Retrieving Data from the Recorder
3.1
Communication Errors
1.
Timeout on command echo.
There is no response from recorder. The recorder is off-line. Please try to
connect again.
2.
Other communication errors while retrieving data.
The result of the retrieval can be viewed in the .MIT file. Usually, if the
communication is in order and all the data is retrieved correctly, SeaStar will
automaticlly convert the data from the decimal values (.DAD) to the unit values
(*.DAT). If this is not the case, then SeaStar may drop the conversion part and
it is up to the user to either retrieve the data again or manually re-convert the
data, depending on the status of the retrieval. If a communication error occurs
in the middle of data retrieval, the recorder goes off-line. The user must
connect to the recorder again and retrieve the data again.
3.
Communication errors while updating recorder status.
In the event that a communication error occurs while updating the status in the
recorder, i.e. after retriving the data, the CRC register in the recorder is
probably corrupt. Thus when connecting again to the recorder, a CRC error
will likely occur. In this case, the CRC check should be disabled, as described
under CRC error in chapter 1.3.
