Title: ProRace buttons / encoders
Post by: vicsalt on February 02, 2014, 05:25:21 pm

I've tried for 2 days and finally given up, I have a Pro Race dash with 2 encoders connected, they are connected in following manor

encoder - 3 terminals we will call A, B, C.  B = Middle pin

ENC 1 - middle terminal "B" to Pin 1
ENC 2 - middle terminal "B" to Pin 2

ENC 1 -  Terminal "A" has Diode then connects to ENC 2 Terminal "A" (no diode)
ENC 1 -  Terminal "C" has Diode then connects to ENC 2 Terminal "C" (no diode)

All Works fine
I want to connect 2 more encoders & 5 push buttons, I have tried every option but cant get them to work

Questions
Should ENC 2 have diodes ?
Do all PB have to have a diode ?

Hello.
if you have connected rotary encoders, you need to use diodes for all the rotary encoders and push buttons.

have you considered the Button adapter?

it makes connections much easier because it has all the diodes soldered on the pcb.
