New Project with Mesa 7I96 and THCAD-05
This is not normal, and suggests a grounding issue or similar
If its connected as I suggested you should read 0V at the 7I96 input until you get the ARC/OK signal
So right now I have hooked up like you have above and I am reading 24v on input pin on board. And the led does not flicker but as soon as I hook up the ground clamp it flickers same with float switch and breakaway switch. Which are on my inputs there on board.
I am not looking at buying another interface board or plasma. The plasma works fine with the proma so I will be doing away with the Mesa boards and thcad-05 and thcad-10 i am sure they work great when working but didn’t work out for me cause of my equipment. So if anybody is interested in a Mesa 7i96 and 2 thcad cards let me know I willing to ship wherever.
I have a Thermal Dynamics working with 2 x thcads and mesa hardware and its worked perfectly for me.
There has to be something you have missed somewhere.
