You'll want to write a RFQ (request for quote) to see how much it will cost for the new system.
If AMX is like the typical company there is no documentation for the users or programmers outside the company to write a new app.
If it wasn't clear what that meant, I'll state it plainly. You will not find a programmer to change the app. You will be replacing the system.
My company has 3 AMX NXT-CA7 touch panels and NI-2100 controllers to go with them in our conference rooms. We are tired of dealing with AMX's stringent rules and controls. What would be a good, independent programmer friendly, alternative that we could use to design, program, and install our own equivalent system? All functions are listed in this picture. Thanks in advance.
