Welcome to the Sony S-Link Resource Center! This is a page devoted to understanding the Sony S-Link
protocol. Here you'll find links with information on S-Link, and a bulletin board where you can talk
with other S-Link adventurers.
S-Link is a protocol used by Sony A/V components to talk to each other. It encompasses Control-S,
an overall control protocol based on IR codes, Control-A1, a bidirectional protocol used to get CD information
from CD players, and Control-L, a time protocol used by high-end video components. Since most of the new
Sony components have an S-Link connector, and since Sony sells a box (CAV-1 or CAV-2) which allows a computer to
talk S-Link, it should be possible to build intelligent A/V systems based on S-Link. I have heard
of several people trying to do this; unfortunately, I know of few successes, in part because it seems
S-Link is poorly documented and understood.
Please note that this page is not provided or endorsed by Sony. Sony has chosen to provide very little
support for S-Link users or developers. An official site devoted to S-Link/VisionTouch developers was
closed in April, 1997; since then, Sony has limited support to those enrolled in its professional
developer program (which costs $5000 plus royalties).
- Sony's S-Link
Page A good overview of S-Link and its potential applications. No technical data, though. (Added 11/29/97 02:26)
- Sony's VisionTouch Page VisionTouch uses S-Link to control Sony components. Here you'll find info on the VisionTouch hardware and software that Sony sells, and the now-defunct Sony VisionTouch bulletin boards. (Added 11/29/97 02:28)
Coleman's Control-S Specification Mostly hardware-oriented info, to
enable you to interface to Control-S without a CAV-1 unit. There are some control codes here, but since the document was made in 1990, it's unlikely this is anywhere near a complete set. (Added 11/29/97 09:44)
- Dan Zenchelsky's VisionTouch Primer An excellent introduction to programming the CAV units. Includes a good introduction to the S-Link protocol. (Added 11/29/97 10:22)

- TitleTrack JukeBox Macintosh jukebox program that uses the slink-e hardware (http://www.nirvis.com) to control Sony changers. Great product. Nice GUI, plus supports AppleScript. (Added 8/01/99 18:43)
- Serial Interface to Sony DDD This documents how you can control a Sony DSS receiver via its serial port. It appears you can do more via the serial port than you can via IR or s-link. (Added 8/10/99 16:01)
