OpenStage Application Server Support
For a server-based application, there are two possibilities to interact with an OpenStage phone:
The XML application platform allows for developing interactive applications using the graphical user interface of OpenStage 60/80 phones. When an application is running, the phone receives XML messages from the server via HTTP(S) and displays them to the user. The user, in turn, enters data and commands using the TouchGuide, the TouchSlider, and keypad keys. The phone sends the data to the server via HTTP(S).
The programmable keys (FPKs) of OpenStage 60/80/40/15 phones can be used to control any server or device that is accessible via HTTP(S). This is made possible by the 'Send URL' function. Moreover, with firmware version V2R2 onwards, the remote server has the possibility to provide feedback to the user by controlling the LED associated with the key. If desired, the status of the LED can also be changed in an unsolicited manner by sending a push request to the phone.
