I believe what you are referring to is a polarity issue... what you have to do with that particular set up is.. git a PC cord that has a two trong plug on one end, and a card that has a reciever for that plug, that will fit into the pc socket on the strobe.. It will work one way, but not the other way..
The thing that's nice about those cords, is that they often come in packaging that you can easily "open" at the story......(no,...I don't want you stealing it)..

I believe that will.. and it will also cause you to use twist ties to keep all that darn cord out of your way..
The same prob,es happened on all of my previous Canon bodies for some goofy reason... I always had to dink around with the sync cord thingy with my DC powered Norman strobes,....and finally,.......Canon fixed that problem!! (another reason for getting the 20D over the 10D, or Rebel cameras..) [img]/ubbthreads/images/graemlins/smile.gif[/img]
That should work from what you are describing..
