The shiny new replacement is a Davis Vantage Vue.
The data is transmitted from the outside ISS (Integrated Sensor Suite) to the consul indoors in a totally wireless system which is very robust.

The consul is now connected via USB to my iMac which pumps it out to my site on Weather Underground INOTTING18 - http://tinyurl.com/3ab5rkv.
