BKM-21D SDI Multi Decoder Adaptor 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.
