Sony KDX8500 Series Control Spec

Summary

Sony BRAVIA Professional Displays (KDX8500 series). Simple IP Control (SSIP) over TCP. Fixed 24-byte ASCII messages. Listens TCP 20060. Covers power, volume, mute, input select, picture mute, scene select, IR remote emulation, plus power/input/volume/mute push events.

Transport

protocols:
  - tcp
addressing:
  port: 20060
  # UNRESOLVED: host/discovery mechanism not in source (monitor located on LAN)
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable   # inferred from setPowerStatus examples
  - queryable   # inferred from get* enquiry examples
  - levelable   # inferred from setAudioVolume example
  - routable    # inferred from setInput examples

Actions

# Message format: 24 bytes fixed.
#   Bytes 0-1:  header "*S" (0x2A 0x53)
#   Byte  2:    message type - C=Control, E=Enquiry, A=Answer, N=Notify
#   Bytes 3-6:  FourCC command (4 ASCII chars)
#   Bytes 7-22: 16-char parameter (zero-padded decimal, or '#' pad for no-param)
#   Byte  23:   footer LF (0x0A)
# All command strings below exclude trailing LF (0x0A). Append LF when transmitting.
# Param padding rules: '#' = no-param placeholder; '0' = decimal zero-pad.

Macros

# UNRESOLVED: no multi-step sequences described in source.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no safety warnings, interlock procedures, or
# power-on sequencing requirements. Monitor setup steps (enable Remote Device
# Control, enable Simple IP Control) are configuration, not safety interlocks.

Notes

• Protocol name: SSIP (Simple IP Control). Sony BRAVIA Professional Displays proprietary.
• All messages exactly 24 bytes including trailing LF (0x0A). Implementations must append LF.
• Parameter padding: '#' = placeholder for no-param control/enquiry messages; '0' = decimal zero-pad for numeric values.
• Answer success = 16 '0' chars; Answer error = 16 'F' chars; "Not Found" / "Not available" = 16 'N' chars.
• Required monitor setup: [Settings] → [Network & Internet] → [Remote device settings] → [Control remotely] ON; then [Settings] → [Network & Internet] → [Home network] → [IP control] → [Simple IP control] ON.
• EU RED-DA models: 3 specification tiers; settings and available commands differ. Details not in this source.
• Scene name strings are case-sensitive; right-pad with '#'.
• firePictureMuteChange Notify semantics are inverted relative to other PMUT messages (0=mute on, 1=mute off) per source rows 201-202.
