I am quite a newbie to arduino and currently stuck with an encoder. I have a BLDC geared motor with encoder, all I want to do is to get values from the encoder. There are 6 wires, out A, out B, out Z, +V, 0V, F.G How should I wire those six of them correctly?

Encoder specification says 5VDC is ok to power it, and I want to make a circuit to power encoder using Arduino Mega board.
