BBG-S2ENET Serial to Ethernet Adapter

The BBG-S2ENET Serial to Ethernet Adapter (S2ENET) is a compact integrated solution to enable network connection to any device with a standard serial interface. The S2ENET allows OEMs to add Ethernet connectivity to existing products by simply adding a small circuit card.

The BBG-S2ENET operates on 3.3Vdc – 5Vdc power to convert between serial RS-232 or RS-422 interfaces and Ethernet interfaces. To allow connection to a local network or the Internet, the S2ENET converter integrates a fully developed TCP/IP network stack and OS. The BBG-S2ENET also includes an embedded web server that can be used to remotely configure, monitor, or troubleshoot devices. Onboard flash memory allows storage of configuration, operational, maintenance, and calibration data that can be displayed on any web browser. The S2ENET also offers three programmable I/O pins allowing input, output or control of digital circuitry.
