Hardware Reference Manual – DXLink™ Twisted Pair Transmitters/Receiver
VIDIN_RES_REF
Sets the resolution and refresh rate
of the video through the Transmitter.
IMPORTANT:
Send to Port 7 or Port 8.
Syntax:
SEND_COMMAND <DEV>,"'VIDIN_RES_REF- <horizontal>x<vertical>,<rate>'"
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.
?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>'"
Valid response:
resolution,refresh = <for supported input resolutions and refresh rates, see the tables starting
on page 107>
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 valid response listed).
Syntax:
SEND_COMMAND <DEV>,"'VIDIN_EDID-<source>'"
Valid responses:
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 120).
** 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>
