BKM-129X Analog Component Input Adaptor

The BKM-129X Analog Component 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.

Functions

Expansion of analog RGB/component
inputs
Expansion of analog RGB/component inputs is
possible 1) .
Analog input and output signal
connectors
The BKM-129X is equipped with one input and one
output connectors for analog RGB/component signals.
EXT SYNC (external sync) signal
connectors
The BKM-129X is equipped with one input and one
output connectors for EXT SYNC signals.
Automatic termination (only terminals with
the mark)
The input connectors are terminated at 75 ohms inside,
when no cable is connected to the loop-through output
connectors. When a cable is connected to an output
connector, the 75-ohm termination is automatically
released.
Using the Input and Output
Connectors
For information about installing the BKM-129X in a video
monitor input option slot, see "Installing into Video
Monitors" on page 11(E).

Input of Y/P /P or RGB signals

When inputting Y/P /P or RGB signals, you can input
B R
Y or G signals to connector 1, P
(B–Y) or B signals
B
to connector 3 and P
(R–Y) or R signals to connector
R
5.
When the cable is connected to connectors 2, 4 and
6, the 75-ohm termination of connectors 1, 3 and
5 is automatically released, and you can obtain loop-
through output of the above signals from connectors
2, 4 and 6, respectively. Even if you do not wish to
use loop-through output, you need not attach the 75-
ohm termination to cconnectors 2, 4 and 6.
Input of EXT SYNC (external sync) signals
To operate the video monitor with the external sync
signals, input the standard signals from an external
sync generator, etc. to connector 7. You can obtain
the loop-through output from connector 8. To operate
video equipment with the video monitor by using the
same sync signal, connect the external input connector
of the video equipment to connector 8. Even if you
do not wish to use loop-through output, you need not
attach the 75-ohm termination to connector 8.

Assigning input signals to connectors
Before inputting signals to the BKM-129X, 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.
