Setting Terminating Resistance
Turn the built-in terminating resistance ON or OFF using the terminating resistance switch
(slide switch). Terminating resistance is required at the both ends of a wired network to ab-
sorb unnecessary signals and reduce the noise. The Controller Link Support Board has built-
in terminating resistance, which can be connected simply by setting the slide switch to ON.
Set the switch to ON to connect the terminating resistance at both end nodes in wired net-
works and set the switch to OFF at all other nodes.
