Audio SEND_COMMANDs (Transmitters)
Command
Description
?AUDIN_FORMAT_AUTO
Requests the setting (Enable
or Disable) for automatically
detecting the audio source
format through the TX.
Syntax:
SEND_COMMAND <DEV>,"'?AUDIN_FORMAT_AUTO'"
Example:
SEND_COMMAND dvTX,"'?AUDIN_FORMAT_AUTO'"
Returns a COMMAND of the form:
AUDIN_FORMAT-AUTO<ENABLE|DISABLE>
AUDIN_FORMAT_AUTO
Sets audio source format to
automatically detect the audio
through the TX.
Syntax:
SEND_COMMAND <DEV>,"'AUDIN_FORMAT_AUTO-
<ENABLE|DISABLE>'"
Example:
SEND_COMMAND dvTX,"'AUDIN_FORMAT_AUTO-ENABLE'"
?AUDIN_FORMAT
Requests the setting for the
audio source format.
Syntax:
SEND_COMMAND <DEV>,"'?AUDIN_FORMAT'"
Variable:
format = HDMI, SPDIF, ANALOG
Example:
SEND_COMMAND dvTX,"'?AUDIN_FORMAT'"
Returns a COMMAND of the form:
AUDIN_FORMAT-<format>
AUDIN_FORMAT
Selects the audio input source
that will be embedded on the
HDMI signal through the TX.
Note:
When the Multi-Format
TX is set to route digital video
(input 7), you can select from
the HDMI, SPDIF, or ANALOG
audio inputs. When it is set to
route analog video (input 8),
you can only select the SPDIF
or ANALOG audio input
(see the VI<input>O<output>
command).
Note:
S/PDIF signals are not
available over the Wallplate
TX or Decor 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
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.
