OPENNET CONTROLLER USER’S MANUAL 26-7

Terminator

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.

R 105Ω, 1%, 1/8W

C1 and C2 100 µF, ≥50V (note the polarity)

R 52.3Ω, 1%, 1/8W

C1 and C2 100 µF, ≥50V (note the polarity)
