HPC LS3040 setup HELP, I cant find my machine

I have recently bought a HPC LS3040. I believe its a few years old. I don’t think it’s on the Ruida controllers, I think its the older one. I’m struggling to ‘find’ my machine (is this done with the printer cable on the side?) . So I was going to add manually however not sure what to set up as. Can anybody help with this? Much appreciated.

If it uses a Leetro controller, you’re out of luck, as those are not supported by LightBurn.

This is a Leetro:
