Definition of M12 8-Pin connector
Connect the cable inside the box to the power supply and communication system. The unused color cables should be covered or protected to avoid electric leakage or short circuit.
Before removing the top housing of the device and wiring, the device should be powered off and the M12 8-pin cable should be removed.
Due to space constraints, the sticker on the side of the device and subsequent illustrations only use cable contact definitions.
Please see below images to know where each cable is connected.

Wiring Suggestions
It is generally recommended to use a 24awg twisted pair cable with grounded shielding. The RS485 network must be designed as one line with multiple drops, not as a star or ring topology.
When the connection is long, please use the terminal resistance on the master and the farthest end of the line. It is generally recommended to use a 120Ω terminating resistor. For the actual value, please refer to the wire specifications.
If the signal is unstable, please choose a point on the line to use a bias resistor.
The 8-core cable is shipped with the device, if used in RS485 communication, please trim the length, try to use a short wire to reduce noise interference. Connect the shielding net to the main communication wire shielding and then ground it.
When there is a lot of signal interference, the software may need to do multiple inquiries to get a valid response.
Device Contact Definitions
Due to space constraints, the sticker on the side of the device only uses cable contact definitions.
The number of the device contact and the cable contact is mirrored and symmetrical.
