Meicheng Professional Video Scaler CSC-1600HD has two sets of output connectors for you to choose from the HD-15 D-sub and the RGBHV BNC jacks. Only one of the two output terminals has signal running on it at one time.

When one output terminal is selected the other terminal will have no output signal. You can use the two buttons (HD-15 and BNC) on the remote control to choose your desired output or you could go to the "Output terminal" tool bar under the ON Screen Menu to choose the terminal you want.

The 5 BNC jacks are shared by RGBHV output and YPbPr output.

When 480P or 576P output resolution is selected the three BNC jacks from the most left to the center will carry Pr,Y and Pb correspondingly. In this case only three plugs are needed to connect the YPrPb output to the destination TV/Monitor.
