Please read the CC-Link Installation Manual carefully when wiring.
The following is a wiring example of a T-branch without repeater function.
- The cable color in this wiring diagram shows the cable color when using the recommended connector cable. When
wiring, check the instruction manual of the cable you actually use before wiring.
- Connect "Terminators" between DA-DB of the last unit on the CC-Link network.
- When this unit mounted on the both end of CC-Link network, please set the Dip switch SW4 to ON.（Refer to the
followiing Setting for Switch and Status LED indication (Remote part/Base part part）
・When installing with T-branch wiring, set the communication speed to 625 kbps or less.
- For wiring of external power unit 24V DC to FG, please return to wiring.
Connect "+" of power unit +24V DC to a terminal indicated [+24V] , "-" to [24G].
- Always use a constant voltage power supply such as a switching power supply.
(Use of a power supply with a ripple greater than the rated value, such as a full-wave rectifier power supply, may cause
malfunction.)
- Please set the cable length to consider the total length of the entire network according to CC-Link manual.
- When the Remote part and the Base part are not facing each other, no signal is sent from the Remote part, but there is
no problem in communication on the Base part.

*Always make changes to the DIP switches
with the power turned off.
If changed while energized, communication
is disabled and the status LED blinks at 0.5
second intervals.
*If the dip switch lid is opened, close it tightly
to prevent water from entering.
