Burl, I don't recommend the wired interface anymore. The radio version works much better. The wired interface, of course because it is wired, is connected to only one TIU and it will communicate with only one TIU so there is no Super TIU mode possible.
I will try to help you out. Contact me at markd@silogic.com and we'll see if we can figure out what is going on.
