Web Interface
You may use a standard web browser to access the ESP-4 MI 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.
Using the web interface, you may:
•
Set and change your password
•
Display or change network configuration values
•
Display or change port interface, attributes and connection methods
•
Send a line break to a serial port
•
Display hardware information
•
Display or update Flash memory
•
Display or change configurable features
•
Download a configuration file
•
Launch the ESP-View diagnostic utility
•
Display general or port statistics
•
Display connection status
•
Reboot or reinitialize the hub
For information about when changes take effect, see
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-4 MI 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.
If the hub does not have a nondefault 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.
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 serial 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.
