For upgraded protection against the electrical disturbances caused by ground offsets or static charges, install the Link Isolator Kit between the WeatherLink data logger and your computer. Uses optical coupling of signals to prevent lockups of the weather station console and possible damage to the console, data logger, and PC. Recommended when the console and the computer are not grounded or are connected to two different grounds. Includes 40 ft (12 m) cable and power adapter.
For use with the Perception, Weather Wizard III, and Weather Monitor II only.
