3.6.8. Check: During installation

3.6.8.1. DAS does not start at all:

  • are there warnings or errors? Check /home/adcp/log for *.err and *.warn files

  • any mesage in *.warn or *.err will have more information in the matching *.log file

3.6.8.2. DAS does not start logging:

  • are the serial ports and baud rates all correct? Check

    • /home/adcp/config/sensor_cfg.py

  • Check your serial messages: they should all have checksums, they should be coming in at about 1Hz. If it is more frequent than that you can subsample the input; BEWARE: Only subsample if data are more frequent than 1Hz.

  • paths and permissions:

    • do the appropriate serial ports exist?

    • do the relevant serial ports all have a+rw permission?

    • does user adcp have +rw permission in /var/lock?

    • is there a directory /home/data that user adcp can write to?

  • are there extra files in /home/adcp/flags??

    1. stop logging, end cruise, kill UHDAS GUI

    2. remove all files from /home/adcp/flags

    3. kill all processes with “DAS”, or “ser_” in them

    4. reboot

    1. start UHDAS, try again

3.6.8.3. Logging starts but there are no plots:

  • are there warnings or errors? Check /home/adcp/log for *.warn files. These include:

    DAS_while_logging.warn, DAS_while_logging.log
