System Setup Examples
Bus Topology
Nodes are connected to one trunk line. The trunk line
can be extended up to 1,400 meters.
Terminators are needed at both ends of the network.
Free Topology
The network can also be connected in star, loop, bus,
and combination of these configurations. The network
can be expanded and modified flexibly.
One terminator is needed at any place on the network.
Quantity of Nodes (FTT-10A Transceiver Nodes)
A maximum of 64 nodes can be connected to one
channel. When connecting more than 64 nodes, a
router or repeater is needed.
One router is regarded as one node. Consequently,
when using one router, the maximum number of nodes
connected to one channel will reduce to 63.
