DXLink Transmitter Audio SEND_COMMANDs
DXLink Transmitter Audio SEND_COMMANDs are sent to Port 7.
VIDIN_PHASE
Sets the input phase of the RGB video
input port addressed by the D:P:S.
NOTE:
This command applies to all
DXLink Transmitters except the
HDMI TX.
IMPORTANT:
Send to Port 8.
This command is valid only for inputs whose format is set to VGA.
Syntax:
SEND_COMMAND <DEV>,"'VIDIN_PHASE-<value>'"
Valid responses:
value = 0. . .31
Example:
SEND_COMMAND dvMFTX,"'VIDIN_PHASE-23'"
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'"
Valid response:
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 DX-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)
.
Syntax:
SEND_COMMAND <DEV>,"'AUDIN_FORMAT-<format>'"
Valid response:
format = HDMI, SPDIF, ANALOG
Example:
SEND_COMMAND dvTX,"'AUDIN_FORMAT-ANALOG'"
IMPORTANT:
The order of precedence (H
DMI 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.
NOTE:
S/PDIF signals are not available over the Wallplate TX or Decor Wallplate TX.
