JBL SDR-35 RS-232 / IP control commands

Summary

JBL Synthesis SDR-35/SDR-38/SDP-55/SDP-58 AV processors/receivers. Control via RS-232 (38400bps 8N1) or TCP/IP (port 50000). All commands use byte frame <St> <Zn> <Cc> <Dl> <Data> <Et> with St=0x21, Et=0x0D. AV implements virtual RC5 IR commands via 0x08 to simplify protocol; full RC5 code set documented for power/transport/zone control.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 50000
serial:
  baud_rate: 38400
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
auth:
  type: none  # inferred: no auth procedure in source

Traits

- powerable    # inferred from RC5 Power On/Off, Standby
- routable     # inferred from source select / HDMI output switching
- queryable    # inferred from query commands returning state
- levelable    # inferred from volume, bass, treble, balance, sub trim

# UNRESOLVED: many block-set commands (0x28, 0x29, 0x2A-0x33) expose a large
# composite payload of settable parameters. They are represented as block
# actions above; per-field variables not enumerated separately because the
# source documents them only as positional bytes inside the block payload.

Events

# Source states: "the AV may send messages at other times" - the device pushes
# state-change notifications (display, decode mode) using the same response
# frame format whenever a front-panel or IR input alters state.
- id: state_change_message
  description: Unsolicited status update frame emitted when state changes due to front-panel buttons or IR remote.
  frame_format: "21 <Zn> <Cc> 00 <Dl> <Data...> 0D"
  source: "State changes as a result of other inputs" section

Macros

# UNRESOLVED: source documents no canned multi-step sequences.

Safety

confirmation_required_for:
  - restore_factory_defaults    # source requires 0xAA 0xAA confirmation pattern
  - save_secure_backup          # source requires 0x55 0x55 + 4-byte PIN confirmation
  - restore_secure_backup       # source requires 0x55 0x55 + 4-byte PIN confirmation
  - reboot                      # source requires "REBOOT" ASCII confirmation payload
interlocks:
  - "Commands 0xF0-0xFF are reserved for test functions and must never be used."
  - "Tuner-specific commands return 0x85 (Command invalid at this time) when the corresponding source is not selected."
  - "Setup-menu-blocking commands return 0x85 while the OSD setup screen is displayed."
# UNRESOLVED: no voltage/current/power interlocks stated.

Notes

Control must be enabled before use: front-panel hold DIRECT 4s for RS232, or OSD General Setup → Control = On for RS232 or IP.
IP control over TCP port 50000 of the unit's IP (set in Network Settings).
All transmissions framed <St=0x21> <Zn> <Cc> <Dl> <Data> <Et=0x0D>; responses add an <Ac> (answer code) byte after <Cc>.
Answer codes: 0x00 OK, 0x82 zone invalid, 0x83 command not recognised, 0x84 parameter not recognised, 0x85 command invalid at this time, 0x86 invalid data length.
AV responds within 3 seconds; RC may pipeline further commands before previous response received.
Zone numbers: 0x01 = master (Zone 1), 0x02 = Zone 2. Zone-less commands target Zone 1.
The protocol exposes large block-set commands (0x28 input config, 0x29 general setup, 0x2A-0x33 speaker/network/HDMI/zone/engineering). Each block has a fixed positional byte layout in the source; spec models them as single block actions, with semantics for each byte in the source rather than enumerating per-field actions.
AMX Duet DDDP supported: device responds to "AMX\r" with AMXB<Device-SDKClass=Receiver><Device-Make=JBL>...\r. Control 4 SDDP also supported (no specific wire command — discovery-only).
Many configuration parameters carry both positive (0x00-0x0C, 0x00-0x14) and negative (0x81-0x8C, 0x81-0x94) ranges using the high bit as a sign flag.
