SEALEVEL 75837 1 REL 16 PCI Systems DIO 16 PCI Digital I O
Card

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.

Installation

Operating System Installation
For Windows Users

Begin by locating, selecting, and installing the correct software – SeaIO Software.
SEO Software can also be downloaded from the 8003-product page: REL-16.PCI Product Page

Other Operating Systems
Refer to the appropriate section of Serial Utility 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, at 864-843-4343. Our technical support is free and available from 8:00 AM-5 PM Eastern Time, Monday through Friday. For email support contact: mailto: support@sealevel.com.

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.

Turn off PC power. Disconnect the power cord.
Remove the PC case cover.
Locate an available 5V PCI slot and remove the blank metal slot cover.
Gently insert the PCI adapter into the slot. Make sure that the adapter is seated properly.
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 unexpected cable removal.
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.)
Replace the cover.
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 the 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 REL16.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) is 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), and 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.

Direct Hardware Control
In systems where the user’s program has direct access to the hardware (i.e., DOS) the table below gives the mapping and functions that the REL-16.PCI provides.

Function Available

| Port| Port Address|

---|---|---|---
| A| Base + 0| Unused
| B| Base + 1| Unused
R/W| C| Base + 2| Output Port
R/W| D| Base + 3| Output Port
| | |

R/W = Read or Write

Reading the Outputs
The relay ports return the ones that complement 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 are on a standard REL-16.PCI is normally open. To close a relay one must be written to the appropriate bit.
