# Commissioning the Pixy 2

{% hint style="info" %}
Further information of the Pixy 2 can be found [here](https://docs.pixycam.com/wiki/doku.php?id=wiki:v2:start).

The Pixy 2 can be commissioned and parameterized by the **PixyMon** software. A quick manual can be found [here](https://docs.pixycam.com/wiki/doku.php?id=wiki:v2:pixy_regular_quick_start). 
{% endhint %}

Within the PixyMon Software the Pixy 2 parameter for line tracking can be optimized. Following pictures show the nearly optimal settings for line tracking on the NXPCup track.
