Any serial signal, such as MIDI or Sony 9-pin (machine control) may be
transmitted through a MADI connection without losing any audio bandwidth
or microphone control of the remote I/O box. An RS422 connector labeled
‘Aux’ can be found on the MADI I/O card (hub frame side) as well as on the
serial card of the remote I/O frame. This card is located between slot 12 and
the power supplies. The required baud rate is set on the MADI I/O (local)
and MADI HD (remote) cards.
