Introduction

Overview

The REL-32 provides 32 reed relays that can switch power, data, or other electronic signals for control

applications. 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 REL-32 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) included on CD

with the REL-32 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.

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-32 to real-world signals. All items can be purchased from our website

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

DB-37 Male to DB-37 Female 6’Extension Cable (Item# CA112)

The CA112 is a cable that extends the DB-37 connector

on the CA172 cable an additional six feet and is pinned

one-to-one.

DB-37 Male/Female Terminal Block (Item# 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 (Item# KT101)

For convenient and easier ordering, the KT101

includes the TB02-KT terminal block and CA112

cable in a single kit.

Card Setup

The REL-32 contains several jumper straps for each port that must be set for proper operation.

Address Selection

The REL-32 occupies 4 consecutive I/O locations. The DIP-switch (SW1) is used to set the base address

for these locations. Be careful when selecting the base address as some selections conflict with existing

PC ports. The following table shows several examples that usually do not cause a conflict.

Address Selection Table

The following illustration shows the correlation between the DIP-switch setting and the address bits used

to determine the base address. In the example below, address 300 is selected as the base address. Address

300 in binary is XXX 100000 XXX where X = a non-selectable address bit and address bit A9 is always a 1.

DIP - Switch Illustration

Setting the switch ‘On’ or ‘Closed’ corresponds to a ‘0’ in the address, while leaving it ‘Off’ or ‘Open’

corresponds to a ‘1’.

IRQ Header E2

Header JP1 provides a means of connecting +5 VDC and +12 VDC from the PC bus to the Options

Header. The center pin of this header is connected to P3 pins 3336.

Optional Cable Connector P4

Discrete access to both sides of all relays is provided by attaching the optional cable (CA-108) to pin header

P4 with the colored edge of the ribbon cable attached to pin one. Removing all the jumpers connecting row

P1 to P2 places the A-side of each relay at the on-board DB-37 and the B-side at the optional cable’s DB-37.

Installation

Software Installation

Windows 98/ME/NT/2000/XP Installation

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

For Windows Users

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

database.

2. Select the Part Number (3098) for your device from the listing.

3. Click the ‘Download Now’ button. The SeaIO software is available for Windows and Linux.

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

components.

5. A screen may appear with the declaration: “The publisher cannot be determined due to the

problems below: Authenticode signature not found.” Please select the ‘Yes’ button and proceed

with the installation. This declaration simply means that the Operating System is not aware of the

driver being loaded. It will not cause any harm to your system.

6. During setup the user may specify installation directories and other preferred configurations. This

program also adds entries to the system registry that are necessary for specifying the operating

parameters for each driver. An uninstall option is also included to remove all registry/INI file entries

from the system.

To confirm that the SeaIO driver has been successfully installed, click on the ‘Start’ button, and then

select ‘All Programs’. You should see the ‘SeaIO’ program folder listed.

You are now ready to proceed with connecting the 3098 to your system. Refer to the Hardware

Installation section for details.

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

and double-click on the SeaIO Devices icon. To install a new card, click “Add Port”. Repeat this

procedure for as many SeaIO cards as you wish to install.
