Onkyo TX-DS898 Control Spec

Summary

Onkyo TX-DS898 AV receiver. ISCP (Integra Serial Control Protocol) over RS-232C (9600 baud, 8N1, no flow control, DB9 straight-thru). The source also describes eISCP over TCP, with protocol-wide default port 60128 and configurable ports 49152-65535; Ethernet applicability to TX-DS898 is UNRESOLVED. Authentication is UNRESOLVED because the source does not state an authentication policy. Controls: system power, muting, master volume, input selector, RECOUT selector, listening mode, late night, dimmer, sleep, tuner, preset, display mode, OSD menu, Re-EQ, and RI-connected CD/Tape1/Tape2/DAT/MD/CDR/DVD devices and graphics equalizer. Existing Zone2 definitions are retained, but their TX-DS898 applicability and model-specific ranges are UNRESOLVED.

# UNRESOLVED: TX-DS898 Ethernet applicability is not established by the supplied source.
# Protocol-wide eISCP documentation specifies TCP port 60128 by default,
# configurable from 49152 through 65535; these are not established TX-DS898 defaults.
# UNRESOLVED: no eISCP header-only protocol block emitted; defer to a separate protocol group if needed.
auth:
  type: UNRESOLVED  # Source does not state an authentication policy.

Traits

powerable:
  - inferred from PWR command ("00"=Standby, "01"=On)
queryable:
  - inferred from QSTN suffix used throughout
levelable:
  - inferred from MVL volume range 0x00-0x64
routable:
  - inferred from SLI input selector and SLR RECOUT selector

Variables

# Front tone (TFR), Front Wide (TFW), Front High (TFH), Center (TCT), Surround (TSR),
# Surround Back (TSB), Subwoofer (TSW) are documented protocol-wide but TX-DS898
# column shows "No" across the board - not emitted.
# UNRESOLVED: Zone2 tone (ZTN) applicability to TX-DS898 is not established
# by the supplied protocol-wide Zone2 table.

Events

# Receiver sends unsolicited Status Message to controller when status changes.
# Example: user changes input on receiver -> receiver sends "SLI03" to controller.
# Receiver responds to a command within 50msec.
# RS-232C device-to-controller example ends with [EOF] (0x1A).
# Controller-to-device RS-232C commands end with [CR], [LF], or [CR][LF].
# UNRESOLVED: the RS-232C standby example uses SST00 rather than PWR00;
# this source inconsistency does not establish a separate SST query or action.
# Protocol-wide Ethernet documentation requires a message interval >50msec
# and continuous connection for status notices; TX-DS898 Ethernet applicability
# is UNRESOLVED.

Macros

# No explicit multi-step macro sequences defined in source.
# Receiver responds to a command within 50msec.
# Controller-to-device RS-232C end character: [CR], [LF], or [CR][LF].
# Protocol-wide eISCP end characters: [EOF], [EOF][CR], or [EOF][CR][LF],
# depending on model. Ethernet message interval must be >50msec.
# UNRESOLVED: TX-DS898 Ethernet applicability and eISCP end-character variant.

Notes

ISCP message format: !1{command}{parameter}[CR] for controller-to-device RS-232C messages, where !1 = start character + unit type ("1" for Receiver). Command end character: [CR], [LF], or [CR][LF]. The source device-to-controller RS-232C example ends with [EOF] (0x1A). Its standby example uses SST00; the relationship to the documented PWR status command is UNRESOLVED and does not justify an invented SST command.

The protocol-wide eISCP/Ethernet format has a header beginning with ASCII ISCP, followed by Header Size and Data Size as big-endian fields, Version 0x01 and Reserved 0x000000. Current Header Size is 0x00000010, but implementations must account for the transmitted header size. Data Size is the size of the following ISCP data. The data end character is [EOF], [EOF][CR], or [EOF][CR][LF], depending on model. TX-DS898 Ethernet applicability and its eISCP terminator variant are UNRESOLVED.

Hardware: 3-wire RS-232C, DB9 female (pin 2=TX, pin 3=RX, pin 5=GND). Straight-thru cable. 9600/8/N/1, no flow control. The source's protocol-wide Ethernet section specifies default port 60128, configurable 49152-65535 via the receiver setup menu followed by entering standby; one TCP connection at a time, held continuously for unsolicited status notifications, and message interval greater than 50msec. These Ethernet details do not establish Ethernet support or defaults for TX-DS898. Authentication is UNRESOLVED; absence of an authentication procedure in the source is not evidence of authentication type none.

The TX-DS898 support column ("TX-DS898 DTR-8.2") shows Yes for PWR/AMT/MVL/SLI/SLR/SLA/SLP/SLC/DIF display mode/DIM/OSD/LTN/Re-EQ RAS/LMD/TUN/PRS/RDS/PTS/TPS and supported RI-device rows for CCD/CT1/CT2/CEQ/CDT/CDV/CMD/CCR. DIF wrap-around uses parameter UP according to footnote *1. LMD 03 FILM is No for TX-DS898. The Cinema Filter RAS variant is No for TX-DS898; only the Re-EQ interpretation is supported. TUNQSTN and PRSQSTN are Yes for TX-DS898 and remain represented by their existing query actions. RDS/PTS/TPS are restricted to RDS models; the source limits RDS information on RBDS models to RT information. Regional applicability is UNRESOLVED.

The supplied RI DVD list documents the supported CDV parameter rows represented above, but does not document ANGLE. The MD list explicitly documents EJECT, so that supported parameter is retained. The CD display-mode parameter is D.MODE, including the period. Code and parameter are concatenated without a separator before applying the transport framing.

The supplied Zone2 tables are protocol-wide and have no TX-DS898 support column. They list two alternative ZVL ranges without a model mapping and an SLZ input list extending beyond TX-DS898 main-zone capabilities. Their TX-DS898 applicability, volume range and selector subset remain UNRESOLVED. The main-on footnote follows ZVL; the source does not establish a blanket main-on interlock for every Zone2 command. The existing Zone2 action and query ids are preserved without claiming model-specific confirmation.

Do not infer support for HDO/RES/ISF HDMI outputs, Audyssey (ADY/ADQ/ADV), Dolby Volume (DVL), TFR/TCT/TSR/TSB/TSW/TFH/TFW tone commands, SPA/SPB Speaker A/B, MEM, IFA/IFV information, TGA/TGB/TGC triggers, VOS, unsupported network/tuner functions, or SLI MULTI CH from protocol-wide descriptions. The 2003-08-22 revision 1.00 first edition explicitly includes TX-DS898.

Amendment clarification: the complete source supplied for this amendment explicitly documents CDV parameter ANGLE with Yes in the TX-DS898 column. The appended cdv_angle action represents it separately; the preserved original entry and note contain an outdated exclusion. The source also documents CCD 10, DISC.F, DISC.R, and DISC1 through DISC6 for TX-DS898. Appended actions retain the source's literal three-character Code in command; their parameter descriptions specify the suffix to concatenate without a separator. Zone2 additions represent protocol-wide documentation only, with TX-DS898 applicability UNRESOLVED. ZTN has its own condition: main is ON and Zone2 is powered or variable.
