The LDSBus Quad T-Junction connects LDSBus Devices (Sensors/Actuators) to the LDSBus. It serves as a data and power interface between the LDSBus host and the LDSBus devices.

Each LDSBus Quad T-Junction can connect up to four LDSBus Devices.

Additional LDSBus Quad T-Junctions may be daisy chained to add more LDSBus devices to the bus.
