Check: During installation
-----------------------------------


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


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

    4. start UHDAS, try again

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
