3.4 Power-up mode
Switch 8 on the configuration switch defines the power up mode. The sublime router
provides two modes for powering up the system.
The power up options can be switched according to the following pattern:
SW 8
Power Up mode
OFF
Switches all outputs according to the buffered
information in the routers processor system.
ON
Switches all outputs to input 1.
Default setting switches all outputs according to the buffered information in the routers
processor system.
3.5 Configuring switching time
This configuration is done in the Nevion Configurator.
It is possible to configure switching time in the router. The settings are made through the
Nevion Configurator, but a description of the options is given here. The user can select
between three options;
1. Switch according to detected sync reference signal (Default).
Switching time is determined by the synchronization signal that feeds the router. This is
useful when the video signal has the same format as the synchronization signal.
Supported formats are: PAL, NTSC, 750/50p, 750/60p, 1125/50i and 1125/60i.
2. Switch according to signal format: Select format.
Here it is possible to use one synchronization signal to switch a different video format. A
prerequisite is that the synchronization signal and the video signal have the same frame
rate. E.g. Use PAL as synchronization signal with a 750/50p video signal. Supported
formats are: PAL, NTSC, 750/50p, 750/60p, 1125/50i, 1125/60i, 1125/50p and
1125/60p.
We do not support 1125/50p or 1125/60p as synchronization signal. This means
that our 3G-HD routers cannot use default setting.
3. Switch to handle mixed signal formats.
The router switches 12us after vertical sync on the synchronization signal. This will
occur in line 1 on all video formats. This is useful when you have different video formats
on the same router, also with different frame rate.
This setting is not according to recommendations in SMPTE RP 168-2002.
