Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
Video SEND_COMMANDs (Transmitters), continued
VIDIN_RES_REF
Sets the resolution and
refresh rate of the video
through the Transmitter
(disable VIDIN_RES_AUTO
prior to sending).
Important:
Send to Port 7 or Port 8.
Syntax:
SEND_COMMAND <DEV>,"'VIDIN_RES_REF- <horizontal>x<vertical>,<rate>'"
Variables:
• 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.
?VIDIN_PREF_EDID
Requests the preferred
resolution of the EDID source
for the VGA video input.
Note:
This command applies
to all DXLink Transmitters
except the HDMI TX.
Important:
Send to Port 8.
Syntax:
SEND_COMMAND <DEV>,"'?VIDIN_PREF_EDID'"
Example:
SEND_COMMAND dvMFTX,"'?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 input.
Note:
This command applies
to all DXLink Transmitters
except the HDMI TX.
Important:
Send to Port 8.
Syntax:
SEND_COMMAND <DEV>,"'VIDIN_PREF_EDID - <resolution,refresh>'"
Variable:
• resolution,refresh = <for supported input resolutions and refresh rates, see the tables
starting on page 126>
Examples:
SEND_COMMAND dvMFTX,"'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 8.
Syntax:
SEND_COMMAND <DEV>, "'?VIDIN_EDID'"
Example:
SEND_COMMAND VIDEO_INPUT_1,"'?VIDIN_EDID'"
Returns a COMMAND of the form:
VIDIN_EDID-<source>
See the VIDIN_EDID command for the potential sources.
VIDIN_EDID
Sets the EDID to be
presented to the source on
the video input port
addressed by the D:P:S.
Important:
Send to Port 8 (or Port 7 - only for the last variable listed).
Syntax:
SEND_COMMAND <DEV>,"'VIDIN_EDID-<source>'"
Variables:
source = ALL RESOLUTIONS, USER EDID 1* (Port 8 only)
MIRROR OUT 1** (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 (see
page 140).
** The HDMI port mirrors downstream EDID of the connected DXLink device.
Tip:
For troubleshooting purposes,
“
MIRROR OUT 1” can be sent to Port 7 of the TX
(or Port 6 of the RX), which effectively acts like a hotplug and refreshes the EDID.
?VIDIN_HDCP
Requests the video HDCP
compliance of the video input
port addressed by the D:P:S.
Important:
Send to Port 7.
Syntax:
SEND_COMMAND <DEV>,"'?VIDIN_HDCP'"
Example:
SEND_COMMAND dvTX,"'?VIDIN_HDCP'"
Returns a COMMAND of the form:
VIDIN_HDCP-<ENABLE|DISABLE>
