Dynamic Host Configuration
Protocol (
DHCP) is disabled. These settings can be adjusted through SSi’s
nLocateIP
software
(see below), the web interface (
), or through the eFlo keypad.
If you already know the IP address of the web interface, skip to the Error! Reference source not
found.. The network configuration is described in this section.
The eFlo unit will use a default IP address of 192.168.1.200. If the unit is using the default IP
address, that IP address can be used to access the web interface (for more information on the
web interface, refer to the Error! Reference source not found. section.
The IP address of the unit can also be found by using SSi’s
nLocateIP
software. This method is
described in the following subsection.
