RE: xAP - The Proposed Architecture Explained...

[ian.bird@xxxxxxx]

Hi Tony

In an RS485 network the term multidrop and daisy chain go hand in hand.
Think of a single piece of two strand cable running round the various
rooms
of the house. When you want to add a device to it you just crimp the
connections to the main wires. Note there are no T junctions and as small
as
possible a neck to the device. Add on loads of devices and you have
multi
drop. The devices at each end have termination resistors on to stop
signal
reflections but that is getting techy.
