Export

To export messages to the file, follow the steps below.

1. Open the Messages tab.
2. Select the unit in the drop-down list. 
3. Specify the request interval and select the type of messages.
4. Click Execute. You can request messages in other ways.
5. Go to the Export and import messages in the lower-left part of the window. 
6. Select the format of the resulting file.
7. Enable the Compress file option, if you want to create an archive with exported messages.
8. Click Export. 

Depending on your browser settings, the created file will be opened immediately or you can specify a path for saving the file.

The supported formats are as follows:

• OziExplorer track (.plt): data format of the Ozi Explorer programme, a list of coordinates of the track points.

• NMEA messages (.txt): a text file of the National Marine Electronics Association. This text protocol is used for marine navigation equipment.

  Parameters (sensors) are not saved when exporting to this format.

• Google Earth (.kml): an XML-based format used in the Google Earth programme to transmit three-dimensional geospatial data.
• Wialon messages (.wln): a format used with the Wialon software.
• Binary Wialon messages (.wlb): a binary format used with the Wialon software.

Import

The files saved on the disk which contain messages from the unit can be imported into the units you create.

The supported formats are as follows:

• Raw navigator logs in the GPRMC format defined by the NMEA 0183 specification: search in files with the .txt or .log extensions.
• Wialon messages: search in files with the .wln extension.
• Binary Wialon messages: search in files with the .wlb extension.

To import messages, follow the steps below:

1. To speed up and simplify the upload process, compress the message files using ZIP or GZIP utilities beforehand. You can skip this step.
2. Go to the Export and import messages in the lower-left part of the window. 
3. Click on the empty field and select the file from which you want to import messages.
4. Click Upload.

Once the upload is complete, the files will be unpacked and processed on the server. You can track this process in the log.

Afterwards, you can request the imported messages and view them in the table. If the messages have been imported by mistake, you can delete them in the table individually or in bulk. You cannot select more than 1000 messages to delete at a time.

Import particularities

• If the parameter name contains more than 40 characters, then the message is imported without this parameter.
• If messages with parameters of digital inputs and outputs are imported in the wln format, then the parameters inN and outN are replaced by avl_input and avl_output, respectively.
