Network Connection
The network connection (NET1 and NET2) is polarity insensitive. Therefore, either of the two twisted pair wires can
be connected to either of these network connections.
Network Topology Overview
The TP/FT-10 network is designed to support free topology wiring, and will accommodate bus, star, loop, or any
combination of these topologies. LPT-10 Transceiver-based devices and FT 3120 and FT 3150 Smart Transceiver-
based devices can be located at any point along the network wiring. This capability simplifies system installation and
makes it easy to add devices if the network need to be expanded. Figures 5.1 through 5.5 present five different
network topologies. The actual termination circuit will vary by application.
