BKM-128WX Analog Input Adaptor

The BKM-128WX Analog Input Adaptor is a video
signal input adaptor for Sony LCD monitors.
When installed in the optional input slot of a monitor,
it provides video input and output connectors for the
monitor.
For the monitors in which the BKM-128WX can be installed,
see the chart on page 1 (E).
Note
When you install the BKM-128WX into the LMD-
151MD or LMD-181MD monitor, use the monitor
whose serial number is given in the table below. If
installing the BKM-128WX into the monitor with an
earlier serial number, contact Sony Service.
Model Serial number
LMD-151MD 2000461 or later
LMD-181MD 2000801 or later

Functions

Analog composite/YC input and output
signal connectors
The BKM-128WX is equipped with one input and one
output connectors for analog signals and one input and
one output connectors for YC signals.
The adaptor is equipped with a decoder for analog
composite NTSC and PAL signals.
Analog RGB/component and external sync
input and output signal connectors
The BKM-128WX is equipped with one input and one
output connectors for analog RGB/component signals
and one input and one output connectors for EXT
SYNC signals.
Automatic termination (only terminals with
the mark)
Aperture enhance function
As the resolusion is converted when monitoring an
NTSC/PAL signal on an LCD monitor, the picture
outline becomes softer. The BKM-128WX enhances
the picture outline to provide a sharper picture. The
function is related with the setting of the menu on the
LMD-181MD/151MD LCD monitors.
The function does not work for the RGB/component
input signals.
Trap filter incorporated
A trap filter incorporated into the BKM-128WX
enables reducing noise produced when signals with a
specific frequency range are displayed on an LCD
monitor.
Using the Input and Output
Connectors
For how to install the BKM-128WX in the optional input
slot on a monitor, refer to the operating instructions of the
monitor in which the adaptor is installed.

Input of analog composite and YC signals
You can input analog composite signals to connector
1 and YC singnals to connector 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.

and 0, the 75-ohm termination of connectors 5, 7
and 9 is automatically released, and you can obtain
loop-through output of the above signals from
connectors 6, 8 and 0, respectively. Even if you do
not wish to use loop-through output, you need not
attach the 75-ohm termination to cconnectors 6, 8
and 0.
