Everyone.

Please allow me if my understanding is incorrect. To my best knowledge, FTDI cable (TTL-232R-RPi)'s yellow wire is input signal toward PC. It is designed to connect to RPi's TXD pin. And orange wire is output signal from PC. So my understanding is, right connection is as following. 

 Board     Wire       Function
 Pin 1.....Black......Ground
 Pin 4.....Orange.....PC (TXD) to BBB (RXD)
 Pin 5.....Yellow.....BBB (TXD) to PC (RXD)

Confirmed on the BBB schematics and DMM, and also experimented by myself.

Regards, Atsushi Yokoyama

I believe it's correct. The description on the page is taken directly from the Datasheet: DS_TTL-232R_RPi.pdf
