The SeaLINK® single-port USB to RS-232 serial adapter utilizes Sealevel's expertise in military-grade designs by incorporating a ruggedized, overmolded enclosure into the 2105R. This improves the reliability and durability in industrial and mobile applications such as GPS navigation systems, barcode readers, signature input devices, serial printers, scales, and similar applications.

The 2105R features programmable baud rate and data formats with 128-byte transmit and 384-byte receive buffers. The USB serial adapter is compatible with all standard PC baud rates and supports high-speed communication to 921.6K bps. The 2105R is powered by the USB port and status LEDs molded into the enclosure indicate serial data activity and connection to the host.

Sealevel SeaCOM USB software drivers and utilities make installation and operation easy using Microsoft Windows and Linux operating systems. After installing the software, simply plug the 2105R 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.

The attached cable is approximately 56 inches long and fully shielded to protect the 2105R from RF and EMI interference that is common in mobile and industrial environments. Standard operating temperature range is 0 - +70C, and extended temperature range (-40C to +85C) is optional.

The 2105R has a DB-9M connector. If you need a DB-25M connector, order the 2101.
