When the yellow led is on and you see the USBasp in the System Profiler, you can upload the new firmware to the uDMX. Please contact me for instructions how to proceed.Īfter several tries nothing happens? Are your tweezers electrically conductive? -> don’t use plastic tweezers, this won’t work… Is there a hardware defect? Any loose wires? A bad solder joint? 4. If the yellow light goes on but the device enumerates as uBOOT, you’ve got a really old version of the uDMX with the first bootloader. Never mind if you accidentally touch the pin right next to it as well, but you should not short any other stuff on the board… I do it usually with a pair of metal tweezers, so I can keep the connection firmly with one hand while plugging in with the other. Whether you want to control a couple of traditional theatrical fixtures or a complex public installation featuring tens of thousands of LEDs, ENTTEC has a perfect software solution to fit your needs and budget. the yellow led should go on and the device should enumerate as USBasp (see above)Ĭonnect the following two points on the board: And this is where ENTTEC’s range of award-winning DMX lighting control software can make all the difference.plug in the uDMX (with pin D5 still tied to ground).short pin D5 (the leftmost pin on the bottom line of the Atmega8) to ground (the black wire of the USB cable).In that case, it might be possible to still force the uDMX into the bootloader: In some cases the firmware is broken beyond repair and the udmx doesn’t enumerate, so we cannot issue a software command to start the bootloader. The terminal should answer:–> Started bootloader on device “uDMX” (-5)Īnd if you refresh the System Profiler Window (Cmd-R) you should see the USBasp instead of the uDMX:
