Keitha has is correct. The EDT just sends out 4096 channel universes. It is the Active hub that can convert a 512 chunk of channels to DMX. However, just because a 512 chunk is getting sent out as a DMX signal, does not stop the full 4096 channels from being sent to all pixelnet devices on that active hub. You can set up a 16 channel LE starting at channel 1 and setup 16 channels of RGB starting at channel 1. If you turn channel 1 on, both the DMX chan 1 and the pixelnet chan 1 will turn on. Hope that is clear. The key is that when you are doing your programming and when you are doing your hardware configurations you must be aware of your channel numbering so that you are not sending commands to the wrong set of lights.
