The following Quick Tip video covers the necessary hardware and software setup requirements to connect a Mitsubishi GOT (Human Machine Interface) touch terminal to a Mitsubishi PLC (Programmable Logic Controller). Please note that a crossover cable is necessary for direct connections.

(For low speed the data lines may not be twisted.) The signals on these two wires are referenced to the (third) GND wire.
