what is the DB9 connector pin-out for the 778475-01 USB-422 module?

what is the DB9 connector pin-out for the 778475-01 USB-422 module?

I can not locate the pin-out for the USB-485, 1-Port USB to RS-485 Converter in the users manuals or the knowledgebase. I need to know the pin designations for the DB9 connector and what pin #'s are RX+, RX-, TX+, TX-, etc.
 
Thanks,
Ant
