The MK2 and the older Pro have different initialization strings, since the MK2 can be set to do multiple universes (for one thing). I do not have the M-PC software, but my guess would be that since the MK2 is not listed as a setup option, the M-PC software is not scanning for it specifically. Since you say other packages 'find' the MK2 (you can try mine as well), the conclusion would be that an update is needed for the M-PC package for the newer device. The Open device does not have an internal timer for
DMX and wants to communicate via a usb to serial communication internally. Even if you get it to work, controlling over 24 channels will be spotty. But, again, the init string is different and if the M-PC software is not sending it... You could check when you have your second
screen up, that in Device Manager under serial ports, you see an
Enttec device.

line - I would see if
Martin has an update for the MK2.
