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

I cannot 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.

I found a post identical to this one (link below) but the links given as responses are no longer active as the question was posted 13 years ago.

Thanks in advance for all your help
