Description
The Sealevel 2123-OEM serial interface adapter provides one software configurable RS-232, RS-422, or RS-485 port via an internal USB connection. All configuration and electrical interface selections are handled through the driver, eliminating the 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.
Sealevel SeaCOM USB software drivers and utilities make installation and operation easy using Microsoft Windows operating systems. After installing the software, simply connect the 2123-OEM to an internal USB header connector, and then boot the system. 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 921.6Kbps. Status LEDs on the board indicate power, serial data activity, and electrical interface.
The 2123-OEM is USB bus-powered, so no external power supply is needed. A 2mm 4-pin Molex vertical header provides an internal USB connection to your host system. For EBX and larger motherboards with a 0.1 onboard USB header, order the CA260 internal USB cable. For smaller motherboards with a 2mm onboard USB header, order the CA383 internal USB cable. Standard operating temperature range of SeaLINK adapters is 0°C to 70°C and extended temperature range (-40°C to 85°C) is optional.
