The SeaLINK 2223 USB to serial interface adapter offers an easy way to connect two serial devices to a 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, and RS-485 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 using Windows 98SE, ME, 2000, XP and Vista operating systems.

After installing the software, simply plug the 2223 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.

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. Status LEDs on the front of the enclosure indicate power, serial data activity, and electrical interface.

The adapter integrates a SeaLATCH locking USB port, which is fully compatible with standard USB cables. When used with the included USB cable with a locking type B connector, the metal thumbscrew provides a secure connection to the device and prevents accidental cable disconnection.

The 2223 is housed in a rugged, plastic enclosure ideal for mounting on walls, under counters, or inside panels. DIN rail clips are available as an option.

The adapter is USB bus powered, so no external power supply is needed. Standard operating temperature range is 0°C to 70°C and extended temperature range (-40°C to 85°C) is optional.
