IV.2.1.15. Auxiliary data
The Streaming Aux Data Menu allows establishing auxiliary data channels
associated to each communication using the RS232 serial ports.
It is also possible to embed the auxiliary data in the audio streams when the
compression format allows this possibility.
IV.2.2 Interfaces options menu
In this menu several communication interfaces can be configured: Ethernet, Wi-
Fi, 3G/4G services for audio communications, and RS232 and GPIO for the
transmission of auxiliary data. There’s also an option for controlling the
bandwidth consumption in each interface.
