Hi I have an Extron Matrix Swticher. Extron was kind enough to tell me that it was an early model that they shipped with NO CONTROL SOFTWARE DEVELOPED!! They were also kind enough to tell me that they could fix me right up with only $350 US in charges. WOW ! I thought, what a great deal! ONLY around $700. CAn when all the exchange and shipping was sorted out, just to get this working the way it was supposed to out of the box! Needless to say, I was not amused by the joke that is Extron support. I guess if you're a multibillion dollar corporation, this is great support. If you're an individual end user, this is just a HUGE RIP OFF!! If anyone has a program that will allow me to control this switcher, I'd really appreciate it, thanks in advance, and beware of good deals on Extron stuff, they will take every chance to charge you and discourage use of anything but current products.
