The Free Topology Transceiver (FTT) system
is designed to support free topology wiring
and accommodates bus, star, loop or any
combination of these topologies. The FTT
transceiver located on the VLT LonWorks
option card provides I/O functions. Flexible
wiring capability simplifies system installation
and makes it easy to add nodes for system
expansion. The figures below represent five
