INTRODUCTION

The Free Topology Transceiver (FTT) supports polarity  
insensitive, free topology wiring. This frees the system  
installer from wiring using a specific bus topology. T-tap, star,  
loop, and mixed wiring topologies are all supported by this  
architecture. Free topology wiring reduces the time and  
expense of system installation by allowing the wiring to be  
installed in the most expeditious manner. It also simplifies  
network expansion by eliminating restrictions on wire routing,  
splicing, and device placement.

A FTT network may comprise multiple segments (LONWORKS  
Bus sections containing from one to sixty devices, each  
device having a Neuron® ID to validate) separated by  
physical layer repeaters or routers.

FTT networks are very flexible and convenient to install and  
maintain, but it is imperative to carefully plan the network  
layout and create and maintain accurate documentation. This  
will aid in compliance verification and future expansion of the  
FTT network. This will also minimize unknown or inaccurate  
wire run lengths, node-to-node (device-to-device) distances,  
node counts, total wire length, inaccurate repeater/router  
locations, and misplaced or missing terminations.

APPLICATIONS  
Free topology architecture allows the user to wire the control  
devices with virtually no topology restrictions.

Unlike bus wiring designs, the FTT system uses a free  
topology wiring scheme that supports T-tap, star, loop, mixed,  
and/or daisy-chain (see Fig. 1). This design has many  
advantages. First, 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. Second, if installers have been trained to use  
one style of wiring for all installations, free topology

technology can be introduced without requiring retraining.  
Third, retrofit installations with existing wiring plans can be  
accommodated with minimal, if any, rewiring. This capability  
ensures that FTT technology can be adapted to both old and  
new projects, widening the potential market for FTT based  
products. Finally, free topology allows FTT systems easy  
future expansion by 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 customers’ perspective,  
keeps down the life cycle cost of the free topology network.

Cable Termination  
Daisy-Chain (Double Termination)  
Network Segment  
The FTT network segment requires termination for proper  
data transmission performance. Use a 209541B FTT  
termination module. Free topology (singly terminated)  
segments use the yellow and brown wires. Daisy-chain  
(doubly terminated) segments use the orange and brown  
wires. See Fig. 4.  
In a daisy-chain free topology segment (doubly terminated)  
two terminations are required, one at each end of the FTT  
daisy-chained network segment. See Fig. 6 and 7.
