Brian - Florida - USA Posted June 30, 2011 Report Share Posted June 30, 2011 Hi! I'm looking for a way to control a Sony AV Receiver using Control-A1 II. I found this site by searching for the Sony "PC interface kit" that is mentioned in my AVR's manual. I believe that this page contains the info for the interface kit. Where can I buy one of these (with the software)? I believe I can use it to send the Control-A1 signals to my AVR. Any help is much appreciated. Thanks, Brian Quote Link to comment Share on other sites More sharing options...
sfbp Posted June 30, 2011 Report Share Posted June 30, 2011 Sorry Brian but I suspect you are largely out of luck. The next generation (PCLK-MN10/20) are available on Ebay but the one you want is probably impossible to find. You might try on yahoo japan, if you can manage to navigate all that. But I had a quick peek and found nothing. Your AV receiver is so old it might be a smart idea to upgrade to something about 10 years younger. I'm not suggesting current by any means - more like something about 4-5 years old. The PCLK-MN10/20(A) series does essentially generate the right control signals but I think they are in a form that is mostly useless to you. There are folks here who understand the details of SIRCS and Ctrl-A1(/II) but the details were never really published properly by Sony. Consequently it never became any sort of standard.

Brian - Florida - USA Posted July 1, 2011 Author Report Share Posted July 1, 2011 Thanks for the reply, sfbp. I saw the MD10 and 20, and I like the fact that it has a USB interface, but it has a different Control-A1 connector than I need. Also, I figured that it would be easier to scan the serial interface to figure out the protocol between the PC and the adapter so I can write my own code. Do you think it might be possible to make an adapter to go from the DIN connector on the M10/20 to plug into my receiver? Do they just use the same 5-volt/0-volt pulses with a 600uS timing and a 2400uS start-of-message pulse? Oh, and as for getting a more current receiver, I'm happy with mine. I really don't think I need HD Audio and HDMI switching. I can do the HDMI switching with other means and I really don't think I'll be able to tell the difference between the older digital audio formats and the new ones... especially not in a movie. Plus, I really don't want to spend $1K or more on a new receiver. Quote Link to comment Share on other sites More sharing options...
sfbp Posted July 3, 2011 Report Share Posted July 3, 2011 I don't think the output is Control-A1. My 3 year old Onkyo (at the time i bought it) cost me $225 and works like a champ. Why fight the older version of everything? (I'm not suggesting you purchase anything NEW). Quote Link to comment Share on other sites More sharing options...
