Sony UniLink protocol explained here, can someone?
Here's a link for the pinout and protocol for the Sony UniLink protocol. http://www.eriksen.no/unilink
This protocol controls CD-players in a Sony car stereo installation, as well as source selectors and DSP stuff. I don't think I'm up to it but if someone could build some interface to the pc, it would be fantastic. You could control your player with the head unit, which by the way would show you what is playing, and for what time. The possibilities are quite large but the interface to the UniLink bus seems quite complex. I guess you would need a microcontroller interface between the bus and the pc, if not more. But maybe the microcontroller can be ripped off the AUX-unit from Sony (XA107, don't own that one)? If someone has any idea's about this please let me know in reply's. I myself own a Sony head unit and a 10cd changer, so I'm willing to test some things out. This could be real nice if it works out!
I know this came up before, but not with this background info before http://www.mp3car.com/ubb/smile.gif
