You need Updaterator.
It's supposed to work with a Net3 Gateway, at least according to the release notes.
Hi Ueli
That is correct, you can use Updaterator with a Net 3 2 port gateway.
Connect to the internet once you have Updaterator installed and tell it to download the latest code.
The most recent version of Desire/S4 LED code is 1.6. Bear in mind that output is increased slightly in Lustr+ units with this version, so be careful if you have a show programmed already.
