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.
