This cable is used to connect two DataTalkers back to back. The cable is asymmetrical and allows one of the DataTalkers to provide clocking to the TxC and RxC pins of the other DataTalker. Make sure the composite link configurations of the DataTalkers have one of them set for an internal clock and the other for an external clock.
