BKM-20D SDI 4:2:2 Decoder Adaptor The BKM-20D SDI 4:2:2 Decoder Adaptor is a video signal input adaptor for BVM-Series video monitors. When installed in an input option slot on the rear panel of the video monitor, it provides video input and output connectors for the monitor and a decoder for serial digital component signals. 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. Functions Decoder for Serial Digital Component Signals The BKM-20D is equipped with a decoder for serial digital component (525/625) signals. If decoder adaptors for analog composite signals are installed in other input option slots, you can use them to decode analog composite signals input to the BKM-20D. Serial Digital and Analog Input and Output Signal Connectors The BKM-20D is equipped with three input and three output connectors for serial digital signals, as well as three input and three output connectors for analog signals. Using the analog signal input connectors, you can input one Y/R-Y/B-Y or one RGB signal, or three analog composite signals. The types of analog composite signals that may be input vary depending on the input adaptors installed in other input option slots (see page 20(E)). Using the Input and Output Connectors For information about installing the BKM-20D in a video monitor input option slot, see "Installing into Video Monitors" (page 21(E)). Note on using the BKM-20D When installing adaptors, moving the analog input connectors board, or fitting a cover plate over an unused slot, always fit the BKM-20D as the last step of the operation. If a BKM-20D is already installed, remove it temporarily while carrying out the other operations, then reinstall it last (see page 22(E)).

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 !™ . 3(E)
