Fanuc LR Mate 200iC I/O

Hi!
I am completly new in Fanuc robotics, and from the start I have troubles I am programing Fanuc LR Mate 200iC with R30iA controller. During cycle I need to recive one digital input signal an then send one. But whatever I've tried to do, I'm not able to do so.
I thought that, using the EE interface would be much easier. Sadly I cannot find any pinout scheme for 12 pin EE plug. I've tried to found which pin is RO, but when I'm switching manualy Robot Outputs nothings happens on the pins. So, maybe someone has got those pinouts? Or maybe someone could help me explaining what options should I have config to have that working?
Your knowlege would be very helpfull
Greetings

Thanks for replying!
But now I'm bit confused - when on my arm there is 12pin EE plug, there are only inputs there, and RO is only for steering air valves? Or I can somehow connect to those outputs?
