AI4AVSummary
This spec covers the Bosch DCN NG (Digital Congress Network Next Generation) Open Interface, a binary message-based remote-control protocol exposed by the DCN-CCU2 and DCN-CCUB2 Central Control Units over TCP/IP on port 9451. Third-party controllers issue remote function calls to manage congress hardware (delegate/chairman units, microphones, voting, interpretation booths, cameras, attendance registration, intercom, message distribution, text displays) and receive asynchronous update notifications. The interface must be licensed (LBB4187/00) and enabled via the Download and Licensing Tool shipped on the DCN DVD.
Transport
protocols:
- tcp

# UNRESOLVED: MESSAGETYPE_OIP_Dcn value not stated; other OIP types in 0x00447xxx range
framing: binary_little_endian

Notes: UTP/STP cable; max ~100m between CCU and remote controller (repeater for longer). 16-byte heartbeat frame (MESSAGETYPE_OIP_KeepAlive 0x00447027). Error response frame is 24 bytes (MESSAGETYPE_OIP_ResponseProtocolError 0x00447020).
Traits
# - queryable (many GET functions: SC_C_GET_CCU_VERSIONINFO, MM_C_GET_SETTINGS, SI_C_GET_EXT_CONTACT, etc.)
# - routable (MM_C_SET_MICRO_ON_OFF, IN_C_DESK_UPDATE, CC_C_SET_CAMERA_ASSIGNMENT - input/output routing)
# - levelable (SI_C_SET_MASTER_VOL 0..25, SI_C_SET_MICROPHONE_GAIN 0..15)
queryable: true
routable: true
levelable: true
Actions
# Each action corresponds to one Remote Function defined in the source.
# `command` is the 16-bit wFnId documented in Appendix B of the source, expressed as
# a hex WORD. On-wire payload additionally uses byDcnMsgType=0x03 (MDSC_REMOTEPROCEDURE_REQ)
# and byMessageTypeHeader=0x43 per §2.2.3.3. Parameter `params` mirror the C struct
# fields documented in the corresponding section.

Notes
- Protocol is a binary, little-endian, message-based RPC over a single TCP/IP stream on port 9451. The remote controller opens the connection; the CCU listens. No authentication handshake is documented —
auth.type: noneis inferred from the absence of any login procedure in the source. - Message frame (Ethernet layer, §2.2.3):
DWORD dwMessageType | DWORD dwLength | DWORD dwReserved1 | DWORD dwReserved2 | BYTE[] byData. Min 8 bytes, max 8000 bytes. - DCN command message (OIP_Dcn, §2.2.3.3): wraps the RPC payload with
OIP_DCN_MSGTYPEheaderBYTE byDcnMsgType | WORD wFnId | BYTE byMessageTypeHeader=0x43.byDcnMsgTypeis one of MDSC_REMOTEPROCEDURE_REQ=3, MDSC_REMOTEPROCEDURE_RSP=4, MDSC_NOTIFY=5, MDSC_NAK=2. - The exact value of
MESSAGETYPE_OIP_Dcnis not stated in the source excerpt (onlyMESSAGETYPE_OIP_KeepAlive=0x00447027andMESSAGETYPE_OIP_ResponseProtocolError=0x00447020are given in Appendix B). - The remote controller must wait for the response before issuing another request; typical response time is < 0.5 s, max 10 s (§2.3.2).
- Heartbeat: send
MESSAGETYPE_OIP_KeepAliveevery 5 s when idle. The CCU closes the connection if no message arrives within 15 s (§2.3.1.1.2). Recommended to also heartbeat from the CCU side. - Each application (SC, SI, DB, MM, CC, IN, VT, AT, LD, MD, IC) requires the controller to call its
*_C_START_*/*_C_START_IN_APP/*_C_START_IC_APPetc. remote function to begin receiving notifications; call the matching*_C_STOP_*to stop. Ause countis incremented per registration — multiple controllers may register simultaneously. - System modes: Init, Config, Congress, Maintenance, Download, Down. Per-function availability is documented in §3.1.2 of the source.
- Booth numbering for interpreter desks: 1..31, desks per booth 1..6. A/B channels: 1..DBSC_MAX_INTERPRT_CHANNEL (31).
- Open Interface must be licensed (order code LBB4187/00) and enabled via the
Download and Licensing Toolshipped on the DCN DVD. Without this license the interface is not active even though port 9451 may be reachable. - All numeric constants used in the source are little-endian on the wire; MKWORD(LSB,MSB) macro produces a 16-bit WORD = (MSB<<8)|LSB, e.g.
SC_C_CHECK_LINK = MKWORD(18, 16) = 0x1012. - Capacity limits (Appendix B): DBSC_MAX_ACT_UNIT=576, DBSC_MAX_SPEAKERLIST=4, DBSC_MAX_NOTEBOOKLIST=15, DBSC_MAX_DELRTS=100, DBSC_MAX_DELCR=5, DBSC_MAX_DELCS=1, DBSC_MAX_INTERPRT_CHANNEL=31, DBSC_MAX_INTBOOTH=31, DBSC_MAX_DESK_PER_BOOTH=6, DBSC_MAX_LANGNAME=53, DBSC_MAX_CAMERA=256, DBSC_MAX_PREPOSITION=99.
- UNRESOLVED: Application manual cross-references for parameter struct semantics (e.g. exact
SC_C_SET_ENCRYPTION_ENABLEDparameter list, fullVT_C_*parameter sets, fullAT_C_*parameter sets, fullLD_C_*parameter sets, fullIC_C_*parameter sets) — this generic Open Interface spec only provides the function IDs and high-level descriptions; the per-application manuals (referenced but not present in this refined excerpt) carry the full C struct definitions. - UNRESOLVED: Voting chapter (§8) not present in this refined excerpt; VT function IDs are listed in Appendix B but per-function parameter structures are not in the source. The DCNC_APP_VT value (1) is given but per-action
paramsblocks are not populated. - UNRESOLVED: Cable pinout / RS-232 handshaking — the RS-232 signal definitions table in §1.3 is a generic reference table; the Open Interface itself is TCP/IP only.
- UNRESOLVED: Hardware specifications (voltage, current, power consumption, dimensions, weight) — not in this protocol spec; product datasheet would carry these.
- UNRESOLVED: Firmware version compatibility ranges — the OMF (executable downloaded into CCU ROM) version is reported via
szSWRelNumandbyMajorVersionOfDownloadedSw/MinorVersionOfDownloadedSw, but no compatibility matrix is stated in the source.

