Introduction
Overview
The Sealevel’s SeaLINK 2433 USB to serial interface adapter provides RS-232, RS-422, or RS-485 serial
ports via USB and is ideal for rugged and industrial environments. 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 2433 into
an available USB port and each serial port is recognized as a standard COM port by the host system
enabling 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.
Two convenient USB 1.1 hub ports are included on the front of the enclosure for easily connecting
additional SeaLINK devices or standard USB peripherals. The 2433 integrates three SeaLATCH USB ports,
which are fully compatible with standard USB cables. The metal thumbscrew on the included USB cable
with a SeaLATCH USB type B connector provides a secure connection and prevents accidental cable
disconnection. Additionally, the highly retentive type B connector 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
•+5VDC input power passed through on pin 9 of each DB9M connector and fused at
500mA for powering serial peripherals
•Includes two powered, fully rated (500mA) USB 1.1 downstream hub ports
•Automatic hardware RS-485 enable/disable
•Each serial port supports data rates to 921.6K bps
•Four DB9M connectors
•Status LEDs indicate power, electrical interface, and serial data activity for each port

Installation & Configuration
Software Installation
Windows 98/ME/2000/XP/Vista™ Operating Systems
1. Begin by locating, selecting, and installing the correct software from the Sealevel software driver
database.
2. Select the Part Number (2433) 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 2433 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 2433, first power the device using the included wall-mount power supply. Next, plug the device
into an available USB port using the supplied USB cable. Once both the power and USB connections are
secure the green power LED will light. 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 USB 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 2433.
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.
