Summary
The Aurora DXM 884 G4 is an HDMI/HDBaseT modular matrix switcher (DXM-G4 Series) with hot-swappable input/output daughter cards. It is controllable via a bidirectional RS-232C serial port and TCP/IP over Ethernet (socket server) using an ASCII command protocol. This spec covers the full documented RS232/IP command catalogue: video/audio routing, EDID management, scene save/recall, HDCP, per-card power, network and serial configuration, and system queries including a JSON status endpoint.
Transport
protocols:
- tcp
- serial
addressing:
port: 1001 # Socket Server port (TCP control), stated in source
serial:
baud_rate: 115200 # default; source states configurable range 9600~115200
data_bits: 8
parity: none
stop_bits: 1
flow_control: null # UNRESOLVED: flow control not stated in source
auth:
type: none # inferred: no auth/login procedure in the RS232/IP command protocol
Notes:
- Default IP address:
192.168.88.229(stated). - RS-232 connector: 3-pin Phoenix female — PIN 1: TX, PIN 2: GND, PIN 3: RX.
- A separate WEB server (default port 80) provides GUI management with default credentials User
user/ Password123456; this is distinct from the ASCII socket/serial control protocol. - Ethernet protocols supported: ICMP, ARP, IP, TCP, UDP, DHCP, HTTP; LAN 10/100BaseT half/full duplex.
Traits
traits:
- powerable # CPOWER card power on/off commands present
- routable # video/audio/UART/EDID routing commands present
- queryable # many query commands returning state present
Actions
# Framing convention (from source legend):
# > = Command line prefix
# # = Query line prefix
# < = Response line prefix
# <CR> = carriage return, 0x0D (13 decimal), line terminator
# Command/query prefixes appear verbatim in the source ASCII-string column.
# NOTE: whether the leading > / # byte is transmitted on the wire vs. being a
# documentation marker is not unambiguously confirmed - verify against a live
# device. Responses ( < ) are received, not sent.
# Audio suffix convention: V = Internal audio, E = External audio.

Variables
# All settable parameters (IP, subnet, gateway, port, DHCP, serial config, sync,
# sync mode, language, scene name, web display, HDCP, card power, HDMI/DVI mode,
# credentials) are expressed as discrete Actions above. No continuous/level
# variables are documented in the source.
Events
# UNRESOLVED: no unsolicited push notifications documented in source. The JSON
# status endpoint supports a `mark` (status update version) for polling, but no
# asynchronous event broadcast is described.
Macros
# UNRESOLVED: no multi-step command sequences explicitly documented in source.
Safety
confirmation_required_for: []
interlocks: []
# UNRESOLVED: no explicit safety warnings, interlock procedures, or power-on
# sequencing requirements found in the source. Note: SYS-RESET (factory reset)
# and SOF-RESTART (restart) are destructive/system-level - flag for operator
# confirmation at integration time even though source states no interlock.
Notes
- Command framing legend (source line 93):
>= Command,#= Query,<= Response,<CR>= 0x0D carriage return. Direction prefixes appear in the source ASCII-string column; verify against a live device whether the leading>/#byte is transmitted. - Same ASCII command set applies over both RS-232 and the TCP socket server (port 1001).
- Default serial: 115200 8N1; configurable baud 9600–115200, data bits 8/9, stop 1/1.5/2, parity None/Odd/Even via the
UARTcommand. - Audio routing uses V (Internal audio) / E (External audio) suffixes on input/output identifiers.
- Bidirectional RS-232 passthrough routing is point-to-point only (CUART command); HDBaseT cards also support RS232 passthrough (SEND-CU command).
- Matrix is modular; daughter-card types and counts vary (query via #RCID, matrix type via #M0 returning MVP-8C / MVP-16C / MVP-32C).
- WEB server (port 80) is a separate GUI management interface with default credentials
user/123456; the documented ASCII control protocol requires no login.
