3.1 General
3.2 Physical media and wiring
LONWORKS networks can be implemented on many different physical media. Drive OPT-C4
option board is equipped with an FT-X1 transceiver supporting the Free Topology transformer
coupled network, which allows the network wire to be connected as bus, star, loop or combi-
nation of these. This media reaches a communication speed of 78kBits/s. The FT-X1 transceiv-
er is compatible with Echelon's LPT-10 Link Power Transceiver, and these transceivers can
communicate with each other on a single twisted pair cable.
Figure 1. Doubly terminated bus topology
The doubly terminated bus topology is recommended to be used. However, also singly termi-
ated, star or loop topologies can be used with OPT-C4 option board.
Up to 64 FTT-10 transceiver nodes are allowed per network segment, the individual segments
can be connected together by a router. See Table 3
for possible cable types and cable lengths
for FTT-10. Even if unshielded cable types are possible to be used with this type of transceiver,
it is still highly recommended to use only shielded cables with frequency converters . At-
tention should be paid to proper grounding of the shield to ensure bus operation. Grounding of
the shield should be done at both ends of the cable.
