5.11.3 HTTPS
The requirement for using HTTPS for secure communication via the Internet and mobile
wireless network with the CMR is a SIM card for the CMR with a publically accessible IP
address.
For information on the functions and requirements, refer to the following sections:
Further functions (Page 15)
Requirements for use (Page 18)
HTTPS
● Enable HTTPS on the mobile wireless interface
Select the option to enable secure communication with the CMR via the internet and the
mobile wireless network using HTTPS. To achieve this port 443 on the WAN interface is
opened.
Note:
HTTPS is always enabled on the LAN interface.
Note
Connections with HTTPS access via the mobile wireless interface
The CMR makes precisely one connection available on the mobile wireless interface. You
should therefore use browsers that also only operate with one connection (FireFox). With
browsers that require at least two connections (e.g. Internet Explorer 11, Edge, Chrome) no
functioning connection will be established or the Web pages will not be displayed correctly.
Note
Updating pages with HTTPS access
Use the following options to update and reload a Web page:
• The WBM button "Update"
•
Click on the link of the required page in the navigation on the left in the browser window
•
Repeat the entry in the address line
Avoid updating pages using the standard browser mechanisms ("Reload page" or F5).
Depending on the device and the mobile wireless network, the setup of the pages can take
several seconds and with a bad connection or cell change be interrupted.
Own certificate
In the factory settings the CMR uses a self-issued server certificate for authentication with
the communications partner (client). In the browser of the PC from which you want to
connect with the CMR, in this case a message is displayed when establishing the
connection.
