More info

Data transfer rates up to 1,000,000 baud (1 MegaBaud), coupled with 1Mbit/s line drivers deliver uncompromising performance. Baud rates can be standard values such as 9,600, 115,200, 230,000, 921,600 or user definable non standard values. Power over Ethernet (PoE) uses IEEE 802.3af standard, compatible with any PoE switch.

A web interface allows secure configuration and control of the serial ports over a local network or the internet using any browser.

Serial Port Tunnelling (individually configurable) allows serial cable replacement over any distance, no software required. You can access the device via TCP/IP sockets from any networked device like an Android tablet, PC or phone. On Windows OS TCP/IP sockets are handled by the Winsock API, this will differ on other OSs.
