Signal Wiring – PCB to RJ-45 Jack for Nextion Display
The Nextion HMI is connected to the connection box via an RJ-45
connector. Using piece of CAT 5 (or greater) wire, 4 feet long, make the
connections to the HMI’s connector (supplied by the vendor) as shown to
the right.
Put a
¾
” long piece of shrink file onto each one of the Nextion wires
before connecting it to the CAT 5 wires.
Connect the CAT 5 wire to the Nextion wires using a lineman’s splice
(AKA, the Western Union splice, and shown to the right), and then solder
the two together.
Heat the shrink file tubing around the joint to insulate it from the other things it could touch.
