259 Light Limit With 4-String Differential Receiver Board?
« on: November 05, 2016, 02:20:17 PM »
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?

When you place the F16V2 into 32 string mode the max on any port is 340 pixels. Not sure why you can only get 259.

Ahhh, thanks David for pointing out my mistake.  When I changed the F16V2-R configuration to main board only or 16 string mode, 600 nodes are lit as expected.   I'm relieved it was something simple.

Hey there guys. Have a buddy who has a new falcon with differentials and receivers. He didn't realize he would be cut down to 340 pixels per port when going into 32 string mode. Can he run the differential in 16 string mode and get 680 on each output.

If not it's time to cut pixels!

He can run one receiver from F16V2 directly in 16 port mode.
