Denon / Marantz AVR
Controls Denon and Marantz AV receivers using the ASCII command set they share (PWON, MV50, SIMPLAY). It keeps a persistent connection open, so changes made at the front panel are reported back.
Connection
Section titled “Connection”Two transports, both speaking the same ASCII protocol:
- Network — Telnet on TCP port 23.
- RS-232 serial — 9600 baud, 8N1.
The connection stays open and the receiver pushes state as it changes, so front-panel and remote-app adjustments show up without polling. Network units are discovered over SSDP.
- Connection —
networkorserial. - For network: host and port (default 23).
- For serial: serial port and baud (9600).
What it can do
Section titled “What it can do”| Command | What it does |
|---|---|
power_on / power_off | Turn the receiver on or off |
set_volume | Set the master volume (0–98) |
mute_on / mute_off | Mute or unmute |
set_input | Select an input (MPLAY, BD, TV, CD, GAME) |
raw | Send a raw ASCII command |
Reports power, volume, mute, and the current input as state. It implements input-source discovery, so it exposes the receiver’s real input list — including any inputs you’ve renamed on the unit.
