The video distributor cascadable. video multiplexer can
bring the video signals from three cameras together. 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. 1224 00
