I have sucessfully added the J1sysE131 dll for vixen 2.5 to my system. And the particulars of what I'm trying to do are thus:
I have an existing technology already set up. (Youtube: http://youtu.be/Rfu_x8sSPUo if you are curious.) Basically I already have LED controllers and drivers of my own design. What I want to do is teach it to understand DMX when it arrives over the ethernet, and just run a GIGO mode in that case, but my existing algorithms when Vixen isn't displaying anything. This gives me both scripted shows and algoritmic shows both.
But when I try to tell the J1sysE131 dll to use a unicast address instead of multicast, it gives me a possible runtime error. And when the test show runs, it says no packets went out and nothing happens. It doesn't happen quite fast in fact. I suspect I'm doing something incorrectly, but I rt clicked the destination and it took the IP of the target board. It just doesn't run with it.
188.8.131.52 version if that matters.
