Using the Input and Output
Connectors
For information about installing the BKM-48X in a video
monitor input option slot, see “Installing into Video
Monitors” (page 7 (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
,
3
,
5
,
7
,
9
, and
!¡
. You can obtain loop-
through output of those signals from connectors
2
,
4
,
6
,
8
,
0
, and
!™
, respectively. If you do not
wish to use loop-through output, attach 75-ohm
terminators to connectors
2
,
4
,
6
,
8
,
0
, and
!™
.
Input of Y/R–Y/B–Y, RGB, or YC signals
When inputting Y/R–Y/B–Y or RGB signals, you can
input Y or G signals to connectors
1
and
7
, B–Y or
B signals to connectors
3
and
9
, and R–Y or R
signals to connectors
5
and
!¡
.
When inputting YC signals, you can input Y signals to
connectors
1
and
7
, and C signals to connectors
3
and
9
. (Connectors
5
and
!¡
are not used).
You can obtain loop-through output of the above signals

Assigning Input Signals to Connectors
Before inputting signals to the BKM-48X, 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
CONFIGURATION menu of your video monitor.
For information about using the INPUT CONFIGURATION
menu, refer to the manual of your video monitor.
Combination of Multiple
Adaptors
You can configure an input and output connector panel
by installing any combination of adaptors in the input
option slots on the rear panel of the video monitor.
By combining adaptors of different types, you gain
access to a wider range of input signals than would be
possible with a single adaptor type. The input signals
made available by different combinations of adaptor
types are shown in the table on the next page.
The number of input option slots varies with video
monitors, and to specify signal types for each input
connector, use the on-screen INPUT
CONFIGURATION menu of your video monitor.
For information about the input option slots and using the
INPUT CONFIGURATION menu, refer to the manual of
your video monitor.
Internal Connections between Decoders
When you install a decoder adaptor (BKM-20D/21D/
24N/25P/26M/27T), it is connected to the other
adaptors installed in your video monitor’s input option
slots over an internal bus. Therefore, if you install a
decoder adaptor for a given signal, you can decode that
signal even when it is input to another adaptor.
