The Link Isolator Kit provides upgraded protection against the electrical disturbances caused by ground offsets or static charges by placing an optical connection between the WeatherLink® data logger (WeatherLink) and your
computer. Since electrical disturbances cannot travel across the optical connection, the Link Isolator Kit will help prevent lockups of the weather station console and possible damage to the console, WeatherLink, and PC. The use of the
Link Isolator Kit is highly recommended when the weather station console and
the computer are not grounded or are connected to two different grounds.
