To do this, you'd have to have a Wi-Fi wireless access point on the network which MAY raise security concerns. In any case, I've put web user interfaces on all the USL products I've worked on. On processors like the JSD-100 and JSD-60, you get fader control (up/down buttons), mute, and format select. You also get a bargraph display of the audio on all channels (and, if internal crossovers are in use, you see each band of each channel).
Though an HTML interface may not be as pretty as a custom application, it is pretty universal and will run on almost any device. But, it's not quite universal! I'm waiting for more browsers to implement the HTML5 range element to simplify definition of slider controls.

quote: Chris Slycord ... unless you jailbreak your phone, you won't be able to install the software you wrote (unless you pay the money to be an official, Apple-approved developer).
To elaborate: You can download the developer's kit for free if you have a compatible computer and operating system and you can use it to create apps for free. You can run these apps on the included iOS simulator for free. Then, you register with Apple ($99.00/yr. IIRC) which allows you to test your apps on real iOS devices. If you only want to write apps for yourself, you need not go any farther. If you want to distribute apps to other people you need to submit them to Apple. If approved, your apps will be available on the App Store.
Bad thing: It costs $$ to do this. Good thing: If the App Store sells your app for money, you get 70% of the proceeds.
If you can write an app for the iPhone, get it approved and sell it for $5.00 a copy you will make your money back with 29 sales. Everything over that will be profit.
I assume that the process is similar for Android and other mobile platforms.
I have been thinking about writing apps for iOS and I have been brainstorming for ideas on apps to write. I actually have been thinking of doing just this, writing an app to control a Dolby processor. Problem is, I need to know the commands to send to the device. Haven't had much time to really dig for that information.
Can anybody point me to where to look for the info?
I might get motivated to make an app or something else for the booth.
Do you think there would be enough people who would want such an app that I could make my money back? I wouldn't be in profit mode just yet. Only to earn enough to cover expenses.

My CP-650 manual has command strings described in appendix E.1. It only describes these as being for RS232, but they MIGHT be the same as those used over TCP. The CP-750 manual describes the TCP commands to control it. Similarly, the USL JSD-80, JSD-60, and JSD-100 manuals describe the TCP commands to control them. Writing a separate application to control every possible device in a theater gets cumbersome. That, again, is why I like web interfaces. No application needed! But since not everyone agrees with me, there is a need to somehow generate the specific TCP commands for each piece of equipment. The USL RTM acts as an interface between the wired control network and a browser on a Wi-Fi device. It handles all these conversions (and is a pain to keep updated - I have minimal involvement in that product but work on most of the other USL products).
So, if you want to do it as a pure application without an interface, it'd be interesting to include a device library in the application that you could keep adding to and updating. Lots of work, though!
Good luck!
