I am hooked up to my pixelnet dongle, connected to my smart string active hub. Powered up my 750w Thermaltake single rail ps. One of the 16 smart string outputs is connected to a SSC that was successfully programmed with my picket2. Jumper is in program mode on SSC. Pixelnet universe 1, dmx 1 jumpers are in place on Smart string hub. SS utility opened, start channel selected, string length selected, etc. Transmit....NOTHING!!! Checked known working lights, nothing. Checked known working cat5 cable, smart string hub output, nothing nothing nothing...I programmed 10 SSC v4 successfully now nothing. I have repeated this 6 times on 6 more SSCv4 now without any response. I have gone back and re flashed. erasing memory has led to this message "program memory is not blank starting at address 0x000000." Now not allowing me to program. any ideas??? <fp.
