# ROVL/Omnitrack

{% hint style="warning" %}
If using the ROVL over serial, please ensure serial devices are enabled in Session Configurations
{% endhint %}

{% hint style="info" %}
To run an ROVL with an external GPS, refer [here](/c/sonarview/session-configurations/rovl-+-nmea-gps.md). To output the deepside position as NMEA, refer [here](/c/sonarview/session-configurations/rovl-+-nmea-output.md)
{% endhint %}

Once your ROVL is connected to your computer, please use device discovery to connect to it (or a session containing the ROVL)\
\
After connecting to your ROVL, you should see something like this<br>

What you see above is the topside model on the default map tiles. Once a valid slant range is acquired (the topside can detect the trasmitter/transciever), the deepside model will show up as well.\
\
Once a position for the topside is acquired (either automatically via GPS or manually by providing coordinates), proper map tiles will be loaded in as long as you have internet or you have cached the tiles in that area.
