I recently acquired a prolight 1000 cnc mill. It didn't come with a controller box. I was planning on upgrading to g540 but I found a spectralight controller box for light machines/sherline cnc. The controller box looks almost exactly like the one that would have been used for prolight. The only difference is that some of the label names and plugs are slightly different. I believe its made by the same company. My question is, are these two compatible? Can I use this one for my prolight?

What the prolight controller would have looked like:
