Denon Electronics Rcdn9 Control Spec

Summary

Network control protocol (Ver.1.0.0) for the Denon DRA-N5 / RCD-N8, carried over Ethernet (RJ-45, 10/100BASE-TX) on TCP port 23 (telnet). ASCII command set covering power, master volume, mute, input source select, sleep timer, timers/clock, tone (bass/treble/balance), SDB, source direct, favorites, menu/favorite cursor control, analog tuner, DAB tuner, network/USB/iPod browse control (NS), and CD transport control (N8 only).

Transport

protocols:
  - tcp
addressing:
  port: 23  # stated: "Communication port : TCP port 23 (telnet)"
auth:
  type: none  # inferred: no auth procedure in source

Traits

# - powerable   (PWON/PWSTANDBY present)
# - routable    (SI input source select commands present)
# - queryable   (PW?, MV?, MU?, SI?, SLP?, TS?, TO?, PS sub-queries present)
# - levelable   (MV, PSBAS, PSTRE, PSBAL level controls present)
traits:
  - powerable  # inferred from power command examples
  - routable  # inferred from input source select commands
  - queryable  # inferred from query command examples
  - levelable  # inferred from volume/tone level commands

Actions

# All commands terminated with CR (0x0D). ASCII 0x20-0x7F only. Max data length 135 bytes.
# <CR> omitted from command strings below; append 0x0D when transmitting.
# Notes: wait 1 second after PWON before next command. TF/TP '*' params
# inoperative unless input source is TUNER. CD (BD), analog tuner, DAB are N8 only.

Events

# Device sends EVENT messages (same form as COMMAND) unsolicited when operated
# directly and state changes. Documented EVENT set: PW, MV, MU, SI, SLP, TS
# (ONCE/EVERY), TO, CLK, PS (BAS/TRE/BAL/SDB/SDI), FV (favorite name),
# TF/TP/TM (analog tuner + DAB), NSA/NSE (display info), BD (CD status and
# per-operation acknowledgements with answer codes 0-3).
# Every command with a matching EVENT also answers its request form (? + CR)
# as a RESPONSE within 200ms.
- id: state_change_event
  description: "Unsolicited EVENT on direct operation/state change; form identical to COMMAND (see Feedbacks for per-command payloads)"

Macros

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

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no safety warnings or interlock procedures;
# only timing constraint found is waiting 1 second after PWON before next command

Notes

• Command structure: COMMAND (2 ASCII chars) + PARAMETER (up to 25 ASCII chars) + CR (0x0D). Usable ASCII 0x20-0x7F; CR acts as pause/terminator only. Max communication data length 135 bytes.
• Connector: RJ-45, 10BASE-T/100BASE-TX, half duplex, 10/100 Mbps, TCP port 23 (telnet). Cross cable direct to PC or straight cables via HUB.
• RESPONSE must be sent within 200ms of receiving a request command. Commands are receivable during EVENT transmission.
• Wait 1 second after transmitting PWON before the next command.
• Master volume parameter "00" = minimum level; volume 00-60 by ASCII in 1dB steps.
• Network Standby mode must be set to "Network On" (SETUP > Network > Network Standby) for network control while in standby.
• DHCP/IP/Subnet/Gateway configured on-device via SETUP menu (Network > Settings). Proxy must be Off. DNS fields unused.
• Model/regional differences: CD, FM, AM (JP), DAB, AUXA, AUXC inputs are N8 only; LASTFM is E2 only; PANDORA and SIRIUSXM are NA only.
• TF/TP/TM '*' parameters inoperative when input source is not TUNER.
• NS9F and NS9G both labeled "Start Fast Forward" in source (9G likely fast reverse — not stated). NS97/NS98 function labels blank in source.
• CD (BD command set) answer codes: 0 = command OK, 1 = invalid command, 2 = invalid (specified track/group/title/chapter does not exist), 3 = order track none. Status codes 0-G cover standby through scan play; play mode codes 1-; cover NORMAL through REPEAT FOLDER.
• Protocol document version Ver.1.0.0 (12 Oct 2012); application terminal Ethernet Rev 8.0.0.
• Device name "Rcdn9" from ingest metadata does not appear in source; source application models are DRA-N5 and RCD-N8. Known protocol RS-232C in ingest metadata contradicts source (Ethernet telnet only; no serial port spec in source).

summary: "All 147 spec actions map to literals in the COMMAND/PARAMETER tables of the Denon SYSTEM protocol source; transport matches verbatim; no extras omitted. (9 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "input device name \"Rcdn9\" does not match source application models \"DRA-N5/RCD-N8\"; source covers DRA-N5/RCD-N8 only"
- "firmware version compatibility not stated in source"
- "no RS-232 serial configuration found in source despite RS-232C being flagged as known protocol; source specifies Ethernet only"
- "function description blank in source\""
- "no multi-step sequences described explicitly in source"
- "source contains no safety warnings or interlock procedures;"
- "no serial (RS-232C) electrical/port configuration found in source despite ingest metadata claiming RS-232C"
- "NS97/NS98 function descriptions blank in source"
- "NSE parameter example frames omitted from source (NSA example format applies)"
