9.10.2. Enable Forced Link Training
Command and Response #linktraining
SET·/MEDIA/PORTS/VIDEO/<out>/SETTINGS.DpForcedMode=<forced_mode>
Ý
pw·/MEDIA/PORTS/VIDEO/<out>/SETTINGS.DpForcedMode=<forced_mode>
Ü
Parameters
Identifier Parameter description
<forced_mode> It allows to configure the output link
training parameters (Link datarate, Link
lane, Swing / pre-emphasis) manually,
the link training process is skipped.
Example
Ý SET /MEDIA/PORTS/VIDEO/O1/SETTINGS.DpForcedMode=true
Ü pw /MEDIA/PORTS/VIDEO/O1/SETTINGS.DpForcedMode=true
GET command.
Parameter values
true: The matrix sends 1.5W power on the
chosen port.
false: The matrix does not provide any power
on the chosen port.
Parameter values
true: The link training mode is Forced. Link
datarate, Link lane count and Swing / pre-
emphasis parameters can be modified.
false: The link training mode is Automatic.
The matrix and the agree the link training
parameters automatically without any user
interruption.
