SeaLINK+2.SC User Manual
Introduction
Sealevel’s SeaLINK® 2223 USB to serial interface adapter offers an easy way to
connect two serial devices to a single USB port. All configuration and electrical
interface selections are handled through the driver, eliminating the need to open the
enclosure to set jumpers or switches. Each serial port is software configurable for
RS-232, RS-422, or RS-485 (full and half duplex) with the electrical interface
settings maintained locally, allowing the host computer to be repaired or upgraded
without reconfiguring the serial ports. Additionally, the 2223 can be configured at
one computer and deployed to other computers.
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 2223 into an available USB port and each
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.
To prevent accidental cable disconnection, the 2223 integrates a patent-pending
SeaLATCH locking 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. 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
Two DB9M connectors – each serial port supports data rates to 921.6K bps
Powered by USB host connection
Full modem control signals implemented in RS-232 mode
Status LEDs indicate power, electrical interface, and serial data activity
Flexible mounting options
DIN rail clips are available as an option

Hardware Installation
Do not connect the device to a USB port until the
software has been successfully installed.
To install the 2223, 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 4 times on two port devices). 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’.
Note: 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.
3. Click on ‘Finish’. Repeat this process for the remaining ports on the 2223.
