The Protoss-PE11 is an RS485 to TCP/IP interface gateway.

The Protoss-PE11 integrates a TCP/IP controller, memory, a 10/100M Ethernet transceiver, RS485, and a fully developed TCP/IP network stack and FreeRTOS operating system. The Protoss-PE11 also includes an embedded web server used for configuring the device.
The Protoss-PE11, using a highly integrated hardware and software platform, has been optimized for all types of applications in industrial control, smart grid, personal medical applications, and remote control that have lower data transmission speeds and transmit or receive data on an infrequent basis.
