EZCOO MX44-HAS2 4x4 HDMI Matrix Control Spec

Summary

4x4 HDMI matrix switcher with RS-232 and IP (browser/HTTP) control. Supports input-to-output routing, external audio enable/disable per output, stream control, EDID management, and factory reset. Commands are ASCII strings terminated with Enter.

Transport

protocols:
  - serial
  - tcp   # inferred: "IP control" mentioned; only browser access documented, no raw TCP port stated
  - http  # browser-based control documented in source ("begin with http://")
addressing:
  base_url: "http://{ip_address}"  # source: type device IP in browser, begin with http:// (IP obtained via EZG HIP)
  port: null  # UNRESOLVED: TCP port not stated in source
serial:
  baud_rate: null  # UNRESOLVED: baud rate not stated in source
  data_bits: null  # UNRESOLVED: not stated in source
  parity: null  # UNRESOLVED: not stated in source
  stop_bits: null  # UNRESOLVED: not stated in source
  flow_control: null  # UNRESOLVED: not stated in source
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - routable       # inferred: input/output routing commands present

Feedbacks

# UNRESOLVED: source does not document response formats for query commands
# EZSTA returns system status but format not specified
# EZG HIP returns IP address but format not specified

Variables

# UNRESOLVED: no settable parameters beyond discrete actions documented in source

Events

# UNRESOLVED: no unsolicited notification mechanism documented in source

Macros

# UNRESOLVED: no multi-step sequences documented in source

Safety

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

Notes

• All commands require Enter (carriage return / newline) terminator.
• IP control accessible via web browser using device IP with http:// prefix (device IP obtained by sending EZG HIP over RS232). Actual TCP command port for programmatic control not documented.
• EDID list and additional help available by sending EZH to the device.
• Output parameter 0 means ALL outputs in routing, audio, and stream commands.

Changes vs on-disk: added `http` protocol + `addressing.base_url` (source states browser + `http://`), bumped revision 2, updated Summary/Notes wording. All 13 source commands already covered — none added. Ports/baud still UNRESOLVED (not in source).
