Note1: The AUX interface of
L-

SDI-FE-HD-TX
and
L-
2
SDI-FE-HD-RX
are used in pairs, e.g. if
L-
2
SDI-FE-
HD-TX
use 2-channel unidirectional audio output interface,
L-
2
SDI-FE-HD-RX
should use 2-channel
unidirectional audio input interface.
Note2: If the auxiliary channel is used as the audio channel, the embedded audio channel in the HD-SDI
signal will be unavailable.
