I have just now had time to build my Ether Dongles (actually I built them when I first got them but have not had time to try and set them up. Everything seems fine. The green LED is on. I have an ethernet connection (port light is on). I am using LSP 2.0 to test. Thanks to Mickpat I think that I have LSP set up correctly. When I use LSPs hardware test utility, I can see commands going thru the port into the Ether Dongle (port light flashes). The hub and smart string hardware work fine. I was using the USB Dongle flashed with the Pixelnet firmware and everything worked fine. Everything seems to be working, but I have no light control at all. I have followed Mickpat's instructions on setting up LSP and as I say it seems to be working because the port light blinks when I send a command from the software. FYI, I used the EtherDongle2.hex to flash the chip, not the EtherDongle_DMX.hex. Could that be the problem? Any ideas?
