4.2 Configuration
4.2.1 Connecting to Configuration Tool
The WattStation Pedestal contains a configuration tool which can be used to establish owner
preferences and to setup the communication parameters for the customer’s network. The initial
connection to the Configuration Tool must be made via the Integrated Ethernet Communications port
(see Section 3.2.1). Subsequent connections to the tool can be made over WiFi after the wireless
network settings have been made to connect to the appropriate network.
The default IP address for the WattStation’s Ethernet communications port depends on whether or
not the cellular option is present. For the purposes of customer convenience, the WattStation is
shipped from the factory with default network setting of “DHCP enabled”. This means that the
WattStation will try to obtain an IP address from a DCHP server if one is available.
