Unit Vent

LonWorks network points are spawned within the device as a result of downloading graphical control programs.
The Unit Vent controller speaks the LonWorks Protocol as described by Echelon Protocol Specification. Since the
controller is custom-programmable it does not conform to LonMark certification. Further details on the LonWorks
supported implementation are described below.

The FT 3120 Free Topology Smart Transceiver is fully compatible with the TP/FT-10 channel and can
communicate with devices using Echelon's FTT-10A Free Topology Transceiver. The free topology transceiver
supports polarity insensitive cabling using a star bus, daisy-chain, loop, or combination topology.
