Web Interface
You may use a standard web browser to access the ESP hub embedded web server. Any browser
that supports frames may be used, and the web interface is accessible from any system, regardless
of operating system type.
For information about when changes take effect, see When Changes Take Effect on page 12.
Accessing the Web Interface
The web interface may be accessed using any standard web browser with the IP address of the hub
as the URL. For example, if an ESP serial hub has an IP address of 192.168.0.5, entering the URL
http://192.168.0.5
will connect to the web interface.
The ESP-8 MI and ESP-16 MI serial hubs also support secure connections to the web interface. For
example, with an ESP-16 MI hub with an IP address of 192.168.0.5, entering
https://192.168.0.5
will initiate a secure connection. The browser will display the security certificate (self-signed) from
the ESP hub. Once the certificate is accepted, the web interface will open.
If the hub still has a default IP address (because it has not yet been configured or the hub has been
reinitialized), you may enter the URL
http://192.1.1.1 to access the hub (or https://192.1.1.1 for a
secure connection to an ESP-8 MI or ESP-16 MI hub).
NOTE: The predefined IP address (192.1.1.1) is fixed, and unexpected errors may occur if another device has
the same IP address or if there is more than one uninitialized ESP hub on the network. After the hub’s web
interface is accessed, you must configure an IP address before the hub becomes operational. After the IP
address is configured, the hub will no longer be accessible with the predefined IP address.
The ability to access the web interface is a configurable feature which is enabled by default; see
Configurable Features on page 29.
If you click the Documentation link in the Main Menu, you may then choose to download a copy of
this document (Installer/User Guide) or a sample configuration file.
Passwords
The web interface requires an administration password for access. When the ESP serial hub ships
(and after it is reinitialized), there is no configured password. When you access the hub, you are
prompted for a username and password. The username field is ignored. If a password has not yet
