FYI,
The Conductor allowed standalone operation of the Etherdongle to output 16,384 channels of pixelnet (4 pixlenet universes).
The Conductor had the ability to send a sync packet to a Slave so that you could have another 4 universes of pixelnet 16,385 - 32,768
I don't believe the Slave will work without a Conductor as a standalone player.
If you are looking for a standalone player for the Etherdongle, I would look into the Falcon Player (FPP).
This can also have slave units.
