Wiring Definitions

Signal	Definition
⊥	Power cord ground wire
B (left)	Data Cable B (Pair 1), Incoming Line
A (left)	Data Line A (Pair 1), Incoming Line
(-)	0V
(+)	10V…30V
B (right)	Data Cable B (Pair 2), Output Cable
A (right)	Data Line A (Pair 2), Outgoing Cable
(-)	0V
(+)	10V…30V
The power supply only needs to be connected once (regardless of which terminal group is used); when the terminal resistor is engaged, the BUS OUT is disconnected.

LED indicator

LED red	LED green	Status Information/Possible Causes
暗	暗	No power supply
亮	亮	The rotary encoder is ready for operation but has not yet received voltage-based configuration data. Possible causes: incorrect address settings or improper bus connections.
亮	闪	Parameter allocation or configuration error: The length of configuration or parameter allocation data received by the rotary encoder is likely incorrect or data is inconsistent; possible cause: e.g., total resolution set too high.
闪	亮	The rotary encoder is ready for operation but has not been accessed by the master station (e.g., due to an incorrect address).
亮	暗	The rotary encoder has not received any data within a certain period of time (approximately 40 seconds) (the data line may be disconnected).
暗	亮	Data exchange operates in normal mode.
暗	闪	Data exchange operates in debug mode.
