Terminators must be connected to the LONWORKS network. When setting up a network, connect one or two terminators
depending on the topology. The terminator consists of one resistor and two capacitors as illustrated below:
Bus Topology
Connect terminators to the both ends of the bus topology network.
Free Topology
Connect a terminator to any position on the free topology network.
