RAS-2 and 2 x KRG3 on RCB3?

[Meltdown]

Is it true that the accelerator RAS-2 needs 2 analog sensor inputs on the RCB3?
So you can't use two KRG-3 gyros along with the RAS-2 because you need 4 anolog inputs and you only got 3 of them on the RCB3?
Am i missing something here?

in the SP1 pdf kondo show the use of 2 gyros and the RAS-2 - they just use one of the outputs (X axis or Y axis) to detect a fall - since it's unlikely that he'll fall on his side you only ned 1 axis with this sensor

Thanks a lot for the info!
I thought so but i needed some conformation.
