# SIA DC-09 ARC Connection

Hi, and welcome to another evalink tutorial! 

In this tutorial, we will add and set up the SIA **DC-09 ARC Connection** Integration into your evalink talos account.

{% embed url="<https://youtu.be/CrvkZeLgMjQ>" %}

From your evalink talos dashboard, navigate to the menu `Company`, and click on the tab `Integrations`.

Search for **SIA** **DC-O9 ARC Connection**, and click on: `Add Integration`.

Now let’s configure the SIA DC-O9 ARC Connection integration.

First, click on:

`Add Connector`

Select a name, and choose a type: Trusted device, or Gateway.

{% hint style="info" %}
Trusted device is an experimental function which allows you to define a trusted device that acts as an alarm distributor. In most cases, you will select Gateway.
{% endhint %}

Next, select the 'Single or Dual Path polling configuration'. For this tutorial, we will select 'Custom Dual Path'.

Then enter the I.P. address, Port, transmission protocol, and polling interval for the Primary ATP Host, as well as, the I.P. address, Port, transmission protocol and polling interval for the Secondary ATP Host.

Configure the number of attempts to deliver an alarm before giving up, in the fields 'Attempts' and 'Attempts on D.U.H. response'.

To finish, click on the `Submit` button, twice.

Now, the next step is to enable and configure the **SIA** **DC-09 ARC Connection** on your site.

Navigate to the menu `Sites`, pick the site to configure, click on the tab `Integrations`, and then click on `DC09 Forwarding`.

Create a new forwarding by clicking on `Create DCO9 forwarding`.

Select the connector you have created and then enter the account number and shared key provided by the ARC.

Then, press `Submit`to finish the configuration.

Do you need to connect the SIA DC-09 ARC Connector onto more than one site?

Just go back to the menu `Sites` and repeat the process!

And...That’s it!

Now, each alarm received in your evalink talos account for this site will be forwarded to the desired ARC via the SIA DC-O9 protocol.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://sitasys-ag.gitbook.io/evalink-tutorials/dc09-arc-connection.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
