Notes

Protocol: Binary message stream over TCP. Message envelope: DWORD messageType + DWORD length + BYTE[data] (8-byte min, 8000-byte max). Three message types: MDSM_REMOTEPROCEDURE_REQ(3), MDSM_REMOTEPROCEDURE_RSP(4), MDSM_NOTIFY(5).

Heartbeat: Send MESSAGETYPE_OIP_KeepAlive every 5s. If CCU sees no message for 15s, it closes connection.

Timing: Command response max 10s; typical <0.5s. Remote function request must wait for response before sending next request (CCU can handle 2 pending).

System modes: Init, Config, Congress, Maintenance, Download, Down — per-function availability varies.

Error codes: RFSE_BADFUNCTIONID(0x2A95), RFSE_ALLOCFAILED(0x2A98), RFSE_NOACCESSPERMISSION(0x2A9B) for RFS; app-specific codes in Appendix C.

Upgrade pass additions: Added missing Delegate Database (DB) chapter (DB_C_START_APP, DB_C_STOP_APP, DB_C_MAINT_CCU, DB_C_DOWNLOAD_CCU, DB_C_CLEAR_CCU, DB_C_CCU_APPLY_ONE), SI monitoring pair (SI_C_START_MON_SI, SI_C_STOP_MON_SI), MM_C_STOP_MON_MM, MM_C_NBK_REMOVE, MM_C_NBK_CLEAR, deprecated IN_C_SIGNAL_CCU, SC_C_GET_CCU_CONFIG (deprecated), SC_C_LOW_BATTERY_REQ, and feedbacks MM_C_SPK_CLEAR_ON_PC, MM_C_NBK_CLEAR_ON_PC, MM_C_RTS_CLEAR_COMMENT_ON_PC.

Note: Device name in input (DCMNWAP) does not match source (DCN NG). Source describes a congress/conference system with Central Control Unit. Compatible model should be confirmed against actual product listing.

Added 12 missing actions + 3 missing feedbacks. DB chapter was biggest gap (entire §4 of source absent). Preserved all existing IDs/shapes.

summary: "Every SC/SI/DB/MM/CC/IN/VT/AT/LD/MD/IC action and feedback in the spec maps 1:1 to a documented remote function or notification (and matching Appendix B define) with matching parameter shapes; transport port 9451 confirmed verbatim. (7 unresolved item(s) noted in Known Gaps.)"
```

## Known Gaps

```yaml
- "compatible_with.models should be verified against actual product name — source describes DCN NG system; input specified DCMNWAP which may be a different variant"
- "remove section if not applicable"
- "no explicit multi-step macros described - remove section if not applicable"
- "safety warnings/interlocks not found in source - Open Interface license (LBB4187/00) required per source §1.2"
- "compatible_with.models — source is \"DCN Next Generation\" not \"DCMNWAP\"; actual model match unknown"
- "RS-232 serial transport — source mentions RS-232 signal definitions in table but only describes TCP/IP Ethernet control — no serial configuration stated"
- "auth credentials — Open Interface license required but no password/token described in source"
```
