Command Description
AUDIN_FORMAT
Selects the audio input source
that will be embedded on the
HDMI signal through the TX.
Note: When the TX is set to
route digital video (Port 7),
you can select from the HDMI,
SPDIF, or ANALOG audio
inputs. When the TX is set to
route analog video (Port 8),
you can select the SPDIF or
ANALOG audio input (see the
VI<input>O<output>
command on previous page.
Note: S/PDIF signals are not
available over the Wallplate
TX.
Syntax:
SEND_COMMAND <DEV>,"'AUDIN_FORMAT-<format>'"
Variable:
format = HDMI, SPDIF, ANALOG
Example:
SEND_COMMAND dvTX,"'AUDIN_FORMAT-ANALOG'"
Important: The order of precedence (HDMI embedded audio, S/PDIF,
analog) can be overridden with this command; however, you must first send
a disable command (AUDIN_FORMAT_AUTO-DISABLE) to disable the
auto format function, or the audio format will automatically switch back
anytime the order of precedence is violated.
Channel Function
