Repeater Units
Terminating Resistance
Note
Note Set the same baud rate for all the nodes on the Network. Normal communica-
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.
1. Always turn OFF the PLC’s power before setting the terminating resistance
2. Turn ON the switch to connect terminating resistance at the nodes at both
3. The TER indicator will light when the terminating resistance switch is set
4. The switch is factory-set to OFF (terminating resistance not connected).
Repeater Units must be set as shown in the following table before starting
communications.
