12. What is the coaxial digital adapter cable pinout on the X5 2nd gen?

A: Because the X3 2nd gen, X5 2nd gen, x5 3rd gen X7 and X7MKII use the same port for line output and coaxial digital output, we have bundled a different coaxial digital adapter cable for these players and these players are not compatible with the adapters from the X3 1st gen and X5.  

Specifically, please refer to the pinout diagram below;  those who would like to DIY their own adapter / cable, please study the pinout carefully, thank you.
