Table 4-2: Input Modes and Signal Connections
If a new signal is connected that conflicts with the present mode setting, it will not be transmitted by the
7707VT-4-HS. The corresponding Signal Status LED will be yellow, indicating a signal conflict on that
channel. The 7707VT-4-HS will NOT drop or otherwise interrupt any of the existing signals in the event
that a new conflicting signal is connected.
The
AUTO
input mode will automatically select the optimum input mode (
HHXX
,
HSSS
or
SHSS
) depending
on the signals that are connected to the 7707VT-4-HS. If a signal is connected that the 7707VT-4-HS
cannot accommodate in any of the above modes, the Signal Status indicator corresponding to that
channel will be yellow. The 7707VT-4-HS will NOT drop or otherwise interrupt any of the existing signals
in the event that a new conflicting signal is connected.
Whether the input mode is selected automatically or manually by the user, it may be displayed by the
MODE
selection under the
STAT
4.2.7. Setting Video Error Detection
