HARDWARE CONNECTIONS
LonWorks devices are available with several different physical interfaces. The screw plug supplied with the FieldServer
LonWorks interface will connect the FieldServer to the FTT-10 network. The 9 pin D-connector can also be used to connect to
the network (FS-B4011 only). The 2-wire twisted-pair connection to the network is polarity insensitive. The FTT-10 network is
a free topology network which supports star, loop and/or bus wiring connections. Please refer to the FTT-10A Free Topology
Transceiver User’s Guide from Echelon Corporation for recommended wiring practices if necessary. The connection diagram
below shows how the FieldServer FS-B2011, FS-B30 and FS-B4011 are connected to a LonWorks network:
