Marantz NA-7004 RS-232 / IP control commands

Summary

Marantz NA-7004 Network Audio Player. Supports both RS-232C and Ethernet (TCP/IP telnet) control using an ASCII command protocol of the form COMMAND + PARAMETER + CR (0x0D) where COMMAND is 2 ASCII characters and PARAMETER up to 25 ASCII characters. Covers power, input source select, master volume, M-DAX, tuner (analog AM/FM and DAB), favorites, menu cursor, and network/USB/iPod direct playback control.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 23  # TCP port 23 (telnet), stated verbatim in source
serial:
  baud_rate: 9600
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow control not stated in source (procedural = "Non procedural")

Notes: Ethernet connector RJ-45 (10BASE-T/100BASE-TX), half duplex, 10/100 Mbps, max data length 135 bytes. RS-232C connector DB-9pin female (DCE, straight), pins 1=GND, 2=TxD, 3=RxD, 5=Common(GND), 4/6/7/8/9=NC. Tone step synchronization, half duplex, non-procedural, max 135 bytes. ASCII range 0x20–0x7F plus CR (0x0D) as terminator. RESPONSE to a request command must be sent within 200ms. After PWON, wait 1 second before sending next command.

Traits

traits:
  - powerable   # inferred from PWON/PWSTANDBY power commands
  - queryable   # inferred from PW?/SI?/TF?/TP?/TM?/PSMDA ?/FV ? query commands
  - levelable   # inferred from MV master volume commands
  - routable    # inferred from SI input source routing commands

Actions

# All commands terminate with CR (0x0D), shown here as <CR> per source convention.
# Each command verbatim from source COMMAND and PARAMETER list.

Variables

# Discrete settable parameters are represented as Actions above (PSMDA, TM,
# MV level, etc.). No additional continuous variables beyond MV documented.
# UNRESOLVED: source does not document a separate variable namespace.

Events

# Unsolicited EVENTs are identical in form to the Feedbacks listed above and are
# sent by the device when operated directly (state change from front panel etc.).
# See Feedbacks section. COMMAND is receivable also during EVENT transmission.

Macros

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

Safety

confirmation_required_for: []
interlocks:
  - "After PWON, wait 1 second before transmitting next COMMAND (source item K)."
  - "TF/TP commands cannot operate when INPUT source isn't TUNER."
  - "NS commands apply to Network/Rhapsody/Napster/USB/iPod Direct sources."
# UNRESOLVED: no further safety warnings, fault behavior, or error recovery
# sequences documented in source.

Notes

Model name appears as both "NA-7004" and "NA7004" in source; spec uses NA-7004.
Application terminal: RS-232C / Ethernet. Application model: NA-7004.
ASCII CODE usable range 0x20–0x7F plus CR (0x0D) as pause/terminator sign.
COMMAND is exactly 2 ASCII characters; PARAMETER up to 25 ASCII characters.
Special parameter ? = request command.
RESPONSE must be sent within 200ms of receiving the request COMMAND.
RESPONSE is sent for commands that have an EVENT counterpart; not needed for commands without EVENT (e.g. SV — though SV is not used on this device).
Master Volume minimum level parameter defines "99"; supports 0.5dB step using 3-char parameter (see master_volume_set description).
North America model adds the D.IN(USB)/D.IN(COAXIAL)/D.IN(OPTICAL) inputs in the SI row note; these are not separately enumerated as commands in the table and are marked as North-America-only.


Spec done. 68 actions enumerated (every distinct row from source tables). Both transports (TCP:23 + RS-232C 9600/8/N/1) populated verbatim. Auth inferred none. MVDOWN + full MV table marked UNRESOLVED — page 7 ref cut from extract.

```

## Known Gaps

```yaml
- "full MV (Master Volume) command table not present in source (referenced as \"see page 7 section J\" but table omitted). MVDOWN not documented verbatim. Channel volume, surround mode, and many AVR-style commands absent — this is a network audio player, not an AVR."
- "flow control not stated in source (procedural = \"Non procedural\")"
- "MVDOWN not documented verbatim in source. Full MV table referenced"
- "source does not document a separate variable namespace."
- "source documents no multi-step command sequences."
- "no further safety warnings, fault behavior, or error recovery"
- "firmware version compatibility not stated in source."
- "MVDOWN command and full MV command table missing from extracted source (page 7 J reference)."
- "voltage, current, power specs not in protocol document."
- "protocol version number not stated."
- "Network Standby mode is a front-panel setting, not a documented remote command."

