What pin is the 5 volt power supplied to on the VC70?

From the beta slides:

2 RS232 ports: x1 DB9 with 5V out
x1 DB15 (shared with CAN-bus)

I measured the power on Pins 4 and 5 on the VC70 Com1, but the cable recommended (CBA-R36-C09ZAR) is powered on Pin 9 with GND on Pin 5.  If we make an adapter will that work?  Can you provide the full pin out for Com1 so we know how to make an adapter please?
