HI I can't see why my hardware always lights the LED of the opposite Button. Pushing Mute 1 Lights up Mute LED 8. I checked my Cabeling twice and can't imagine that i did something wrong. I will ad some Pictures of my Testboards to improve that. As you see. The IDC connectors are al the same on the DIN/DOUT side. And on my Testboard i wired the colors to the same Button as well as the LED. who can tell me why this turns out to be crossover? Best regards novski
