EXBOX.AES Manual - Version 2.0
Chapter 1: Overview
The local RS 232 port offers bidirectional transport of
serial data that is embedded in the user bits of audio
channels 1-9.
The embedder / de-embedder handles four different
baud rates. Further it can be switched off to process
user bits of the AES inputs or it can be bypassed to
preserve user bits of the MADI input signal.
NOTE
A MADI signal transports 64 audio channels. There
are four banks with 16 channels each (4 x 16 = 64).
