# Omniscan + NMEA Heading/Position

1. Add your Omiscan to the devices list:

{% hint style="info" %}
As a reminder, if the Omniscan is on your network, you can use the "Detect Devices" button to autopopulate the fields. 
{% endhint %}

2. After saving, add the NMEA source as a Generic GPS Device:

{% hint style="info" %}
You can also connect to NMEA sources via UDP with IP address and port
{% endhint %}

3. Add a new session with both devices:

Here's where you should be at:

With the Omniscan and gps powered and connectable, you should be able to connect to this session in discovery and use the Omniscan with heading and position.
