Introduction

Sealevel’s SeaLINK® 2128 is a single-port embedded USB to multi-interface serial adapter intended for

mounting directly to a computer chassis, eliminating the need for an external converter, and providing a

clean, professional installation. All configuration and electrical interface selections are handled through the

driver, so you never need to open the enclosure to set jumpers or switches. The serial port is software

configurable for RS-232, RS-422, and RS-485 with the electrical interface settings maintained locally,

allowing the host computer to be repaired or upgraded without reconfiguring the serial port.

Sealevel SeaCOM USB software drivers and utilities make installation and operation easy for Windows 98SE,

ME, 2000, XP, and Vista operating systems. Once the software is installed, plug the 2128 into an available

USB port and the serial port is recognized as a standard COM port by the host system enabling compatibility

with legacy software. Serial data rates to 921.6K bps are supported.

The 2128 includes a standard sized PC bracket and ships with an internal USB cable (Item# CA260) that is

compatible with many EBX and larger sized motherboards with 0.1" USB header connectors. For EPIC and

smaller sized motherboards, an internal USB cable with a 2mm header connector (Item# CA383) is

available as an option. Standard operating temperature range is 0°C to 70°C and extended temperature

range (-40°C to 85°C) is optional.

Features

•Serial port is software configurable for RS-232, RS-422, and two-wire or four-wire RS-485

3RD PARTY SOFTWARE SUPPORT

For the most up to date information on third party software support, please visit

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

Hardware Installation

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

successfully installed.

The 2128 requires no user hardware configuration and can be installed in any spare PC bracket location.

To install the 2128, locate an available PC slot in your system. Remove the blank plate and install the 2128

and secure the screw or tab (included with your system). Alternately, the bracket can be removed, and the

board can be panel mounted. Connect the embedded USB cable to the board and plug into an available

USB header connector on the motherboard.

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

Once the device has been installed, power up the system. 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 (twice on single port devices). This is a

limitation in the way Windows installs USB serial devices.

1. A ‘Found New Hardware’ alert will appear above the system tray (the single port model name will

be “SeaLINK/PC.SC”).

2. The ‘Found New Hardware Wizard’ will appear.

3. Choose ‘No, not this time’ and click ‘Next’ to proceed.

4. Choose ‘Install the software automatically’ and click ‘Next’ (the single port model name will be

“SeaLINK/PC.SC”).

5. The ‘Hardware Wizard’ will search for the proper drivers; however, it may be interrupted by a message

stating that the hardware has not passed Windows certification. Click on ‘Continue Anyway’.

All SeaCOM software and drivers have been fully tested by Sealevel. Clicking ‘Continue anyway’

will not harm your system.

6. The appropriate drivers for your SeaLINK device and version of Windows will be installed as shown

(the single port model name will be “SeaLINK/PC.SC”).

7. Click ‘Finish’ to complete the installation of your hardware (the single port model name will be

“SeaLINK/PC.SC”).

8. The ‘Found New Hardware Wizard’ appears a second time; repeat steps 4-8.

9. When the ‘Found New Hardware’ alert informs you that your hardware is installed and ready to use,

you can proceed with verifying the installation to check functionality and/or locate the COM port

assignments, if necessary.
