I'd | also be remiss if I didn't mention the Slink-e [3], a commercial | product that seemed to be very capable (unfortunately it is now | discontinued). | | In fact, these protocols are (I believe) more capable than a | regular "Remote" socket since they allow bi-directional | communication, meaning you can both send commands to the | equipment and request data from them. But it's been a while since | I've looked at them in detail. | | Also, I recall being confused by the several (seemingly | incompatible) systems offered by Sony: S-Link, Control-A1 and | Control-A1 II. | | [1] http://www.brian-patti.com/s-link/ | | [2] https://github.com/Ircama/Sony_SLink | | [3] http://www.nirvis.com/slink-e.htm | tyingq wrote: | An 1/8 inch mono jack for remote control is somewhat common, but | there's no broadly accepted standards for the protocol.
