Yes it can. You just need to select the Shell (Empty) Preset for the PEMF coil, load the frequency program that you wish to drive it with, and then save it the generator for stand alone use.
The trick is to ensure you bind at least one frequency to the shell preset before you save it off to the generator, otherwise it won't have anything to run.
One you find and start it on the GX, ensure you enable looping, otherwise it will run only once (which may be for only 3 minutes) and then will stop.
