How to update the QX-hawk firmware when the unit does not respond to the normal auto connect. 1. Start the QX-Hawk in Safe mode. To do this , power the unit while keeping the Default pin (3) connected to the ground pin (7). In the standard QX cables, these are the green and blue wires. Keep the connection until the red cross comes on or for about 15 seconds. 2. Start ESP and force connect with communication settings 115,N,8,1. 3. Go to the ESP terminal. 4. Type and see if there is an answer. The unit should respond with the firmware versions and the text SAFE MODE. 5. Try to update the APP code which has been working before. The update can take more than 10 minutes. After the update, re-power the QX-Hawk. * If the update has succeeded, try to connect via Ethernet and update to the new Kernel, App code and the DSP code. In this order. * If the update has not succeeded, Force connect via RS-232 and update to the new Kernel, App code and the DSP code.
