Sony KDX8508 Series Control Spec

Summary

Sony Bravia professional display series supports Simple IP Control — a fixed 24-byte TCP protocol on TCP port 20060 for controlling power, audio, video input, picture mute, scene setting, and IR-equivalent remote commands over a local network. No authentication required. EU-area models ship with three RED-DA specification variants and differing command availability. Both wired and wireless LANs are supported.

Transport

protocols:
  - tcp
addressing:
  port: 20060  # stated: "control listening port is TCP 20060"
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable  # inferred from setPowerStatus / togglePowerStatus
  - queryable  # inferred from getPowerStatus / getAudioVolume / getAudioMute / getInput / getPictureMute / getSceneSetting / getBroadcastAddress / getMacAddress
  - levelable  # inferred from setAudioVolume / getAudioVolume
  - routable   # inferred from setInput / getInput
  - muteable   # inferred from setAudioMute / getAudioMute / setPictureMute / getPictureMute / togglePictureMute

Actions

# All commands are 24-byte fixed TCP messages on port 20060.
# Header = 0x2A 0x53 ('*S'), Message Type byte, 4-byte FourCC, 16-byte params, 0x0A footer.
# Control type = 0x43 ('C'), Enquiry = 0x45 ('E').

Notes

Protocol format: Fixed 24-byte TCP messages. Header *S (0x2A 0x53), Message Type byte (C/E/A/N), FourCC command (4 bytes), Parameters (16 bytes), Footer 0x0A (LF).

Example — Power OFF request: *SCPOWR0000000000000000 → *SAPOWR0000000000000000 *SNPOWR0000000000000000 (Accepts + current status Notify).

IR Commands (via setIrccCode): Full remote button code table documented — Display, Home, Options, Return, Up/Down/Left/Right, Confirm, Red/Green/Yellow/Blue, Num0-9, Volume Up/Down, Mute, Channel Up/Down, Subtitle, DOT, Picture Off, Wide, Jump, Sync Menu, Forward, Play, Rewind, Prev, Stop, Next, Pause, Flash Plus/Minus, TV Power, Audio, Input, Sleep, Sleep Timer, Video 2, Picture Mode, Demo Surround, HDMI 1-4, Action Menu, Help. Codes are zero-padded to 16 bytes in the parameter field.

EU RED-DA note: EU area models have 3 specification types with different command availability. Not all commands available on all EU variants.

Required monitor settings: Remote Device Control must be enabled at [Settings] → [Network & Internet] → [Remote device settings] → [Control remotely]. Simple IP Control must be enabled at [Settings] → [Network & Internet] → [Home network] → [IP control] → [Simple IP control].

Network: Both wired and wireless LANs are supported (stated in source).

Diff vs rev 2: Traits filled (was comments). Revision 2→3. Summary +1 sentence on wired/wireless LAN. Notes +1 line on network. 2 new UNRESOLVED markers (asterisk meaning). All action/event/feedback IDs + shapes untouched.
