 This module implements a Python client for the Russound I/O (RIO) protocol used to control Russound audio controllers. RIO supports a superset of the RNET feature set, allows for push notifications of system changes and supports TCP/IP and RS232 communication.

+
+## Communication
+The library supports the RIO protocol communication over TCP/IP or RS232 (Serial). 
+
+### TCP/IP
+The built-in ethernet port on the Russound device natively support the RIO protocol. **Note:** It is strongly recommended that the controller has a static IP address configured.
+
+### RS232 (Serial)
+
+The RS232 port must be configured to use the RIO protocol instead of the RNET protocol for the library to function properly. This can be configured using the SCS-C5 configuration tool or the controller's Web GUI.

 ## Acknowledgements
 This is the continuation of the `russound_rio` package. This wouldn't be possible without the excellent work from [@wickerwaka](https://github.com/wickerwaka) and [@chphilli](https://github.com/chphilli).
