Ring Topology
The ring topology is a permutation of the daisy chain configuration. In
the ring topology, the end node's transmitter is connected to the
master node's receiver. This topology can include center nodes; the
only difference between the center and end nodes is their physical
location. You can use a maximum of 10 nodes, including the master
node, with this topology.

Master Node
The advantages to using the ring topology are:
· The topology does not require a hub.
· Data moving downstream can be modified from node to node.
· Data can be passed back to the master.
The disadvantage to using the ring topology are:
· A single node failure brings down the entire link.
· It is more difficult to troubleshoot.
· Axis and buffered data cannot be passed through without
For more information on the configurations available in the ring
topology, see page 4-13.
