How to update the Neuzeit Instruments Quasar

Download the firmware file (.ehex) from the Quasar section of the Neuzeit Instruments downloads page and install the Teensy Loader app (Mac, Windows or Linux). Turn off the rack but leave Quasar connected to the power bus, take it off the rails and plug a micro USB data cable into the Teensy board on the back of the module, then rest it back on the rails and turn the rack on. Drag the .ehex file onto Teensy Loader (or use Open HEX File) and enable Auto. Press the button on the Teensy board through the small hole on the back of Quasar with a toothpick or other non-conductive stick: Teensy Loader uploads the firmware in a few seconds. Turn the rack off, unplug the USB cable, mount Quasar again and power up; the loading screen shows the new firmware.
