BKM-28X Analog Input Expansion Adaptor

The BKM-28X Analog Input Expansion 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.

Functions

Expansion of Analog Composite Inputs
The BKM-28X is not equipped with decoders, but if
decoder adaptors are installed other input option slots,
you can use them to decode analog composite signals
input to the BKM-28X.
Expansion of analog component inputs is also
possible.
Analog Input and Output Signal
Connectors
The BKM-28X is equipped with six input and six
output connectors. You can input two Y/R–Y/B–Y,
RGB or YC signals, or six analog composite signals to
the input connectors. 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-28X in a video
monitor input option slot, see "Installing into Video
Monitors" (page 21(E)).

Input of analog composite signals
You can input analog composite signals to connectors
1, 3, 5, 7, 9, and !¡. You can obtain loop-
through output of those signals from connectors 2,
4, 6, 8, 0, and !™ , respectively. If you do not wish
to use loop-through output, attach 75-ohm terminators
to connectors 2, 4, 6, 8, 0, and !™ .
Input of Y/R–Y/B–Y, RGB, or YC signals
When inputting Y/R–Y/B–Y or RGB signals, you can
input Y or G signals to connectors 1 and 7, B–Y or
B signals to connectors 3 and 9, and R–Y or R
signals to connectors 5 and !¡.
When inputting YC signals, you can input Y signals to
connectors 1 and 7, and C signals to connectors 3
and 9. (Connectors 5 and !¡ are not used).
You can obtain loop-through output of the above
signals from connectors 2, 4, 6, 8, 0, and !™ ,
respectively. If you do not wish to use loop-through
output, attach 75-ohm terminators to connectors 2,
4, 6, 8, 0, and !™ .
