Introduction

Overview

The REL-16.PCI provides 16 reed relay outputs. The outputs offer 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 is PCI bus specification 2.1 compliant.

The REL-16.PCI is designed to be used with a variety of Operating Systems including Windows

98/NT/ME/2000/XP, Linux, and DOS. The SeaI/O API (Application Programmer Interface) software

provides a variety of useful high-level function calls implemented as a Windows dynamic link library (DLL)

and as a Linux kernel module and library. In addition to the API, SeaI/O includes sample code and utilities

to simplify software development.

Before You Get Started

What’s Included

The REL-16.PCI is shipped with the following items. If any of these items are missing or damaged, please

contact Sealevel for replacement.

•REL-16.PCI Adapter

Advisory Conventions

Warning

The highest level of importance used to stress a condition where damage could result to the

product, or the user could suffer serious injury.

Important

The middle level of importance used to highlight information that might not seem obvious or a

situation that could cause the product to fail.

Note

The lowest level of importance used to provide background information, additional tips, or other

non-critical facts that will not affect the use of the product.

Optional Items

Depending upon your application, you are likely to find one or more of the following items useful for

interfacing the REL-16.PCI to real-world signals. All items can be purchased from our website

(http://www.sealevel.com) or by calling (864) 843-4343.

•DB-37 Male to DB-37 Female 6’ Cable - (Part Number CA112)

This cable extends the DB-37 connector on the REL-16.PCI to six feet and is pinned one-

to-one.

•DB-37 Male/Female Terminal Block (Part Number TB02-KT)

Break out serial and digital connectors to 37 screw terminals for easy field connection.

The TB02 terminal block is designed with both DB-37 male and female connectors,

therefore; it can be used with any DB-37 board regardless of the board's port gender.

•Cable and Terminal Block Kit (Part Number KT101)

For convenient and easier ordering, the KT101 includes the TB02-KT terminal block and

CA112 cable in a single kit.

Installation

Operating System Installation

For Windows Users

Begin by locating, selecting, and installing the correct software - SeaIO Software.

SeaIO Software can also be downloaded from the 8003-product page: REL-16.PCI Product Page

Other Operating Systems

Refer to the appropriate section of the Serial Utilities Software.

Windows NT Card Installation: After accomplishing the above steps, bring up the Control Panel and

double-click on the SeaI/O Devices icon. To install a new card, click "Add Port". Repeat this

procedure for as many SeaI/O cards as you wish to install.

LINUX INSTALLATION

Refer to Linux Archives - Sealevel. This link contains valuable information on installing your serial

adapter in the various Linux releases. Also included is a series of files explaining proper Linux syntax and

typical Linux serial implementations.

For additional software support, please call Sealevel Systems’ Technical Support, (864) 843-4343. Our

technical support is free and available from 8:00AM-5PM Eastern Time, Monday through Friday. For

email support contact: mailto:sup[email protected].

INSTALLATION, CONTINUED

Hardware Installation

The adapter can be installed in any 5V PCI expansion slot.

Do not install the Adapter in the machine until the software has been fully installed.

1. Turn off PC power. Disconnect the power cord.

2. Remove the PC case cover.

3. Locate an available 5V PCI slot and remove the blank metal slot cover.

4. Gently insert the PCI adapter into the slot. Make sure that the adapter is seated

properly.

5. After the adapter has been installed, the cables should be routed thru the opening in

the bracket. This bracket also features a strain relief function that should be used to

prevent un-expected cable removal.

6. Replace the screw you removed for the blank and use it to secure the adapter into the

slot. (This is required to ensure FCC Part 15 compliance.)

7. Replace the cover.

8. Connect the power cord

Installation is finished.

Programming the REL-16.PCI

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. The software also includes 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 REL-

16.PCI. 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.

Programming for Linux

SeaI/O for Linux consists of two major parts: a kernel module and a library. The

kernel module is a simple IO pass-through device, allowing the library to handle the

more sophisticated functions provided to SeaI/O users. It is provided in a ‘tarball’

format and can easily be compiled and included in the kernel build.

Digital I/O Interface

The REL-16.PCI provides two parallel reed relay output ports. The ports are

organized as ports A, B, C, and D. In order to maintain compatibility with the

existing ISA interface adapter (Sealevel Item# 3095), ports C and D (Base

address+2 and 3) are the reed relay output port addresses.

Output Ports (Reed Relay)

Reed relays provide very high quality, long life, low current (10 Watt maximum), dry

contact switch closures. Reed relays are not suited for high current applications,

and can be destroyed by inductive load switching, where a spark occurs across the

contacts internally. The relays are normally open, and close when energized.

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.

Writing the Outputs

The output ports are the only ports that can be written. The relays on a standard REL-16.PCI are normally

open. To close a relay a one must be written to the appropriate bit.
