Yes, you can use the Long Distance Sensor Bus (LDSBus) as a backbone connection, and use RJ45 splitters to form branches and sub-branches that cover the area within the 200m distance limit. This can help simplify the cabling needed compared to routing a single cable around every room in turn.

The total distance to the furthest LDSU can be up to 200m. This is the total distance (including the RJ45 cabling and the RJ11 connection from the Quad T-Junction to the furthest LDSU).

As with a linear LDSBus topology, only one LDSU on the bus should have termination enabled. Termination must be enabled on the LDSU which is furthest from the IoTPortal Gateway.
