Same way here, the 2010 display was maxed out using the LOR mini director in my display.
176 DMX channels and 600 channels of CCR using LOR did it in.
If we cannot get more speed out of the communications and have all pieces with the same ability to handle the same speed we will have problems. Had too increase the port speed from 57.6K to 115.2K to get some of the events to work, but also had misfires on the DMX and LOR sides.
What I found out is LOR mini director cannot handle 20ms events reliably, Lynx wireless speed is slightly slow.
If your minimum events are 50ms you would not see any but DMX can handle 25ms events.
Now what about Pixelnet? what is the maximum event speed?
