I finally got around to assembling my RPM E1.31->DMX dongle I purchased last year (and the BOM earlier this year). Since I had it built, of course I wanted to test it. I kept putting off buying a PropPlug, and now I'm kinda glad I did. I wasn't sure if I'd be able to use something else I have from my various tinkering escapades, and I was able to figure something out. I'm posting this in case somebody else is in a similar dilemma.
From my initial reading on a PropPlug it showed that the PropPlug operates at 3.3V and there is a potential for damage if you use 5V. I only have a 5V ftdi cable so I couldn't use that. I grabbed my FTDI Friend and flipped it over. Much to my delight, look what I saw!
I was able to cut the trace for the 5V default, and it was already setup for 3.3V logic.
I was able to take 4 jumper wires as shown (I used different colors so I could match up the pictures for future reference):
