FAQ for eDMX2 PRO

Can I power the eDMX2 PRO from the USB power on an Airport Express

No, the USB port on the Apple Airport Express is designed for memory sticks, it does not provide enough power for anything else. If the eDMX will cycle on and off the network (basically reboot every few seconds) that is an indication that it doesn't have enough power (current) and is the symptom when powered by an Airport Express. Use a standard USB phone charger (0.5A) instead.
