*1 These are NON SAFETY-RELATED components.
 Optical synchronization system
 Transmitter: 5-core cable, Receiver: 5-core cable
(1) PNP output cable
(2) NPN output cable
 One-line system
• The series connection cable must be used to connect the transmitter and receiver.
• The unit connection cable is not needed for the transmitter.
 Transmitter: Series connection cable, Receiver: 5-core cable
(1) PNP output cable
(2) NPN output cable
 Wire synchronization system
 Transmitter: 11-core cable, Receiver: 11-core cable, EDM input used
(1) PNP output cable
(2) NPN output cable
Indicators
 Function indicators
 7-segment display
 Upon power-up
NOTICE If any input or output wires remain open (completely disconnected), they must be capped.
