My experience with the emulator is mixed. It's a great concept, but for the most part the drivers I need don't work. I have never seen a published list of emulator driver status, only indication on a driver-by-driver basis that one of them may not work. Some of the Modbus drivers work, though not all. I have had issues with some of the ones that do work too - serial framing issues that prevent the emulator from working but the actual G3 devices work perfectly fine. Beyond that, my expectation is that a given driver will NOT work in the emulator.
Now before I get bashed, my experience is with the drivers I need which certainly is not near all the ones listed. So it may be that every other driver works, and the small percentage I need don't. Could be. To know for sure, ask Redlion to publish a list. But I would prefer they focus on Crimson3 at this point, and come back to emulator drivers later!
