If the settings are correct which they seems to be it's only the cables and the red straps which could be the problem. Are you sure you have counted the pins from the right direction when making the cables ? If you count from wrong direction they work when connecting togehter but not via the RRC.s. If you make the Radio-RRC available over internet, we can test to connect from here to determine if the radio-end is correct, then you know where to start to look.
