3. 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:

Configure the remote LonWorks devices according to manufacturer’s instructions.
