Messages can be imported and exported. It concerns only the messages of the first type, that is, data messages.

Export

To export messages from a unit, you should have the following access rights to it:

• Request reports and messages,
• Export messages.

To export messages to a file, request them and open the Export and import messages tab in the lower left section of the window. Select the destination format and click Export. Depending on your browser configuration settings, you will be offered to open or save the file. The file with exported messages can be compressed. For this, leave the checkbox Compress file marked.

The supported export formats are:

• OziExplorer track(.plt) — data format of the Ozi Explorer program that stores a track as 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 stored when exporting to this format.

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

Import

To import messages to a unit, you should have the following access rights to it:

• Request reports and messages,
• Import messages.

Saved files on the disk containing messages from the unit can be imported into the units you create. To import messages, select the Export and import messages tab in the left section of the window.

The supported import formats are:

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

Click on the empty field, specify the file to import the messages from, and click Upload.

To speed up and simplify the process, first compress the files with ZIP or GZIP utilities. When uploading is completed, the files will be unpacked and processed on the server. This process can be traced 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.

Consider the following 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.
