Check the values for resistors R1-R16.  If I remember correctly, D-Light changed those resistors to improve the board response with low current loads.  If your old board has the 180 ohm ones and the new board has 220 or 270 ohms, then that might be an issue.

Great right..   I now am noticing that one set of candy cane rows which has the exact same timing is reacting differently than the another. one board is a year newer. but the firmwares are at 1.17 on each board.   typically the slight diferrence would not be picked up but in this sequence I have them highlighting the double hi-hat. so it is pretty appearant. If someones willing to try the sequence for me or has expierenced this please shoot me a line.   Slink

I get that crap all the time. I have the roof lines and icicles split out to the closest controller to save wire and they are all the time doing different things. I have yet to figure out the cause. I plan to change out rs485 drivers all the way around to see if that helps. Carey
