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.

⚠ Before performing any work on the module, make sure that the pump and module electricity supply has been switched off and that it cannot be accidently switched on. — Starkest reads only; we never write a control register.
| terminals | Screw-less terminals |
| A/B polarity | A, B and COM (Common) |
| termination | Not present. External termination (100-150 ohm resistor) recommended on both ends. |
| connector | Screw-less terminals, RJ-45 for Ethernet |

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.
