z Data interface is a read‑only field that reports which of the CAT 5 (by default) or SFP
connectors is currently active on LAN 2.
z Multicast TTL (Time to Live) defines the number of hops multicast traffic makes between
routed domains when it exits a Source. If the TTL is not properly configured, information
that is to be sent back to a corresponding encoder may fail to function correctly.

The Output Format drop‑down list has three scaling modes (see figure 41
1
):
z Auto — sets the display to the same resolution and frame rate as the source stream.
z Monitor — sets the decoder output mode to the preferred resolution and frame rate
of the output monitor. To operate correctly, this feature requires the monitor to support
EDID properly.
z Fixed — sets the decoder output mode to the chosen resolution and frame rate as
selected from the Output Format drop‑down list.
NOTE: The scale option must be enabled whenever Monitor or Fixed output
formats are selected.
Enable or disable the
Nodata Splash, SoG, Scale, Genlock, Clean Switch and HDCP
mode
check boxes (see figure 41
2
).
z Selecting Nodata Splash enables the display of a splash screen when the display
detects a break in the input data stream. When disabled the last decoded frame is
displayed. After startup, when no last decoded frame exists a black screen is displayed.
z The SoG mode is not supported by the VND 250. Selecting this option has no effect.
z Selecting Scale enables scaling of the source image to the required resolution and
frame rate as defined by Monitor or the Fixed output format that is selected.
NOTE: Scaling is disabled when the output format is set to Auto.
