Accessing the Configuration Utility
The configuration utility may be accessed three ways: with Telnet, by serial connection to port 1
when the ESP-4 MI serial hub has no configured IP address or by serial connection to the port(s)
that have the configuration utility connection method enabled.
Accessing with Telnet
You may initiate a Telnet session to the IP address of the ESP-4 MI serial hub and the standard
Telnet port 23. For example, if a hub has an IP address of 192.168.0.5, entering
telnet 192.168.0.5
23
will connect to the configuration utility.
If the ESP-4 MI serial hub does not have a nondefault IP address (because it has not yet been
configured or the hub has been reinitialized), you may use the predefined IP address of 192.1.1.1 to
access the hub.
