The Conex WeatherJack is a small, battery operated weather instrument in the form of a module. It operates as an electronic barograph and thermograph and connects to the serial port of your PC via an RJ11 telephone type cable and RJ11 to serial (DB9) adapter (both provided). A small phone jack is also located on this end that allows you to connect the included external temperature sensor to the unit.

Once the WeatherJack software is installed on your PC (Windows 98 or XP) and the unit is connected, you can monitor both the barometric pressure and the outside temperature in the form of a temperature and pressure graph on your computer.

You can easily follow weather fronts as they pass over you area and monitor daily temperature fluctuations over a three day period. Options allow you to set the sampling frequency from 15 minutes to 1 hour. Special rate of change icons warn of fast changing pressure changes that generally indicate the approach of severe weather.

Other options allow you to set the pressure to either millibars or inHG and the temperature to either F or C.

Historical information is stored on your computer and can be recalled at any time.
