1. Locate the power adapter jack on the end of the Envoy case. It’s next to the
data logger output cable.
2. Insert the power adapter plug into the power jack.
Optional: Connecting a Cabled Envoy to the Integrated Sen-
sor Suite (ISS)
Refer to the figure shown above “Connecting AC Power”.
1. Insert the modular plug into the ISS jack on the Envoy case.
Note: You won’t be able to test the connection between the Envoy and the ISS until you
have finished installing the WeatherLink software.
Optional: Adding an External Temperature Probe
(Wireless Envoy Only)
Your wireless Weather Envoy has a built-in temperature-humidity sensor as
well as the barometer. The temperature and humidity are reported as “Inside
Temperature” and “Inside Humidity.”
In some instances, such as when your Envoy is mounted outside in a shelter,
the temperature inside the shelter is of little interest. You may replace the
built-in temperature-humidity sensor with an external temperature probe, with
a 25’ (7.6 m) cable, which can be used to measure the temperature of air,
water, or soil. The External Temperature Probe with RJ connector comes in
