# Connecting the GCS to the DeltaQuad Evo

Before connecting the GCS to your UAV, the Silvus StreamCaster must be connected to the Toughbook,  and both items must be switched on.

1. Follow the instructions in the chapter [**Silvus StreamCaster 4240-EP**](https://docs.deltaquad.com/tac/setup/ground-control-station-gcs/silvus-streamcaster-4240-ep) on properly setting up the radio module.
2. Connect the Ethernet plug from the Silvus breakout cable to the Ethernet port on the Toughbook.

4. Start the application **Auterion Mission Control (AMC**).

{% hint style="info" %}
Before launching AMC, connecting the Toughbook to a mobile hotspot or Wi-Fi network is recommended. The Toughbook uses internet connectivity to load satellite maps and for LTE communication with the UAV.
{% endhint %}

5. Pull out the rotary knob on top of the Silvus radio modem and set it to **1**.

{% hint style="danger" %}
Do **NOT** set the dial of the rotary knob to <mark style="color:red;">Z,</mark> as this is resetting the radio to its default settings. This makes the radio unusable.
{% endhint %}

{% hint style="success" %}
The Silvus StreamCaster 4240-EP is configured and set up properly in our factory. There is no need for further configuration. The system is plug-and-play ready.
{% endhint %}

6. Switch on the DeltaQuad Evo. Follow the steps described in the chapter [**Powering the Vehicle**](https://docs.deltaquad.com/tac/setup/powering-the-vehicle).
7. During initialization, the GCS and the DeltaQuad Evo automatically establish a connection. The bi-color Status LED on the Silvus radio modem should change from red to green.

The following list provides an overview of the possible LED color codes and their corresponding meanings.
{% endhint %}

<table data-header-hidden><thead><tr><th width="291"></th><th></th></tr></thead><tbody><tr><td><strong>Red</strong></td><td>The radio is in the process of booting up.</td></tr><tr><td><strong>Flashing Green</strong></td><td>The radio is fully booted but not wirelessly connected to the vehicle.</td></tr><tr><td><strong>Green</strong></td><td>Spectrum Scan is in Progress. Connection to the vehicle has been established.</td></tr><tr><td><strong>Flashing Red</strong></td><td>Radio has recovered from a bad state and has reverted to factory default settings.</td></tr><tr><td><strong>Rapid Flashing Red for 1 second</strong></td><td>The battery is less than or equal to 20%. LED will blink red rapidly for 1 second then go back to normal. This will repeat every 5 seconds.</td></tr><tr><td><strong>Rapid Flashing Green</strong></td><td>When the multi-position switch is rotated to a new position, the LED will rapidly flash green while the new settings are being applied. The LED will return to normal indication once the settings have been applied.</td></tr></tbody></table>

8. In the upper left corner of AMC, the vehicle status indicator will show the connection status to the DeltaQuad Evo. When the indicator is green (**Ready to Fly**), the vehicle is ready for takeoff.
