We will be offering a training class at CEDIA on Saturday, September 25 at 4:00. At this class we will go into detailed examples of how to use the RS232 matrix to support popular requests like turning on/off TV's and controlling the volume on the AVR in a zone. This will include direct RS232 control examples, and RS232>IR examples. We also plan to make the RS232 over IP Software Developers Kit available to interested programmers at that time. In a nutshell, you can have as many RS232 controllers as you want simutaneously talking to any port on the Automation Matrix, independent of the HDMI over IP A/V Matrix.
Please send me a PM or an email if you want to guarantee a reserved spot in the class.
