The D SERIES-RC4M is a remote control that provides source selection at single or multiple locations. The -RC4M is designed to directly connect to an RDL 4-channel switching module controlled by external momentary pushbuttons. The front panel of the -RC4M features four pushbuttons, each corresponding to one of four inputs. An LED adjacent to each button shows which source is selected. When an -RC4M is not being used, its display switches to a dim intensity to avoid being a visual distraction. The display returns to a bright intensity when a button is pushed.
