Terminating element A terminating element included with delivery the video distributor. A maximum three terminating elements may installed one sys- tem. - The terminating element connected the BUS terminals parallel to the 2-wire bus. Connection terminals: Bus_IN Connection for the incoming video signal from door stations with video function, DCS camera gateways DCS gateways. 1226 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 distributor distributes the video signal the door stations, DCS-camera-gateways, and DCS-IP-gateways the home stations. 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. Using two video multiplexers, the video signals from five devices can brought together. 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. 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.
