He has a 102, and that cable is only for 100, as in going all the way from the 100 to the dvi in one shot with no other adapters and no option for supporting 102 or 200.
That actual cable in the pic is one I made, and is correct, but later I came up with the 3-part cable that doesn't need any loose-wire twsists, thanks actually to you saying how a male-male striaght through gender-changer actually solves the "twist" problem for 102/200. Apparently Greg sold out of all the ones I made and tried to make new ones himself. A picture was posted by someone else with the same problem that has 2 male boxed headers with 40 individual wires soldered and individually heat-shrinked. I naver made a cable like that. The cables I made for Greg included one of the 3 pieces was a part with 2 male headers back to back, but the gap is filled with hot-glue so you can't see that the pins are soldered directly to each other, no criss/crossing. But a multimeter would still show it and I didn't exactly try to keep it secret with directions and pictures. Both the directions and pictures could be clearer thoiugh. I should draw something with cad renders or something so it's easier to see and get it right.
