When ACOHD6800 module is in normal status, plug out the module and
the output signal will switch to a backup channel signal, the switching time
is less than 2s. Then if the module is plugged in, the output signal will
switch to the latest output signal source, and the switching time is less than
2s.

Comments
Set as the primary signal
source, the signal is normally
direct as the output signal
source.
Set as the secondary signal
source, the signal will be direct
as the output signal source
when IN1 is fault.
Set as the third signal source,
the signal will be direct as the
output signal source when IN2
is fault.
Set as the reference signal
source,
usually
image, such as color stripe, test
chart as this signal. it can be
output to SDI OUT manually
when the other three signals
were all fault.
For external synchronization,
connect a synchronous signal
to REF IN
Output the selecting signal
source. When the module was
pulled out or power failure, the
SDI IN1 will be selected as the
signal source and output. Video
loop output with clock recovery.
Connect to a remote control
panel or other control devices
for remoter control via this
interface
