3. User interface
3.1 Overview of user interface
DGA monitor runs a web server on its processing unit. The web server provides the user
interface of the DGA monitor. Access the user interface through Ethernet and a web browser;
no special software is needed.
Access rights are based on 2 fixed user accounts:
• Admin: full access for commissioning, configuration, and maintenance tasks. Requires
password to log in. Browser session expires after 3 hours of inactivity.
• User: limited access for viewing data and system settings. Cannot configure or control the
DGA monitor. Does not require a password. Browser session expires after one year of
inactivity.
The same Ethernet network that connects to the SCADA system is used to access the user
interface. Additionally, local access to the interface is provided by direct access to ETH1 port of
the processing unit.
3.1.1 Connecting to user interface
• Laptop computer with:
• RJ45 Ethernet connector
• Web browser (Google Chrome, Microsoft Edge, or Mozilla Firefox)
• Ethernet cable with RJ45 connectors for temporary use
• Administration password for this DGA Monitor
1. Connect your computer to the same network as the DGA monitor. If you are connecting
locally, connect the network cable between your computer and the port marked ETH1 on
the processing unit inside the DGA monitor.
2. Open a web browser, and enter the IP address of the DGA monitor in the address bar:
• If you connect locally through the ETH1 port, use the following IP address:
192.168.28.2
• If you connect through the network meant for SCADA integration, use the IP address
that has been assigned to the DGA monitor.
3. You will get a warning that your connection is not secure. This is expected and happens
when connecting with a new device. The user interface of the DGA monitor is secured
with a self-signed certificate by default. Continue despite the warning. HTTPS trac is
always encrypted even if the certificate is not trusted.
