Aurora Dxci4Lhdmig2 Control Spec

Summary

Aurora DXM G2 Series HDMI matrix router controlled via RS-232C serial. Supports input-to-output routing, presets, per-port baud configuration, serial pass-through transmit/receive, HDCP/DVI/hot-plug output mode control, and firmware/route/status queries. Main control port is RS-232 (DB-9 female); recommended serial config is 115200 8N1.

Transport

protocols:
  - serial
serial:
  baud_rate: 115200  # source: "Recommended baud rate is 115k 8N1" / "Max 115kbps"
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control not stated in source
auth:
  type: none  # inferred: no auth procedure in source

Traits

- routable   # inferred: route commands present (!Rxtoz, !RTx1 x2 x3)
- queryable  # inferred: query commands present (?BRIN, ?R, ?FM0, etc.)

Actions

# Protocol notes: commands prefixed "!" = command, "?" = query (case sensitive).
# All command strings terminate with <CR> (0x0D). Responses prefixed "~" echo the
# command in same case. Wait >= 250ms between commands (firmware v2.2.6+).
# Port numbers x = 1-32 unless noted; multiple ports separated by space.

Variables

# UNRESOLVED: no continuous-level parameters (volume/gain/brightness) documented in source.
# Baud rate per port is settable via discrete command but is a configuration value, not a runtime level.

Events

# Unsolicited serial pass-through: when an attached DXW-2 wall plate (or other serial
# device) sends data via a receive-enabled input port, the matrix forwards it wrapped:
# ~RSIN{x}TX{nn}{s}<CR>
# Example: ~RSIN1TX05~BP1<CR><CR>  (button 1 press on DXW-2 at input 1)
# UNRESOLVED: no other unsolicited notification types documented in source.

Macros

# UNRESOLVED: no multi-step sequences explicitly documented in source.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no safety warnings, interlock procedures, or
# power-on sequencing requirements.

Notes

• Command prefix ! = command, ? = query, ~ = response (all case sensitive — response matches command case).
• <CR> = carriage return (0x0D / decimal 13). Terminates all commands and responses.
• Timing: wait at least 250ms between commands (firmware v2.2.6 and above).
• Baud rate selectable via front panel menu and via !BRab... commands; per-port configuration supported on input and output cards independently.
• Serial pass-through: byte count nn must be two ASCII digits (zero-padded); hex escapes (%0D in Aurora URL-encoded form, or 0x0D on other systems) count as 1 byte.
• DB-9 female connector: pin 2 = TX, pin 3 = RX, pin 5 = GND.
• LAN port documented as "Future Use" — if LAN needed, source recommends Nugget Serial on the RS-232 port.
• Firmware query commands do not work on analog cards.
