Hardware Reference Manual – DXLink™ Twisted Pair Transmitters/Receiver
?INPUT-VIDEO
Requests the video input being used
on the DX-TX, Wallplate TX, or Decor
Wallplate TX: either the digital video
(Input 7) or the analog video
(Input 8).
The output is always 6.
NOTE:
This command applies to all
DXLink Transmitters except the
HDMI TX.
IMPORTANT:
This command must be sent to Port 1.
Syntax:
SEND_COMMAND <DEV>,"'?INPUT-VIDEO,6'"
Example:
SEND_COMMAND dvMFTX,"'?INPUT-VIDEO,6'"
Returns a COMMAND of the form: SWITCH-LVIDEOI8O6
VI<input>O<output>
Sets the DX-TX, Wallplate TX, or
Decor Wallplate TX to route either the
digital video (Input 7) or the analog
video (Input 8) to the output (which
is always output 6).
NOTE:
This command applies to all
DXLink Transmitters except the
HDMI TX.
IMPORTANT:
This command must be sent to Port 1.
Syntax:
SEND_COMMAND <DEV>,"'VI<input>O<output>'"
Valid responses:
• input = 7 for digital video; 8 for analog video
• output = 6
Example:
SEND_COMMAND dvMFTX,"'VI8O6'"
?VIDIN_STATUS
Requests the status of the video
input on the Transmitter.
IMPORTANT:
Send to Port 7 for digital video or to Port 8 for analog video.
Syntax:
SEND_COMMAND <DEV>,"'?VIDIN_STATUS'"
Valid response:
status = NO SIGNAL, UNKNOWN SIGNAL, VALID SIGNAL
Example:
SEND_COMMAND dvMFTX,"'?VIDIN_STATUS'"
Returns a COMMAND of the form: VIDIN_STATUS-<status>
?VIDIN_FORMAT
Requests the video format on the
Transmitter.
NOTE:
All DXLink Transmitters
except the HDMI TX s
upport
component, S-Video, composite,
and VGA signals.
NOTE:
Send to Port 7 or Port 8.
Syntax:
SEND_COMMAND <DEV>,"'?VIDIN_FORMAT'"
Valid response:
• format (port 8) = COMPONENT, S-VIDEO, COMPOSITE, VGA
• format (port 7) = HDMI, DVI
Example:
SEND_COMMAND dvMFTX,"'?VIDIN_FORMAT'"
Returns a COMMAND of the form: VIDIN_FORMAT-<format>
VIDIN_FORMAT
Sets the video format on the
Transmitter (prior to sending,
VIDIN_AUTO_SELECT must be set to
DISABLE).
NOTE:
All DXLink Transmitters
except the HDMI TX su
pport
component, S-Video, composite,
and VGA signals
NOTE:
Send to Port 7 or Port 8.
Syntax:
SEND_COMMAND <DEV>,"'VIDIN_FORMAT-<format>'"
Valid response:
• format (port 8) = COMPONENT, S-VIDEO, COMPOSITE, VGA
• format (port 7) = HDMI, DVI
Example:
SEND_COMMAND dvMFTX,"'VIDIN_FORMAT-COMPONENT'"
?VIDIN_RES_REF
Requests the resolution and refresh
rate of the video through the
Transmitter.
NOTE:
Send to Port 7 or Port 8.
Syntax:
SEND_COMMAND <DEV>,"'?VIDIN_RES_REF'"
Valid responses:
• horizontal = An integer value representing the horizontal.
• vertical = An integer value representing the vertical. May have an additional qualifier such as
'i' or 'p'.
• rate = An integer value representing the refresh rate.
Example:
SEND_COMMAND dvMFTX,"'?VIDIN_RES_REF'"
Returns a COMMAND of the form:
VIDIN_RES_REF-<horizontal>x<vertical>,<rate>
