JMRI software

There is a freeware software package called JMRI that is quite a boon to DCC users.

(Java Model Railroad Interface - Java is a programming language)

The main program runs on Windows, Linux, or Mac (which is Unix).

It has a lot of functions, and can perform as a database for your cars and locos and will program DCC CV's and also has "servers" that allow wireless control.

The wireless control consists servers that support a "web" interface that can be used from most computers with an Internet browser (but not really good on phones), and a server that supports apps on a smartphone, specifically Android and iPhone.

These apps are available separately, the Android one is free, the iPhone one has a free limited one, and a $$ one with more features. (go android).
