Universal Input not updating rain

I am setting up a universal input station. Everything appears to be working except the rain. I saw a topic from 2006 that had this same problem but was not resolved. Is there a trick to get the rain totals in? Also what unit is used for the rain (mm or in)?

Is anyone using the universal input successfully? Are there alternatives to get data into weather-display from a custom application?

Hi
been away on school camp…
email me the file used and your settings file, wdisplay.ini
and I will test/check from here
