So funktioniert das SONY S-LINK/CTRL-A(II) Protokoll |
How SONY's S-LINK/CTRL-A(II) protocol works |
|
| Dies ist eine kurze Beschreibung des Protokolls basierend auf BigDave's
und William Hollingworth's Ausführungen.
S-LINK oder CTRL-A(II) ist ein zweiadriges bidirektionales Bussystem vorwiegend im
Hifi-Bereich, an das viele Geräte gleichzeitig angeschlossen sein können. Vielen Dank an Jesper Nygaard in Kopenhagen (Dänemark) für seine Verstärker-, Tuner- und Surround Codes! |
This is a short description of the protocol based on BigDave's
and William Hollingworth's informations.
S-LINK or CTRL-A(II) is a two-wire bidirectional bus system mostly used in audio
equipment, where many devices can be connected together. Many thanks to Jesper Nygaard, Copenhagen (Denmark) for his great help finding amplifier, tuner and surround codes! |

| S-LINK (CTRL-A) protocol |
 |
Send a command to the device (I used here my MD recorder), it will
send back a reply message. Example: "get device name" you send: B0 6A you receive: B8 6A 4D 44 53 2D 4A 45 36 34 30 20 20 20 20 00 00 00 00 The device replies with its prefix, repeats the command and tells you "MDS-JE640". Great and easy bus system, eh? But you have to check for collissions! |
