O adapters. Included on the SeaI/O CD 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 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 DIO-16.LPCIe. 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 with SeaI/O.

Further documentation on these samples can be found by selecting “Start/Programs/SeaIO/Sample

Application Description”. Information about where the files are physically stored on your disk is also

included in this same file.

Reference the following sections for more information about the meaning and use of the registers available.

Address Mode Mode D7 D6 D5 D4 D3 D2 D1 D0

Base+0 Input Port A RD PAD7 PAD6 PAD5 PAD4 PAD3 PAD2 PAD1 PAD0

Base+2 Output Port C RD/WR PCD7 PCD6 PCD5 PCD4 PCD3 PCD2 PCD1 PCD0

Reading the Inputs

The inputs are active Low. If no voltage is applied across one of the differential inputs, it returns a one on

that bit. If an AC or DC voltage is applied, it returns a zero on that bit.

Reading the Outputs

The relay ports return the ones complement of the value that is currently being used to drive the relays.

When using the API the actual value is returned not the complement of the value.
