The multi-drop configuration varies in that each expander uses the same
communication channel as it wires onto the next expander, with all expanders
using the same input channel. See multi-drop configuration in the second figure.
In the case of a X-BUS break, all expanders and detectors up to the fault continues
to be supervised. A short in the cable renders all expanders disabled.
