I've run into an issue with my F16V2-R controller with a 4-string differential receiver board. I'm planning to use the differential receiver board for a megatree with 16 strings with 100 lights each. I've configured the F16V2-R serial outputs for strings 29 -32. I've also configured the F16V2-R string outputs 29 & 30 for 6 strings each and string 31 for the remaining 4. String 32 will be used for a megatree star topper with 90 lights. The issue I've run into is there seems to be a consistent limit of 259 nodes that light up from the differential receiver. I started with firmware 1.11 b002 and upgraded to 1.11 b003 and still have the issue. I've tested all my strings individually and they're all good. I also inject power at the end of each string, so power shouldn't be an issue either. I've successfully light 654 nodes from one F16V2-R port, but only 259 from the 4-string differential receiver. I was hoping to use the differential receiver board, but if I can't get it to work I'll have to run three relatively long lines from the F16V2-R. Any suggestions on what else to try?
