ABB-Welcome Video Distributor

As a video signal branching device in the internal bus, video distributors should be used when star connection is needed for the apartments in the building part and for the gateways in the common part. For the audio system, the video distributor is not needed in the building part and the common part.

Each video distributor can connect up to 4 apartments or 4 lines in the building part and 4 gateways in the common part. The cascaded connection is also possible. The impact of the distance can be reviewed from the distance calculation.

When video distributor is used in the common part, the total distance of all the lines branched by the video distributor under one system controller should be less than 800 meters. Auxiliary power supply can be used to split the whole distance into several sections, which can ensure each section meet the 800 meters distance limit with one system controller. The distance constraint from different cables should
