For KerberosSDR users, please update the EEPROM as described above first, then reboot. Once the web interface has loaded, expand the "Basic DAQ Settings" by clicking on the checkbox. Under "Preconfigured DAQ Files" select "kerberosSDR_default", and then click on "Reconfigure and Restart DAQ chain". This may take a minute or so, but after it's completed the software should connect and begin processing. If 'Reconfigure and Restart DAQ chain' does not fully restart the software after a few minutes, please perform a hard or soft reboot of the Pi4. +## KerberosSDR Reconfiguration (For GNU Radio) + +Please update the EEPROM as described above first, then reboot. + +SSH into your heimdall_daq server and edit the text file in `heimdall_daq_fw/tree/main/Firmware/daq_chain_config.ini`, changing these parameters to the following. + +``` +num_ch = 4 +en_bias_tee = 0,0,0,0 + +cal_track_mode = 0 + +iq_adjust_time_delay_ns = 0,0,0 +adpis_gains_init = 0,0,0,0 +``` + +Save, and restart heimdall. + ## KerberosSDR Retuning The KrakenSDR code is designed to autocalibrate phase on each retune. Unfortunately this feature is not available on the KerberosSDR due to the lack of a noise source switching circuit. So with the KerberosSDR every time you change the frequency or DAQ settings, you must make sure that you have the antennas disconnected. (NOTE: This is only a problem for the DoA software which requires sample and phase calibration. For PR only sample calibration is required, and hence retuning should be fine without needing to disconnect antennas.) -- cgit v1.2.3
