PRODUCT OVERVIEW

2.3 Topologies

There are various topologies for the GT200 VME card. These topologies should cover
most customer applications, though if another topology is desired contact Curtiss-Wright
Controls, Inc. Technical Support to see if it is possible. The topologies are:

Non-redundant ring
Redundant ring
Point-to-Point
Daisy Chain
Monitoring
Switch ring
Redundant switch ring

2.3.1 Non-Redundant Ring

This is the simplest of the topologies, with a single transmit/receive connection per node.
Any data written to one node is broadcast to all nodes. A break in one node of fiber
caused the ring to be broken. This topology would be used in a system where a failure in
the ring is not critical.

2.3.2 Redundant Ring

This topology is the same as a non-redundant ring; only a second ring is added using the
second transceiver to create a ring with data flowing in the opposite direction. A failure
in one of the rings does not prevent data from flowing to all the nodes. This topology
would be used in critical systems where a break in the ring cannot be tolerated.
