Figure 2. Typical Wiring Topologies Supported by FT Smart Transceivers
This design has many advantages:
• The installer is free to select the method of wiring that best suits the installation,
reducing the need for advanced planning and allowing last minute changes at the
installation site.
• If installers have been trained to use one style of wiring for all installations, free
topology technology can be introduced without requiring retraining.
• Retrofit installations with existing wiring plants can be accommodated with minimal,
if any, rewiring. This capability ensures that FT Smart Transceiver technology can
be adapted to both old and new projects.
• Free topology permits FT Smart Transceiver or Neuron Chip systems to be expanded
in the future by simply tapping into the existing wiring where it is most convenient
to do so. This reduces the time and expense of system expansion, and from the
customer's perspective, keeps down the life-cycle cost of the free topology network.
