Instruction Manual – DXLink™ Fiber Transmitters and Receivers, Duplex
Video SEND_COMMANDs (Transmitters), continued
?VIDIN_RES_REF
Requests the resolution and refresh
rate of the video through the
Transmitter.
Important:
Send to Port 7 for digital video and Port 8 for analog video.
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 dvTX,"'?VIDIN_RES_REF'"
Returns a COMMAND of the form:
VIDIN_RES_REF-<horizontal>x<vertical>,<rate>
Note:
If no signal is connected to the port being requested, then the response
will be
VIDIN_RES_REF-0x0,0
.
Note:
If analog video is currently routed and the resolution of the digital video
(Port 7) is requested, then the response will be
VIDIN_RES_REF-0x0,0
even
if digital video is present.
?VIDIN_PREF_EDID
Requests the preferred resolution of
the EDID source for the VGA video or
HDMI digital input.
Important:
Send to Port 7 for digital video and Port 8 for analog video.
Syntax:
SEND_COMMAND <DEV>,"'?VIDIN_PREF_EDID'"
Example:
SEND_COMMAND dvTX,"'?VIDIN_PREF_EDID'"
Returns a COMMAND of the form:
VIDIN_PREF_EDID-<resolution,refresh>
VIDIN_PREF_EDID
Sets the preferred resolution of the
EDID source for the VGA video or
HDMI digital input.
Important:
Send to Port 7 for digital video and Port 8 for analog video.
Syntax:
SEND_COMMAND <DEV>,"'VIDIN_PREF_EDID -<resolution,refresh>'"
Valid responses:
• resolution,refresh = <for supported input resolutions and refresh rates, see
the tables starting on page 119>
Examples:
SEND_COMMAND dvTX,"'VIDIN_PREF_EDID-1920x1080p,60'"
?VIDIN_EDID
Requests which EDID is being
presented to the source on the video
port addressed by the D:P:S.
Important:
Send to Port 7 for digital video and Port 8 for analog video.
Syntax:
SEND_COMMAND <DEV>, "'?VIDIN_EDID'"
Example:
SEND_COMMAND VIDEO_INPUT_1,"'?VIDIN_EDID'"
Returns a COMMAND of the form:
VIDIN_EDID-<source>
For the potential sources, see the VIDIN_EDID command.
VIDIN_EDID
Sets the EDID to be presented to the
source on the video port addressed by
the D:P:S.
Note:
For additional information on
EDID management and the EDID
variables used with this command, see
page 130.
Important:
Send to Port 7 or 8 unless specified otherwise.
Syntax:
SEND_COMMAND <DEV>,"'VIDIN_EDID-<source>'"
Valid responses:
source = ALL RESOLUTIONS, USER EDID 1*, USER_EDID_MODIFIED,
FULL-SCREEN, WIDE-SCREEN, MIRROR OUT 1**,
MIRROR_OUT_LOCAL (Port 7 only)
Example:
SEND_COMMAND VIDEO_INPUT_1,"'VIDIN_EDID-ALL RESOLUTIONS'"
* “USER EDID 1” must be written to the TX using DGX Configuration
Software (via the USB Program port) or to the DXLink Fiber Input Board.
** The HDMI port mirrors the downstream EDID of the connected DXLink
device. When connected to a DXLink Input Board, this EDID will be the same as
USER EDID 1.
