BKM-127W NTSC/PAL Input Adaptor

The BKM-127W NTSC/PAL Input Adaptor is a video
signal input adaptor for Sony video monitors. When
installed in an input option slot of the video monitor, it
provides video input and output connectors for the
monitor and a decoder for analog composite NTSC
and PAL signals.
For the monitors in which the BKM-127W can be installed,
see the chart on page 1 (E).

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 15(E).
For installation in the LMD series monitor, refer to the
operating instructions of the monitor.

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.
