Aux Data
RS232: There is one RS232 port for use as auxiliary data port. This
port allows the reception of data along with the encoded audio.
When one option is checked, the corresponding decoder will allow
the reception of ancillary data.
The auxiliary data can be received via a different path, different
from the audio one (Aux. data embedded in audio). This method
has 3 big advantages: less delay independent from the audio
codification delay; the possibility to send/receive auxiliary data
regardless of the compression mode used for the audio
communication; and the possibility to send/receive the User bit of
the AES/EBU frame. The drawback is that the audio and data delay
won’t be the same

Before version 4.8.1, auxiliary data could only be sent embedded into the audio frame, for
those compression modes which accept it. From version 4.8.1 to version 5.2.1, the auxiliary data
could only be sent on a different IP path, and from version 5.2.1 onwards, it is possible to select
between both ways of operation.
