The RS232 protocol is defined to support the standard features on a Neets Echo control panel.

The user can find in the Neets Device Editor Application version 

 The RS232 Control Protocol allow control over:
Volume control
Mute control
DSP Matrix control (and thereby source-selection)
Status readings
The LUCIA RS232 protocol uses 9600 bit/s, 8 databit, no parity and 1 stopbit, please have in to consideration that flow control, software or hardware is not employed.
All commands/responses are in clear ASCII text and must be terminated with a <CR> Carriage Return (0x0D).
Regarding synchronization a single <CR> can be used to empty the LUCIA command buffer to synchronize further communications.
In the case of receiving an unknown command string, it will respond with “ERROR UNKNOWN COMMAND”.
