Input of serial digital signals
You can input serial digital signals to connectors
1
,
3
, and
5
. You can obtain active loop-through output
of those signals from connectors
2
,
4
, and
6
,
respectively.
You need not attach 75-ohm terminations to
connectors
2
,
4
, and
6
.
Input of analog composite signals
You can input analog composite signals to connectors
7
,
9
, and
!¡
. You can obtain loop-through output of
those signals from connectors
8
,
0
, and
!™
,
respectively. If you do not wish to use loop-through
output, attach 75-ohm terminators to connectors
8
,
0
, and
!™
.
Input of Y/R–Y/B–Y or RGB signals
You can input a Y or G signal to connector
7
, an B–Y
or B signal to connector
9
, and a R–Y or R signal to
connector
!¡
. You can obtain loop-through output of
those signals from connectors
8
,
0
, and
!™
,
respectively. If you do not wish to use loop-through
output, attach 75-ohm terminators to connectors
8
,
0
, and
!™
.
Assigning Input Signals to Connectors
Before inputting signals to the BKM-21D, 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.
