RE: CBUS Control Bus wiring topology

["Phil Harris" <phil@xxxxxxxxxxx>]

For my own install I used to use RJ45 patch panels with all the
terminals at
the back commoned together and then star out as much as possible but when
we
ran training courses we used to recommend creating rings as far as possible
(but leaving one end of the ring unconnected so it could be connected in
the
event of a break or cable fault)...
