Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
DXLink Transmitter Audio SEND_COMMANDs
DXLink Transmitter Audio SEND_COMMANDs are sent to Port 7.
Video SEND_COMMANDs (Transmitters), continued
?VIDIN_PHASE
Requests 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'"
Example:
SEND_COMMAND dvMFTX,"'?VIDIN_PHASE'"
Returns a COMMAND of the form:
VIDIN_PHASE-<value>
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>'"
Variables:
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'"
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).
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.
Note:
S/PDIF signals are not available over the Wallplate TX or Decor Wallplate TX.
