BKM-127W NTSC/PAL Input Adaptor
Analog composite signals
The BKM-127W NTSC/PAL 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 analog composite NTSC and PAL signals.
Functions
Decoder for analog composite NTSC/PAL
signals
The BKM-127W is equipped with decoders for analog
composite NTSC and PAL signals.
Analog input and output signal
connectors
The BKM-127W is equipped with two input and two
output connectors for analog signals and one input and
one output connectors for YC 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-127W in a video
monitor input option slot, see “Installing into Video
Monitors” on page 11(E).
Configuration of input/output connectors
and signals that may be input
The configuration of the input and output connectors
and the signals that may be input are shown below.
Input of analog composite signals
You can input analog composite signals to connectors
1 and 3. When the cable is connected to connectors
2 and 4, the 75-ohm termination of connectors 1
and 3 is automatically released and you can obtain
the loop-through output from connectors 2 and 4.
Even if you do not wish to use loop-through output,
you need not attach the 75-ohm termination to
connectors 2 and 4.
Input of YC signals
You can input YC signals to connector 5 and obtain
loop-through output of the signals from connector 6.
Even if you do not wish to use loop-through output,
you need not attach the 75-ohm termination to
connector 6.

Assigning input signals to connectors
Before inputting signals to the BKM-127W, 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.
