3. Once downloaded, you will need to save the data file in a directory with a unique file name - we recommend checking the box next to "Use Date String" to keep file names unique. Data from the receiver will be saved as a binary .BIN file which will need to be converted in the next steps.\

   1. With the Download Data dialog box still open, click button "View" button next to the save button
   2. OR: Click "CodeLog Records" from the main menu.\
      ![](/files/QkGZln9klC8JHE4frv7h)\
      Then click the "Load" button and select the BIN file you want to convert.\

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.motus.org/en/stations/downloading-data/lotek-srx.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
