video monitor, it provides video input and output connectors
for the monitor and a decoder for analog composite PAL-M
signals.
Functions
Decoder for analog composite PAL-M
signals
The BKM-126M is equipped with decoders for analog
composite PAL-M signals.
Analog input and output signal connectors
The BKM-126M is equipped with two input and two output
connectors for analog signals.
Automatic termination (only terminals with
the mark)
The input connectors are terminated at 75 ohms inside, when

Input of analog composite PAL-M signals
You can input analog composite PAL-M signals to connectors
1and 3. When the cable is connected to connectors 2and
4, the 75-ohm termination of connectors 1and 3is
automatically released and you can obtain the loop-through
output from connectors 2and 4. Even if you do not wish to
use loop-through output, you need not attach the 75-ohm
termination to connectors 2and 4.
