If a console is updated to OS 2.0 from a very old software (e.g. Version 1.5 or lower) it potentially will not have received a new license string for the HASP dongle inside the Maxxyz.
The symptom will be that no show related DMX is sent from the console and the commandline indicates "OFFLINE" (similar to a demo Maxxyz PC version)
A properly working console will state "LIVE" on the command line.
The HASP dongle needs to receive the updated license string by downloading and installing a small tool:
Run this tool from a CD or USB device (front port) and reboot. The Maxxyz will now indicate LIVE in the beginning of the commandline and show related DMX data is sent.
