* Example mapping—not final register addresses; project Modbus table and DI/DO diagram after contract. Webhook / REST require project enablement.
Protocol mapping table
Core tender and integration documentation—how platform events land on RCU hardware;specific addresses per project BOM appendix.
| Platform event | Integration method | RCU / register | Direction | Notes |
|---|---|---|---|---|
| Check-in | Modbus RTU/TCP | 0x0100room-state word | W | Triggers Welcome · seecard power |
| Check-out | Modbus | 0x0100 | W | Access revoke · vacant cutoff |
| Room VC / OCC / OOO | Modbus / API | 0x0101 | R/W | Align with PMS enum |
| DND / MUR | Dry contact + Modbus | DI-03 /0x0200 | R | Seedoor sign solution |
| Engineering / housekeeping card | Modbus | 0x0102 | W | Timed access · lock linkage |
| Device / scene | Integration method | RCU / register | Direction | Notes |

Hardware layer · three node types
Edge gateway
Protocol conversion, multi-RCU aggregation, RS485 isolation; TCP/RTU dual mode; firewall policy by integrator.
RS485 module / DI
Modbus modules,DI acquisition, relay expansion; address table with BOM.
Delivery boundary · Point Pur Intelligent vs integrator
| Capability | Point Pur Intelligent delivers | Integrator / client |
|---|---|---|
| RCU / modules / panels | ✓ hardware + wiring diagrams | Installation |
| Modbus register table | ✓ project documentation | Map to PMS/BMS |
| Local scenes / card power logic | ✓ RCU configuration | Policy confirmation |
| PMS / GRMS software | — | ✓ third party or custom |
| Room-state dashboard / NOC | — | ✓ integrator platform |
| Remote ops console | Optional capability | ✓ seecloud protocol guide |
Guestroom capabilities · public schedules
Layered architecture
PMS/BMS → integrator middleware → RCU/gateway → modules/panels/sensors. Bidirectional commands and status; scenes execute locally on RCU.
- Same doc set asaccess PMS table
- REST API indeveloper docs
- Excludes IPTV/voice platform integration
Typical integration sequence
① single RCU scene acceptance → ② Modbus read/write → ③ PMS room mapping → ④ alarm Webhook → ⑤ offline regression.

Documentation et enablement
Modbus register table
After contract export Excel/PDF per model—coils and holding registers.
DI/DO terminal diagram
Same volume as per-room wiring—SOS/contact/card power terminals matched.
REST / Webhook
Project API key; heartbeat, room state, alarm push format on developer site.
Integration support
Integrator supplies PMS simulator or test environment; Point Pur Intelligent aligns registers.
