If the user attempts to place two devices of the same type in a World with the same Device ID, a Duplicate Devices conflict will occur. The Vocia system relies on each Device having its own ID number to identify it amongst other devices of the same Type.
This window can be accessed by clicking on the Duplicate Devices tab (shown below) in the bottom right hand corner of the Vocia software or via the Network Menu. The software will use the MAC address in each device to identify them.
One of the devices must have its power removed and then it's ID changed. Once this is done then the device can be plugged back into the system, discovered by the software and programmed.
