Check the software or license documentation to confirm that it supports the existing control processor family, since some licenses work only with a specific processor type. Then verify that the mobile device runs a supported operating system, such as iOS, before installing the app and activating the license.

For local control, plan for a Wi-Fi network that connects the mobile device to the compatible control processor. Off-site access can use Wi-Fi or 3G or 4G connectivity, with automatic switching between available connection types.

Mobile device control software can support two-way feedback, including cover art, text, dynamic scrolling lists, and other system status updates. It can also store control programming on the mobile device and update it when system changes are made.

Plan the license around the number of Apple mobile devices that need access to the same control system, with one-user and five-user options available for different project sizes. Activate the license in the control system’s programming file and confirm that it matches the processor platform, since licenses are platform-specific.
