SL9205 Revision 2/2009 SeaLINK+2/PC.SC User Manual
Introduction
Sealevel’s SeaLINK® 2228 is a dual-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. Each serial port is
individually 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 ports.
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 2228 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.
The 2228 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
Each port is individually software configurable for RS-232, RS-422, and two-
wire or four-wire RS-485
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
Includes 14” internal USB header cable (Item# CA260)
