Register map(s) for this device, each at the trust rung it earned. Addresses are 0-based as on the wire; word order and scaling are only confirmed at the hardware-verified rung.
Read + decoded cleanly over a real network vs an independent third-party Modbus test server (transport and framing; reads are remapped into the server's register window, so the map's own addresses are NOT exercised). Does NOT prove word order/scaling against the actual device.

⚠ Due to safety considerations, the only override values permitted in the case of actuators for fire dampers are Open (1) and Fast_closed (6). The operating position (Open) must also be repeated within 120 seconds (recommendation: 90 sec.). — Starkest reads only; we never write a control register.
| terminals | Plug-screw terminal, 3-pin (Modbus RTU and MP-Bus), 2-pin (Supply) |
| A/B polarity | D-, D+ ┴ |
| termination | 150 , adjustable via DIP switch |
| connector | Plug-screw terminal |
| isolation | The GND of the RS485 line is galvanically isolated from the MP-Bus GND. |
| wiring notes | All terminals suitable for 2 x 1.5 mm2. Tool connector is RJ12. |
| response timeout | 2 ms |
| sentinel values | 65535 is entered for absolute/relative volumetric flow if the actuator type does not support it. |
| protocol notes | The response delay of the device is set to a fixed 4 ms with 9600 Bd. A delay of 2 ms is used as a default with higher baud rates. Adjustable via register 1003 (2...100 ms). |
| serial register | MP[n] + 9, MP[n] + 10, MP[n] + 11 |
| firmware register | 1004 |
| identification notes | Service registers 1001-1004 (former 161-164) provide service information. |

Each rung states what it proved and what it did not. Gray until proven; green is earned by hardware only.
Have a device that isn't here? Upload its register map — generation is free, and the connector earns its rung by being proven, not claimed.
Need it proven on your own device? Hardware verification — if it doesn't verify, you don't pay.
Building a platform? License the verified library — machine-readable maps, firmware matrix, API access.
