SEALEVEL SeaLINK REL-16 Digital Interface Adapter User Manual

SEALEVEL SeaLINK REL-16 Digital Interface Adapter

Introduction

The SeaLINK REL-16 provides 16 reed relays that can latch power, data, or other electronic signals for control applications. The adapter is USB 1.1 compliant. The SEALINK REL-16 is designed to be used under Windows 98/ME/2000/XP. The SeaI/O API (Application Programmer Interface included in the software provides a variety of useful high-level function calls implemented in a Windows dynamic link library (DLL). This API gives access to the SeaLINK REL-16 I/O from Windows-based platforms such as Visual C++. In addition to the API, SeaI/O includes an ActiveX control along with sample code and utilities to simplify software development.

Software Installation

Windows Installation

Do not connect the SeaLINK REL-16 Adapter to the host USB device 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 support@sealevel.com to receive access to the legacy driver download and installation instructions.

1.  Begin by locating, selecting, and installing the correct software from the Sealevel software driver database.
2.  Select the Part Number (#8208) for your adapter from the listing.
3.  Select the download for the SeaIO Classic for Windows (Software: SeaIO Classic V5 – Windows – Sealevel.) 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. 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 available to remove SeaIO files and registry/INI file entries from the system.
4. Go to the “Add New Hardware Wizard” in the Control Panel.
5. When the Wizard asks if you want Windows to search for the new hardware, choose “No, I want to select the hardware from a list.”
6. Scroll through the list of categorized hardware and select ‘SeaIO Devices.’ If this is the first SeaIO device you may need to select ‘Other Devices’ and ‘Sealevel Systems, Inc.’ instead of ‘SeaIO Devices.’
7. Click “Next.”
8. Select the card model and press “Next.”
9. The Wizard will guide you through a few more informational prompts; continue to click “Next” until it is completed.
10. Your card’s resource assignments may be adjusted through the Device Manager (if, for instance, you need to change the I/O port address Windows assigned when you installed the card).
11. Windows software installation is complete

Windows NT is not USB aware and thus cannot support the SeaLINK REL-16.

Physical Installation

The SeaLINK REL-16 can be installed in any open USB port.

Do not plug the unit into a USB port until the software has been fully installed.

• Simply connect the SeaLINK REL-16 to your USB port with the supplied cable.
• The software drivers installed during setup will automatically recognize and configure the device.
• You should see one or more “New Hardware Found” windows, indicating the actual device being created.
• Next, view your system’s Device Manager.
• You should have a new ‘SeaIO 8208’ in the SeaI/O Device heading indicating the installation was successful.

The SeaLINK REL-16 is now ready for use.

Programming the SeaLINK REL-16

Sealevel’s SeaI/O software is available to assist in the development of reliable applications for the Sealevel Systems family of digital I/O adapters. Included in Sealevel’s software 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 SeaLINK REL-16. 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.

Digital I/O Interface
The SeaLINK REL-16 provides two parallel input/output (I/O) ports. The ports are organized as ports A and B. The SeaLINK REL-16 is a line-powered device requiring a USB port capable of sourcing 500 mA.

Serial String
Each device has an eight digit alphanumeric serial string stored in non- volatile memory. On the Windows platforms, this number is used to give each unit a separate identity. This identity allows the device to be moved to any USB port or hub port on your computer while retaining its device number. If a device becomes damaged and is replaced the new device should be given the same serial string as the device it is replacing. This string is stored in an EEPROM along with other critical information. This EEPROM is read during enumeration. The device should not be unplugged during its enumeration due to remote possibility that the data in the EEPROM could be corrupted if power is removed during a read/write cycle to the EEPROM. Enumeration is complete when the LED is lit.
The control panel utility provides the capability to read or modify this string. However, setting the same string for two units connected to the same computer will cause the second unit to fail enumeration, and make it invisible to the operating system. Should this occur, unplug one unit, and set the serial string for the other unit to a different string.

Output Ports (Reed Relays)
Reed relays provide very high quality, long life, low power, dry contact switch closures. Reed relays are not suited for high current applications, or inductive loads. The relays are normally open, and close when energized. Writing a logic value of one or zero will change the state. Refer to the Application Programmers Interface for more information.
