Introduction

Overview

Sealevel’s SeaLINK 2823 USB to serial interface adapter offers an easy way to connect up to eight serial

devices to a single USB port. All configuration and electrical interface selections are handled through the

driver and each port is individually software configurable for RS-232, RS-422, or RS-485 (full and half duplex).

Sealevel’s SeaCOM USB software drivers and utilities package makes installation and operation easy for

Windows 98, ME, 2000, XP, and Vista operating systems. Once the software is installed, plug the 2823 into

an available USB port and each port is recognized as a standard COM port by the host system; this feature

enables compatibility with legacy software. The devices maintain their electrical interface settings locally,

allowing the host computer to be repaired or upgraded without reconfiguring the serial ports. Additionally,

the devices can be configured at one computer and deployed to other computers.

To prevent accidental cable disconnection, the 2823 integrates a SeaLATCH USB port, which is fully

compatible with standard USB cables. When used with the included USB cable with a SeaLATCH USB type

B connector, the metal thumbscrew provides a secure connection to the device. The highly retentive USB

Type B connector also helps prevent unintentional separation from a standard USB cable. Standard

operating temperature range is 0°C to 70°C and extended temperature range (-40°C to +85°C) is optional.

Status LEDs display electrical interface selection and serial data activity for each port.

Features

•Each port is individually software configurable for RS-232, RS-422, and two-wire or four-wire RS-

485

•Electrical interface settings maintained across multiple computers

•High speed UART with 128-byte Tx FIFO and 384-byte Rx FIFO

•Automatic hardware RS-485 enable/disable

•Each serial port supports data rates to 921.6K bps

•Powered by USB host connection

•Eight DB9M connectors with full modem control signals implemented in RS-232 mode

•Status LEDs indicate power, electrical interface, and serial data activity for each port

Male pinout. This cable is ten inches in length.

Terminal Blocks

Terminal Block –DB9F to 9 Screw Terminals

(Item# TB05)

The TB05 terminal block breaks out a DB9 connector to

nine screw terminals to simplify field wiring of serial

connections including RS-422 and RS-485 networks. The

TB05 is designed to connect directly to Sealevel DB9

serial cards or any cable with a DB9M connector.

Terminal Block –Dual DB9F to 18 Screw Terminals

(Item# TB06)

The TB06 terminal block breaks out dual DB9

connectors to 18 screw terminals to simplify field wiring

of serial connections including RS-422 and RS-485

networks. The TB06 is designed to connect directly to

Sealevel dual port DB9 serial cards or any cable with

DB9M connectors.

Adapters and Converters

DB9F to RJ45 Modular Adapter

(Item# RJ9S8)

Installation & Configuration

Software Installation

Windows Installation

Do not install the Adapter in the machine 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

[email protected]om to receive access to the proper 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 (2823) for your device from the listing.

3. Click the ‘Install Drivers’ button.

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

components.

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

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

You are now ready to proceed with connecting the 2823 to your system. Refer to the Hardware

Installation section for details.

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

Hardware Installation

Do not connect the device to a USB port on your motherboard until the software has been

successfully installed.

To install the 2823, plug the device into an available USB port using the supplied USB cable. The following

instructions were tested with Windows XP and may vary based on your version of Windows.

Once the device has been connected, the Found New Hardware wizard will appear first for the root hub

and then for each port that you are installing. Follow the instructions on the following page to finish

installation.

The installation will repeat twice for each COM port (a total of 16 times on the SeaLINK+8.VC). This

is a limitation in the way Windows installs external serial devices.

1. Click on ‘Install the software automatically’ followed by the ‘Next’ button.

2. Windows will show a warning message that the hardware has not passed Windows logo

testing. Click on ‘Continue Anyway’.

3. Click on ‘Finish’. Repeat this process for the remaining ports on the 2823.

The SeaLINK +8.SC is now ready for use.

All applications and drivers have been fully tested to maintain the integrity of your operating system.

Clicking on ‘Continue anyway’ will not harm your system in any way.

Verifying Installation

To confirm that the drivers have been successfully installed, you can look in Device Manager under ‘Ports

(COM &LPT)’ and each of the ports you installed will be included on the list with their associated COM

numbers. To access Device Manager, follow the steps below:

1. Right-click on the ‘My Computer’ icon on your desktop or in the Start menu.

2. Click on ‘Properties’ in the fly out menu to launch the ‘System Properties’

window.

3. Click on the ‘Hardware’ tab and then click on the ‘Device Manager’ button.

4. When Device Manager launches, look under ‘Ports (COM & LPT)’ to verify that

the serial ports have been correctly installed (screen shot of 2833 shown).

Your system will assign the next available COM numbers which may vary for each computer used.

Hardware Configuration

Electrical Interface Mode Selection

The 2823 offers RS-232, RS-422, and RS-485 (full and half duplex) modes. The electrical interface is a

software selectable feature that can be accessed and changed using the Sealevel SeaCOM driver via Device

Manager. To select the electrical interface, follow the steps below:

1. Open Device Manager and locate ‘Ports (COM&LPT)’ following the steps above. You should

see each of the 2823’s ports listed.

2. Select one of the ports by right-clicking on it and selecting ‘Properties’ from the fly out menu.

The serial port properties menu will appear

3. Click on the ‘Interface Settings’ tab

The Sealevel SeaCOM driver adds the ‘Interface Settings’ tab. If this tab is missing, SeaCOM is not

correctly installed.

4. Select the appropriate electrical interface for your application and click on ‘OK’.
