4. Locate a free Ethernet port on your broadband or DSL router and connect
the cable to the port.
5. Reconnect the AC adapter.
Note: An Envoy using a WeatherLinkIP data logger requires use of the AC-power adapter.
Battery power can be used for short-term backup power in the event of a power outage,
but an Envoy with WeatherLinkIP should use the AC-power adapter as its main source of
power.
The Weather Envoy beeps two times, occurring within one second of each
other. On power-up, the IP data logger will negotiate its connection with
the router.
6. Write down the Device ID and Key located on the side of the
WeatherLinkIP data logger for further use.
The Device ID (DID) and Key uniquely identify your data logger on the
WeatherLink Network (www.weatherlink.com). They are both required to
create a login on WeatherLink.com and are used to connect the
WeatherLinkIP data logger to the software.
Note: Because WeatherLinkIP is continuously uploading current weather information to the
www.weatherlink.com, leave the WeatherLinkIP and Envoy connected to your router at all
times.
