BKM-20D SDI 4:2:2 Decoder Adaptor

The BKM-20D SDI 4:2:2 Decoder Adaptor is a video
signal input adaptor for BVM-Series video monitors.
When installed in an input option slot on the rear panel
of the video monitor, it provides video input and
output connectors for the monitor and a decoder for
serial digital component signals.

Functions

Decoder for Serial Digital Component
Signals
The BKM-20D is equipped with a decoder for serial
digital component (525/625) signals. If decoder
adaptors for analog composite signals are installed in
other input option slots, you can use them to decode
analog composite signals input to the BKM-20D.
Serial Digital and Analog Input and Output
Signal Connectors
The BKM-20D is equipped with three input and three
output connectors for serial digital signals, as well as
three input and three output connectors for analog
signals. Using the analog signal input connectors, you
can input one Y/R–Y/B–Y or one RGB signal, or three
analog composite signals. The types of analog
composite signals that may be input vary depending on
the input adaptors installed in other input option slots
(see page 20(E)).
Using the Input and Output
Connectors
For information about installing the BKM-20D in a video
monitor input option slot, see "Installing into Video
Monitors" (page 21(E)).
Note on using the BKM-20D
When installing adaptors, moving the analog input
connectors board, or fitting a cover plate over an
unused slot, always fit the BKM-20D as the last step
of the operation. If a BKM-20D is already installed,
remove it temporarily while carrying out the other
operations, then reinstall it last (see page 22(E)).

Input of serial digital component 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 !™ .
