SeaLINK/PC.SC: USB to 1 Port RS-232/422/485, Software Config

The 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 ports.

Sealevel SeaCOM USB software drivers and utilities make installation and operation easy using Microsoft Windows operating systems. After installing the software, simply connect the 2128 to an available USB header connector on your motherboard and the serial port is recognized as a standard COM port by the host system enabling compatibility with legacy software. All Sealevel SeaLINK USB serial adapters use a state-machine architecture that greatly reduces the host computer’s overhead when communicating over multiple serial ports simultaneously while supporting data rates to 921.6K bps.

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.
