● When routing the signal cable, ensure that it is separate from the power cable
and away from interfering sources to prevent communication from being
affected.
● The protection layer of the cable is in the connector. Cut off surplus core wires
from the protection layer. Ensure that the core wires are completely inserted
into the cable holes, and that the cable is securely connected.
