Aurora DTX-AMP25-M RS-232 / IP control commands

Summary

Aurora DTX-AMP25-M Dante/AES67 audio amplifier with Line In. This spec covers RS-232 serial control: volume level, audio source select, network parameter setting, and a set of device status queries. RS-232 connector is a 3.81mm euro style block labelled TX, RX, GND.

Transport

protocols:
  - serial
serial:
  baud_rate: 9600
  data_bits: 8
  parity: none
  stop_bits: 1
  # flow_control: UNRESOLVED: not stated in source
auth:
  type: none  # inferred: no auth procedure in RS-232 protocol section of source

Traits

- levelable   # inferred from Set Volume Level command (!**VOLUMEx, 0-40)
- queryable   # inferred from multiple query commands returning device state

Actions

# Commands use ASCII with <cr> terminator. Query prefix "?", set prefix "!".
# Device ack prefixed "~". LITERAL "**" IS PAYLOAD: source shows "**" in both
# command strings AND device response strings (e.g. ~**VOLUME12<cr>). Responses
# carry no markdown → "**" = verbatim protocol token. Kept per population policy.

Notes

RS-232 connector is a 3.81mm euro style block labelled TX, RX, GND.
Protocol section explicitly states "All commands are sent at 9600 baud 8N1". General unit defaults (115K baud, auto IP) noted elsewhere do not apply to RS-232 command channel.
Web Setup page at http://<ip>/setup = HTTP management interface (volume, IP, Dante stream, audio source), default user/pass "admin". Distinct from RS-232 control; NOT covered here.
"?**DANTE_IS_ACTIVATER" in source Query Dante Activation row = typo for ?**DANTE_IS_ACTIVATED (per header + response).
Literal ** retained verbatim in every command/response. Source documents ** inside device response strings (e.g. Response: ~**VOLUME12<cr>) — hardware responses carry no markdown, so ** = protocol framing token, not bold markup. Unclosed ** → framing byte. Driving device without ** would likely fail command recognition. Kept verbatim; no normalization.
