Analog sensors connection
Connect the analog sensor by a supplied RJ-11 (6P4C) cable to any analog port "A1 .. A8" or "Sensor" port. The determination of the sensor type and connection will occur automatically.
If strong electromagnetic interference is present, we recommend using 3-pair cable CAN FTP for sensor connection!
6P4C RJ11 cable wiring / pinouts
1- Yellow, 2- Green, 3- Red, 4 - Black
Colors are true for this telephone cable. Both ends match the colors and pinouts (identical).
Please refer to the RJ connectors comparison table:
Daisy chain connection
Some of the analog sensors can be connected in a daisy chain. Please refer to the article "Chain connection of analog sensors".
