Register map(s) for this device, with a note of how far each has been checked. Addresses are 0-based, as on the wire. Scale and byte order are confirmed only at the hardware-verified rung.
Round-trips through a real Modbus stack with no overlapping addresses and a word-order-sensitive codec — the map is internally coherent and wire-decodable. Does NOT prove byte-order or scaling match a real device: the emulator is seeded from the map's own types, so a uniformly wrong byte-order still round-trips. Only hardware-verified confirms byte-order/scale on the wire.

⚠ 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). |

Each rung states what it proved and what it did not. Gray until proven; green is earned by hardware only.
