Onkyo TX-DS787 Control Spec

Summary

Onkyo TX-DS787 AV receiver controlled over RS-232C using ISCP (Integra Serial Control Protocol, documented in "Integra Serial Communication Protocol for AV Receiver" v1.15). Spec covers the commands the source marks supported for the TX-DS787/DTR-7.1 column: system power, muting, master volume, input/record-out selection, Zone2 source selection, listening modes, late night, Re-EQ/Academy filter, tuner/presets/RDS, display and dimmer, plus RI-bus pass-through control of connected CD/tape devices.

Transport

protocols:

# Framing (ISCP over RS-232C, from source section 1.1):
#   Controller -> Device: "!" + unit-type char "1" (Receiver) + 3 command chars +
#     parameter chars + end char [CR] (0x0D) or [LF] (0x0A) or [CR][LF].
#     Example: !1PWR01[CR]
#   Device -> Controller: "!" + "1" + ISCP message + [EOF] (0x1A).
#     Example (power standby): !1SST00[EOF]  (example verbatim from source)
#   3-wire RS-232C, 9-pin female D connector: pin 2 = transmit, pin 3 = receive,
#     pin 5 = signal ground. Use a straight-through cable.
# Note: source also documents eISCP over Ethernet (TCP port 60128 default) but only
#   for network-capable models; TX-DS787 is not in those model columns.

Traits

# powerable: inferred from PWR00/PWR01 commands
# routable: inferred from SLI/SLR/SLZ input selection commands
# queryable: inferred from QSTN query commands returning state
# levelable: inferred from MVL volume set/up/down commands
- powerable
- routable
- queryable
- levelable

Actions

# All command values are the ISCP message (3 command chars + parameter chars).

  # PRS response "01"-"28" hexadecimal = preset 1-40
# UNRESOLVED: tuning-frequency query (TUNQSTN) not supported on TX-DS787 per source support matrix

Variables

# No settable parameters beyond the discrete/parameterized actions above.
# UNRESOLVED: none identified in source

Events

# Event Notice Communication (source section 2.3): if system status changes,
# the Receiver notifies the Controller by sending the new current status as an
# unsolicited ISCP status message (e.g. "SLI03" wrapped in "!1"...[EOF] framing).
- id: status_change_notice
  type: string
  description: Unsolicited ISCP status message sent whenever receiver status changes

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 for serial control.

Notes

• Command timing: receiver responds to a command with a status message within 50 msec; if no response within 50 msec, "the communication has failed" (source section 2.1).
• Question communication: send a Question Message (e.g. "SLIQSTN") to get current status; receiver responds with a status message (e.g. "SLI03") (source section 2.2).
• Protocol is point-to-point between one third-party controller and the receiver (source section 2).
• ISCP message structure: 3 fixed command characters + variable-length parameter characters (source section 1).
• RI commands (CCD/CT1/CT2 groups) operate RI-bus-connected Onkyo devices (CD player, cassette decks) through the receiver, not the receiver itself.
• SLZ (Zone2 selector) on TX-DS787: source footnote "*1: only works when main is ON". Zone2 power/mute/volume serial commands (ZPW/ZMT/ZVL) are NOT supported on TX-DS787 per the source support matrix.
• TUN frequency parameter: 5 digits — FM as nnn.nn MHz, AM as nnnnn kHz.
• Volume range for TX-DS787 is 0-100 ("00"-"64" hex); the 0-80 ("00"-"50" hex) variant applies to other models. Presets: 1-40 ("01"-"28" hex).
• RDS/PTS/TPS commands apply to RDS-equipped models; source marks them supported for TX-DS787.
• Firmware version check (source "Version Check" section) is a front-panel procedure (DISPLAY + STANDBY/ON), not a serial command.
• Source document covers many Onkyo/Integra models; only rows marked "Yes" in the "TX-DS787 DTR-7.1" column were included. eISCP/Ethernet section applies to network models only, not TX-DS787.

matched_actions: 152
action_count: 152

summary: "All 152 spec actions map to TX-DS787=Yes source rows; ISCP transport parameters (9600/8/N/1, 3-wire RS-232C, framing) verbatim in source. (7 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "Zone2 power/mute/volume/tone/balance commands (ZPW/ZMT/ZVL/ZTN/ZBL) and Net-Tune, XM, SIRIUS, HD Radio, memory setup, tone per-channel, sleep, trigger, and HDMI-era commands are marked unsupported for TX-DS787 in the source and are omitted. Zone2 selector (SLZ) is supported."
- "tuning-frequency query (TUNQSTN) not supported on TX-DS787 per source support matrix"
- "none identified in source"
- "no multi-step sequences described in source"
- "source contains no safety warnings, interlock procedures, or"
- "firmware version compatibility not stated in source"
- "RDS RT information response payload format not specified for TX-DS787"
