Show Pro Software uses a secure wireless network to connect to iPads. No Internet connection required.
At the moment we do not recommend 2 Show Pro licenses on the same network. This can cause connectivity problems.
Also, please note that there are built-in back-up systems in place for peace of mind. Not only can you print a show flow from the master computer and from each iPad (coming soon), you can also save the show flow as a .sho file locally or to DropBox and the iPads cache the latest show flow after each cue change or edit pushed by the master.