# Discrete settable parameters are represented as Actions above (PSMDA, TM, # MV level, etc.). No additional continuous variables beyond MV documented. # UNRESOLVED: source does not document a separate variable namespace.

# Unsolicited EVENTs are identical in form to the Feedbacks listed above and are # sent by the device when operated directly (state change from front panel etc.). # See Feedbacks section. COMMAND is receivable also during EVENT transmission.

Safety

confirmation_required_for: [] interlocks: - "After PWON, wait 1 second before transmitting next COMMAND (source item K)." - "TF/TP commands cannot operate when INPUT source isn't TUNER." - "NS commands apply to Network/Rhapsody/Napster/USB/iPod Direct sources." # UNRESOLVED: no further safety warnings, fault behavior, or error recovery # sequences documented in source.

Notes

Model name appears as both "NA-7004" and "NA7004" in source; spec uses NA-7004.

Application terminal: RS-232C / Ethernet. Application model: NA-7004.

ASCII CODE usable range 0x20–0x7F plus CR (0x0D) as pause/terminator sign.

COMMAND is exactly 2 ASCII characters; PARAMETER up to 25 ASCII characters.

Special parameter ? = request command.

RESPONSE must be sent within 200ms of receiving the request COMMAND.

RESPONSE is sent for commands that have an EVENT counterpart; not needed for commands without EVENT (e.g. SV — though SV is not used on this device).

Master Volume minimum level parameter defines "99"; supports 0.5dB step using 3-char parameter (see master_volume_set description).

North America model adds the D.IN(USB)/D.IN(COAXIAL)/D.IN(OPTICAL) inputs in the SI row note; these are not separately enumerated as commands in the table and are marked as North-America-only.

Spec done. 68 actions enumerated (every distinct row from source tables). Both transports (TCP:23 + RS-232C 9600/8/N/1) populated verbatim. Auth inferred none. MVDOWN + full MV table marked UNRESOLVED — page 7 ref cut from extract. ## Provenance ```yaml source_domains: - heimkinoraum.de - marantz.com - raw.githubusercontent.com - github.com source_urls: - https://www.heimkinoraum.de/upload/files/product/IP_Protocol_AVR-Xx100.pdf - https://www.marantz.com/en-us/product/archive-network-audio-players/na7004/NA7004.html - https://raw.githubusercontent.com/Ericvf/RS232c-Tcp-Marantz/master/NA7004_PROTOCOL_V01.pdf - https://www.marantz.com/en-us/product/archive-network-audio-players/na-11s1/NA11S1.html - https://github.com/ChrisBrandhorst/node-marantz-ip-control retrieved_at: 2026-06-23T08:04:22.127Z last_checked_at: 2026-06-23T08:13:17.822Z ``` ## Verification Summary ```yaml verdict: verified checked_at: 2026-06-23T08:13:17.822Z matched_actions: 68 action_count: 68 confidence: medium summary: "All 68 spec actions matched verbatim in NA7004 source command table; transport (port 23, 9600 8N1) verified; bidirectional coverage complete.

MVDOWN not documented verbatim. Channel volume, surround mode, and many AVR-style commands absent — this is a network audio player, not an AVR." - "flow control not stated in source (procedural = \"Non procedural\")" - "MVDOWN not documented verbatim in source. Full MV table referenced" - "source does not document a separate variable namespace." - "source documents no multi-step command sequences." - "no further safety warnings, fault behavior, or error recovery" - "firmware version compatibility not stated in source." - "MVDOWN command and full MV command table missing from extracted source (page 7 J reference)." - "voltage, current, power specs not in protocol document." - "protocol version number not stated." - "Network Standby mode is a front-panel setting, not a documented remote command." ``` --- From the AI4AV catalog (https://ai4av.net) · ODbL-1.0
