I can confirm that the function info is not in the dll. I try to use the function in the dll : configure seems work, ChannelSet I don't sure. I succeed to use the uDMX.exe to configure channel and values. So, If it's feasible to call an exe, it could be functionnal, but I don't know if it is a good solution. I think that Connected function is not usefull too. So, could you please delete the connected function so that I could test (I think for a last time) this interface ? Why it does not work with EE, I don't know.
