Marantz VC6001 (North America) control commands

Summary

AV Surround Receiver supporting RS-232C and Ethernet (TCP/IP telnet) control. Full duplex ASCII command protocol with 2-character command codes and up to 25-character parameters terminated by CR (0x0D). Supports multi-zone power, volume, input routing, surround mode, video processing, tuner, and USB/iPod/Bluetooth playback control.

Variables

# UNRESOLVED: many PS (parameter) commands act as settable variables but are documented
# as action-style commands. Full variable enumeration pending analysis of
# parameter ranges and response formats for all PS sub-commands.

Events

# The device sends EVENT messages when state changes occur without a controller request.
# Event form matches COMMAND form. Events sent within 5 seconds of state change.
# UNRESOLVED: complete event catalog not explicitly enumerated in source.
# Known events: power state changes, input source changes, surround mode changes,
# channel volume changes, mute state changes - all return as EVENT after direct device operation.

Macros

# UNRESOLVED: no explicit multi-step macros described in source.
# The document describes command timing requirements (50ms intervals, 1s after PWON)
# that may constitute implicit sequences.

Safety

confirmation_required_for: []
interlocks:
  - description: "Send power on command (PWON) then wait 1 second before transmitting next command"
    reference: "Volume command note section, item J"
  - description: "Send commands at 50ms or more intervals"
    reference: "COMMAND section"
# UNRESOLVED: no explicit safety warnings, interlock procedures, or power-on sequencing
# beyond timing notes above

Notes

Protocol is half-duplex on both RS-232 and Ethernet
Maximum command/data length: 135 bytes
ASCII range: 0x20–0x7F; CR (0x0D) used only as terminator
Volume uses 0.5dB steps encoded as 2 or 3 ASCII characters
Channel volume parameter range 38–62 ASCII for most channels (50=0dB), subwoofer 00,38–62
Master volume range 00–98 ASCII (80=0dB, 00=--- minimum)
EVENTS sent within 5 seconds of state change; RESPONSES sent within 200ms of request
Command reception continues during EVENT transmission (non-blocking)
When input source changes, channel volume and surround mode return as EVENT
Channel volume does not re-return if already at same value before/after input change
RESPONSE not needed for commands that already generate an EVENT (e.g., SV command)
Some commands are model-specific (noted with asterisks in source)
Auro-3D commands only available with Auro-3D upgrade
HD Radio / HDRADIO / PANDORA / SIRIUSXM / SPOTIFY / LASTFM are North America model only
