The Protoss PW11-M provides an interface from RS485 to a WiFi network. The Protoss PW11-M integrates the TCP/IP controller, memory, WiFi connection with external antenna, RS485, and incorporates a fully developed TCP/IP network stack and the FreeRTOS operating system. Protoss PW11-M also includes an embedded web server used to configure the device.
The Protoss PW11-M, 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.
