Summary
The Blustream MV41 is an HDMI matrix switcher controllable via TCP/IP (Telnet) and RS-232 serial. Commands are plain ASCII strings terminated with a carriage return (\r). The unit also exposes a built-in web browser interface for control and configuration. The source document references model CMX88AB; this spec is applied to the MV41 per ingest request.

Notes
- Commands are plain ASCII terminated with a carriage return (
\r, hex0x0D). Some terminal programs use<CR>or0D. - Do not include spaces within commands unless required by the control program. Correct format:
OUT01ON(no spaces). - RS-232 pin assignment: Pin 2 = Tx, Pin 3 = Rx, Pin 5 = GND. A straight or null-modem cable may be required depending on the control device.
- Default IP address (when no DHCP server present): 192.168.0.200. Device ships with DHCP enabled.
- Web interface provides control and configuration via a built-in web server.
- IR hardware uses 5V.

**Self-check:**
- No voltage/current/power values invented ✓
- No port numbers assumed ✓ (marked UNRESOLVED)
- No baud rate assumed ✓ (57600 stated in source)
- `status: draft` ✓
- `declared_confidence: low` ✓
- YAML blocks valid ✓
- `entity_id` populated from input ✓
- UNRESOLVED markers present for all gaps ✓
**Note:** The source document is titled "CMX88AB Control Protocols" and references an 8×8 matrix, while the requested device is "MV41". The MV41 may be a different model with a different I/O count. The command set appears shared across Blustream matrix products, but this should be verified against the actual MV41 documentation.Spec generated above. Key flags:
- **Source/model mismatch**: Source doc covers CMX88AB (8×8 matrix); MV41 may have different I/O counts
- **TCP port**: Not stated — marked UNRESOLVED
- **Auth**: Credentials stated (`blustream`/`1234`) but unclear if they apply to Telnet or only the web UI
- **Serial config**: Fully specified — 57600/8N1/no flow control
- **14 commands** documented in the command reference table
