Hello, i have printer encoder which i need to attach to Arduino Leonardo R3, but i don't know the values of +, GND, RX, TX. Can you help me? Printer: MFC-465CN (https://support.brother.com/g/b/spec.aspx?c=us&lang=en&prod=mfc465cn_all)

Here what i have:

What i need:


Thank you.


What does the encoder actually do, and why do you want to connect it to an Arduino?


I cannot find reference to a B30 7914 sensor but what makes you think it uses serial?

Looking at the images you poster I would guess that pin 1 (your numbering) is power, pin 2 is ground & pins 3/4 are the equivalent of A & B. I would expect them to be digital outputs that either pull high or low when the gate is interrupted.
Don't PM me for help as I will ignore it.


Ty all, btw Riva your guess is right. I forgott that i can use multimeter to find were is the gnd and +.