summary: "All 138 spec action wFnId hex values confirmed via MKWORD calculations in Appendix B; transport port 9451 confirmed; 4 callable source functions absent from spec but coverage ratio 138/142 = 0.97 exceeds 0.9 floor. (11 unresolved item(s) noted in Known Gaps.)"
Known Gaps
- SC_C_GET_CCU_CONFIG
- MM_C_RTS_INSERT
- IN_C_ASSIGN_UNIT
- IN_C_UNASSIGN_UNIT
- "voting chapter (§8) not present in refined excerpt; only Appendix B function IDs available. DCNC_APP_VT, SC, SI, etc. application-name mapping provided. Source is the \"Open Interface\" generic spec — individual application manuals describe per-function parameter structures."
- "MESSAGETYPE_OIP_Dcn constant value not stated in source (only KeepAlive=0x00447027 and ResponseProtocolError=0x00447020 given)."
- "MESSAGETYPE_OIP_Dcn value not stated; other OIP types in 0x00447xxx range"
- "detailed parameters not in source excerpt"
- "detailed voting flow not in source excerpt"
- "no safety-critical confirmation steps in source"
- "Application manual cross-references for parameter struct semantics (e.g. exact `SC_C_SET_ENCRYPTION_ENABLED` parameter list, full `VT_C_*` parameter sets, full `AT_C_*` parameter sets, full `LD_C_*` parameter sets, full `IC_C_*` parameter sets) — this generic Open Interface spec only provides the function IDs and high-level descriptions; the per-application manuals (referenced but not present in this refined excerpt) carry the full C struct definitions."
- "Voting chapter (§8) not present in this refined excerpt; VT function IDs are listed in Appendix B but per-function parameter structures are not in the source. The DCNC_APP_VT value (1) is given but per-action `params` blocks are not populated."
- "Cable pinout / RS-232 handshaking — the RS-232 signal definitions table in §1.3 is a generic reference table; the Open Interface itself is TCP/IP only."
- "Hardware specifications (voltage, current, power consumption, dimensions, weight) — not in this protocol spec; product datasheet would carry these."
- "Firmware version compatibility ranges — the OMF (executable downloaded into CCU ROM) version is reported via `szSWRelNum` and `byMajorVersionOfDownloadedSw/MinorVersionOfDownloadedSw`, but no compatibility matrix is stated in the source."
