Thanks Curtis for the info. I emailed Clark about this because the diagram on the website didn't match the silk screening on the TK that I have as far as "J2" goes. Also, there was some confusion as to which pins where to be jumped in order to put the board into programming mode which was ultimately the problem i was having. I simply could not get the board into the programming mode no matter what I seemed to have tried. I used one of the 3-pin cables to jump pins 2 and 3 and it worked like a charm so I'm all set now. He also modified the instructions on the website as well so it should be even more helpful for newbie TK35 owners like myself.

Thanks again,

Dave
