  What is free topology?

  Free-topology technology enables wiring in any configuration to suit the needs of the application — star, bus/drop, ring, or mixed
• Lowers cost by reducing the time and expense of system installation; Also simplifies network expansion by eliminating restrictions on wire routing, splicing, and node placement
• Higher field reliability because wires can be crossed from one device to the next without causing errors; Proven reliable in tens of millions of devices for mission critical control applications
• Well isolated for reliable communications; 78kbps up to distances of 500 meters (free topology) or up to 2,700 meters using double terminated bus (worst case)
• Ideal for multiple products within building automation systems: HVAC, access, lighting, elevators, and many others; Standards listings include UL, CSA, TÜV recognized component
