Approach 2:
If the WattStation does have the cellular router option, the cellular router does have an internal DHCP
server and will provide any DCHP clients connected to it IP addresses starting with 192.168.13.100.
This makes determining the IP address of the WattStation more complex, since multiple WattStations
may be connected in addition to the computing device you are using to browse into the configuration
tool. In this case, you should start by trying to log into the tool at 192.168.13.100 and increment the
last byte (i.e. 100 -> 101, 102, 103, etc.) of the IP address until all WattStation units are configured.
Note that your computer may be one of these addresses and unless you happen to be running an
HTTP or HTTPs server on it your browser should respond that it could not connect.
Type into URL window:
https://192.168.13.100
Your browser will likely respond with a screen questioning the security of the WattStation’s https
server. This is fine and to be expected (see section 4.2.1 – Accepting Connection to the Configuration
Tool).
Note that if multiple WattStations are sharing a cellular connection (see section 3.2.3), then it may not
be immediately obvious which WattStation is 192.168.13.100 vs. 192.168.13.101 and so forth. If all
WattStations are being configured the same way this shouldn’t make a difference. If on the other
hand the WattStations need to be configured differently from each other, then simply disconnect the
cellular router’s Cat5 cable (it will be the blue one connected to the Ethernet switch) and disconnect
any daisy-chain Cat5 connections between the individual WattStations’ Ethernet switches. Reboot
the system and configure each WattStation using Approach 1. After configuration is complete,
reconnect all the Cat5 cables back to the desired network configuration and reboot the system.
4.2.2 Accepting CCoonnnneeccttiioonn ttoo tthhee CCoonnffiigguurraattiioonn Tool
The WattStation configuration tool runs over a secure http server that uses a so-called self-signed
digital certificate that was created by GE Industrial Solutions specifically for the WattStation. Since
this certificate was not issued by a trusted SSL certificate provider (e.g. VeriSign or GoDaddy.com), the
browser will issue an alert or warning questioning the trustworthiness of the certificate before loading
the page.
