Create an EXIF Data String

As described in Menu → Data Input, SubC DVR+O / SCI provides the option of getting data from Rayfin Cameras and other applications or devices, such as those reporting environment sensor data: water temperature, depth, etc. and this data can be displayed on the video view as a Data Overlay and/or save to a specified file.

You can also create an Input data string that will automatically apply EXIF data to your images by combining multiple data sources into a single string.

For example, we can take the relevant information from the following sensors:
$GPGGA,202530.00,5109.0262,N,11401.8407,W,5,40,0.5,1097.36,M,-17.00,M,18,TSTR*61
$--DBT,3.3,f,1.0,M,0.5,F*hh
$--DBS,3.3,f,1.0,M,0.5,F*hh

And produce a data string in a format such as this:

$-EXIF,202530.00,5109.0262,N,11401.8407,W,1.0,1.0

Now the EXIF string is formatted correctly, and you can add this as a Data Input in DVR+O/ SCI

You can also confirm that the data is being received correctly by observing Menu → Stills Settings → Exif Data

You can also apply this Data as Overlays. See Menu → Overlays → Data
