BKM-120D SDI 4:2:2 Input Adaptor
The BKM-120D SDI 4:2:2 Input Adaptor is a video
signal input adaptor for BVM-D9H/D14H 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-120D is equipped with a decoder for serial
digital component (525/625) signals.
Serial digital input and output signal
connectors
The BKM-120D is equipped with two input and two
output connectors for serial digital signals.
Active loop-through output (only terminals
with the
mark)
Digital signals connected to the input connectors are
output.
Note
Digital signals are available only when the power of
the video monitor is ON.
Using the Input and Output
Connectors
For information about installing the BKM-120D in a video
monitor input option slot, see "Installing into Video
Monitors" on page 11(E).

Input of serial digital component signals
You can input serial digital signals to connectors 1
and 3. You can obtain active loop-through output of
those signals from connectors 2 and 4, respectively.
You need not attach the 75-ohm termination to
connectors 2 and 4.
Assigning input signals to connectors
Before inputting signals to the BKM-120D, 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 CONFIG
menu of your video monitor.
For information about using the INPUT CONFIG menu,
refer to the manual of your video monitor.
Note
After assigning input signals to each connector, carry
out the AUTO adjustment of the CONTROL PRESET
ADJ menu.
