The maximum transmission distance will also change according to the setting.
tion cannot be performed unless the same baud rate is set for all the nodes.
Turn ON the terminating resistance using the switch on the bottom of the Unit
for the Units of both ends of the Network. The terminating resistance is
required at both ends of a Network to absorb unnecessary signals and reduce
noise.
The Controller Link Unit has built-in terminating resistance, which can be con-
nected simply by turning ON the slide switch.
