Introduction

The Sealevel Systems SeaLINK+232.PC equips the PC with a single USB to RS-232 Asynchronous serial

port and is intended for mounting directly to the PC’s chassis, eliminating the need for external converters

and providing a clean, professional installation. The board is USB bus powered and installs inside a low

profile computer chassis in a spare bracket location. The SeaLINK+232.PC includes a 14” USB header cable

(Item# CA260) that connects to most motherboard USB box header connectors and uses only one USB

port per serial port.

The SeaLINK+232.PC is designed to be used with a variety of Operating Systems including Windows

98/ME/2000/XP. The SeaCOM API (Application Programmer Interface) included on CD with the

SeaLINK+232.PC provides a variety of useful high-level function calls implemented as a Windows dynamic

link library (DLL). In addition to the API, SeaCOM includes sample code and utilities to simplify software

development.

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 SeaLINK+232.PC. All items can be purchased from our website (https://www.sealevel.com/)

or by calling 864-843-4343.

DB9 Female to DB25 Male 72” Standard RS-232 Cable (Item# CA177)

The CA177 connects to a DB9 Male serial port and converts it to a DB25 Male RS-232 connector.

DB9 Female to RJ45 Modular Adapter (Item# RJ9S8)

The RJ9S8 connects to any DB9 connector and converts it to an RJ45 connector, which allows the use of

standard twisted pair cabling. The RJ9S8 ships unassembled and can be configured for virtually any pin

Software Installation Instructions

Windows 98/ME/2000/XP/Vista™ Operating Systems

Do not connect the device to a USB port until the software is installed.

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

database.

2. Select the Part Number for your device from the listing.

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

components. Follow the information presented on the installation screens that follow.

4. 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.

5. During setup, you 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 included to remove the driver and all registry/INI

file entries from your system.

6. Proceed with the physical installation of your SeaLINK USB serial adapter.

Windows NT is not USB aware and thus cannot support this device.

3rd Party Software Support

Third party software support for many HMI/MMI and other process control software is included on the

product installation CD. For the most up to date information on third party software support, please visit

https://www.sealevel.com/support/3rd-party-software-support/.

Physical Installation

The SeaLINK+232.PC can be installed in any spare bracket location.

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

The SeaLINK+232.PC can be connected to any header type USB connector that supports the Intel assigned

connector pinout. The SeaLINK+232.PC will require no user hardware configuration. Once you have

installed the software simply plug the SeaLINK+232.PC into an available USB connector on the

motherboard. The drivers that were installed during setup will automatically be used to configure the

adapter. You should see one or more “New Hardware Found”, indicating the actual port being created. If

you view your systems’ Device Manager at this point, you should have a new “COM” port in the Ports (COM

& LPT) Device Class. You can access your new COM: port by using the assigned COM: identifier. This

assignment will vary from system to system. At this point, the hardware is recognized. To verify operation

use Sealevel Systems supplied WinSSD diagnostic utility. WinSSD can be found in the Start, Programs

group.

Technical Description

The SeaLINK+232.PC utilizes a USB UART. This chip features programmable baud rate, data format, 128

byte Dual Port TX Buffer, and 384 byte Dual Port RX Buffer. The RS-232 transceiver supports data rates up

to 460.8K baud. Refer to Appendix C for cable length limitations.
