REL-32 User Manual

Introduction

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.

REL-32 User Manual

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 Binary Switch Settings

1 2 3 4 5 6

280-283 000010 Off On Off On On On

288-28A 100010 Off On Off On Off On

2A0-2A3 010100 Off On Off Off Off On

328-32B 100101 Off Off On On On On

330-333 100110 Off Off On On Off On

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.

Address Selection Table

DIP-Switch Illustration

Note: Setting the switch ‘On’ or ‘Closed’ corresponds to a ‘0’ in the address, while leaving it ‘Off’ or ‘Open’ corresponds to a ‘1’.

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 33-

36.

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.

Software Installation

Windows 98/ME/NT/2000/XP Installation

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

1. Start Windows.

2. Insert the Sealevel Systems CD in to your CD drive.

3. If ‘Auto-Start’ is enabled for this drive the software will automatically launch. Otherwise, point your browser to the ‘Index.htm’ on the root directory of the CD

4. Select ‘Install Software’.

5. Select the Part Number for your adapter from the listing.

6. Select ‘Windows 98/ME/NT/2000/XP’. The setup file will automatically detect the operating environment and install the proper components. Next (depending on your browser) select the ‘Run this program from its current location’ or ‘Open’ option. Follow the information presented on the screens that follow.

7. 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.

8. 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.

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.
