IMPORTANT: You need additional hardware from "Digi" (http://www.digi.com) for this App to work. The hardware must be capable of understanding the "Advanced Digi Discovery Protocol (ADDP)". Please refer to the user manual.
This App does most likely the same as the "Device Discovery Utility for Windows" that can be downloaded from Digi. But now you can have these features on your iPhone/iPod touch.
The App discovers all of your Digi devices connected to you network by sending a UDP/IP multicast datagram. After discovering you can edit the network settings of the device directly from your iPhone.
