When the termination switch is set to BUS, 100Ω 1/8W termination resistance is connected between communication
terminals A and B.
For a free topology network connection, terminate one module on the network. When the termination switch is set to
FT, 50Ω 1/8W termination resistance is connected between communication terminals A and B.
The following table describes the type and feature of the termination resistance for each switch position.
