Because the video signal the video distributor only routed one direction from Bus_IN Bus_OUT, all devices which emit video signal must connected Bus_IN via the Gira 2-wire bus. video multiplexer can bring the video signals from three cameras together. there are more than three sections system, the following rules apply: - The terminating element installed the three sections with the most devices with BUS_IN/BUS_OUT terminal. Terminating element A terminating element included with delivery the video distributor. The following rules apply the use the terminating element: - terminating element required system operated with more than ten devices with BUS_IN/BUS_OUT terminal (e. 1224 00 Technical data Ambient temperature: -25°C +70°C Port: Screw terminals Dimensions D): 27mm Installation: surface-mounted sur- face-mounted junction box - flush-mounted deep flush- mounted device box - on top-hat rail using included DRA adapter Device description The video multiplexer bundles the video signal door stations, DCS-camera-gateways and DCS-IP-gateways. - The terminating element connected the BUS terminals parallel to the 2-wire bus..

Using two video multiplexers, the video signals from five devices can brought together.
