Specifications - Sony BKM-21D Installation Manual

BKM-21D SDI Multi Decoder Adaptor
Input of serial digital signals
You can input serial digital signals to connectors 1,
3, and 5. You can obtain active loop-through output
of those signals from connectors 2, 4, and 6,
respectively.
You need not attach 75-ohm terminations to
connectors 2, 4, and 6.
Input of analog composite signals
You can input analog composite signals to connectors
7, 9, and !¡. You can obtain loop-through output of
those signals from connectors 8, 0, and !™ ,
respectively. If you do not wish to use loop-through
output, attach 75-ohm terminators to connectors 8,
0, and !™ .
Input of Y/R–Y/B–Y or RGB signals
You can input a Y or G signal to connector 7, an B–Y
or B signal to connector 9, and a R–Y or R signal to
connector !¡. You can obtain loop-through output of
those signals from connectors 8, 0, and !™ ,
respectively. If you do not wish to use loop-through
output, attach 75-ohm terminators to connectors 8,
0, and !™ .
Assigning Input Signals to Connectors
Before inputting signals to the BKM-21D, you must
specify the type and format of the signal that will be
input to each connector. To assign input signals to
each connector, use the on-screen INPUT
CONFIGURATION menu of your video monitor.
For information about using the INPUT CONFIGURATION
menu, refer to the manual of your video monitor.
