# Setting up the network connection

### Network Setup <a href="#toc112837532" id="toc112837532"></a>

All relevant components (robobrain®, Human Machine Interface (HMI), and robot) communicate via network (Local Area Network, LAN). The robobrain® is delivered with the IP address <mark style="color:blue;">**192.168.0.5**</mark> on <mark style="color:blue;">**p**</mark>*<mark style="color:blue;">**ort 1**</mark>* and <mark style="color:blue;">**DHCP**</mark> on <mark style="color:blue;">**p**</mark>*<mark style="color:blue;">**ort 2**</mark>* by default. This may have to be adapted to the network structure. The shared network allows the user to open the network-based HMI on a web-browser to monitor and parameterize the system. The figure shows the network structure and the logical connections between the individual devices.

{% hint style="info" %}
If you do not know which IP address was assigned by the DHCP server for the robobrain®, you can look it up on the system. In order to do this, you only need to connect a monitor to the graphic card. The IP information is then displayed on the monitor. To access the HMI, the displayed IP must be called up from any computer in the Internet browser.

<mark style="color:blue;">**Step 1:**</mark>**&#x20;Hardware connection of the components**

Connect the components according to the figure above. For example use the <mark style="color:blue;">**Ethernet port 1**</mark> from the robobrain®. Regarding the camera, it is important that the robobrain.eye is connected to an USB 3.0 port of the robobrain®.

{% hint style="info" %}
The components (robobrain®, HMI device, and robot) can either be integrated into an existing network or connected with a dedicated network (e.g., via a network switch). It is also possible to connect the robobrain® directly to the display device via an Ethernet cable. This setup allows the configuration of the robobrain® without adding the display device to the network with other devices like robots and grippers. To enable this connection it must be ensured that both, the robobrain® and the display device have different static IP addresses in the same address space. Consult your network administrator for the optimal solution for your network infrastructure.
{% endhint %}

<mark style="color:blue;">**Step 2:**</mark> **Setting up the network configuration of the respective devices**

To change the network configuration of a robobrain® its HMI is used. Therefore, a display device with a web browser (e.g., laptop, tablet) must be connected to the robobrain® via network. Then it is possible to access the HMI by entering the robobrain®’s IP address into the browser of the display device.

{% hint style="info" %}
The IP address of the device, with which you want to open the user interface or HMI must be in the same IP address range as the robobrain® system.
{% endhint %}

If the robobrain® is still in its factory state the IP address is <mark style="color:blue;">**192.168.0.5**</mark> (Ethernet port 1). In order to access the HMI the display device must be able to reach this IP address. The full network configuration of Ethernet port 1 is:&#x20;

| <mark style="color:blue;">Standard IP:</mark> | 192 | 168 | 0   | 5 |
| --------------------------------------------- | --- | --- | --- | - |
| <mark style="color:blue;">Subnet Mask</mark>  | 255 | 255 | 255 | 0 |
| <mark style="color:blue;">Gateway</mark>      | 192 | 168 | 1   | 1 |
| <mark style="color:blue;">DNS 1</mark>        | 192 | 168 | 1   | 1 |
| <mark style="color:blue;">DNS 2</mark>        | 8   | 8   | 8   | 8 |

{% hint style="danger" %}
*If the robobrain® is integrated into an existing infrastructure, it must be ensured that the IP <mark style="color:blue;">**192.168.0.5**</mark> is not yet assigned. This may lead to conflicts and may cause the robobrain® to not be reachable anymore.* Consult your network administrator for guidance.
{% endhint %}

<mark style="color:blue;">**Step 3:**</mark> **Change network configuration of robobrain®**&#x20;

After connecting a display device to the robobrain® and accessing the HMI it is possible to change the network configuration under <mark style="color:blue;">**Options->System->Network Connection**</mark>:

<figure><img src="https://660378187-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FbfPmWtourffXBtJHjy1q%2Fuploads%2FurOQthhToQ4J4yQ0Sx7q%2Fnetwork_connection.png?alt=media&#x26;token=58dd8ba6-d48a-4013-83b8-750b00d4bd65" alt=""><figcaption><p> Accessing the network connection from the starting page</p></figcaption></figure>

You have the option to enter the IP address manually or use DHCP.

{% hint style="danger" %}
*Before applying any changes to the network configuration, ensure that the new configuration is correct. It is also a good practice to write down the new network configuration or take a screenshot before applying the changes. **After applying the changes to the network configuration, the robobrain® can only be reached through this configuration.** Any error in the configuration might result in the robobrain® not being reachable anymore. At the moment there is no way to reset a robobrain®’s network configuration without its HMI.*
{% endhint %}

A convenient option for the network configuration is to keep the setup for Ethernet <mark style="color:blue;">**port 1**</mark> at its factory state. This port can now be used for maintenance by directly connecting a display device. Ethernet <mark style="color:blue;">**port 2**</mark> is then used to connect the robobrain® to the network containing the other relevant devices and change the configuration of <mark style="color:blue;">**port 2**</mark> accordingly. Adding a display device to this network is optional since port 1 can be connected to a display device for configuration and maintenance.
