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 confirmed at the hardware-verified rung and at no rung below it.
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.

| terminals | 2-wire RS485, via 3 screw terminals |
| A/B polarity | All 'A' and 'B' connections are daisy chained together. |
| termination | The cable should be terminated at each end with a 120 ohm (0.25 Watt min.) resistor. |
| connector | 3 screw terminals |
| shield/ground | The screens should also be connected to the 'Gnd' terminal. |
| wiring notes | Typically 22 gauge Belden 8761 or equivalent. |
| max registers/read | 80 |
| response timeout | 150 ms |
| broadcast | not supported |
| protocol notes | Each request for data must be restricted to 40 parameters or less (80 registers). Exceeding this limit will cause a Modbus exception code. |
| identification notes | Register Order parameter at holding register 40041 can be used to detect/set floating point byte order. |

Each rung states what it proved and what it did not. Gray until proven; green is earned by hardware only.
If your device isn't here, upload its register map. Generation is free, and the connector keeps the rung it earns under testing.
To prove a connector against your own device, order hardware verification. If it doesn't verify, you don't pay.
Platform builders can license the verified library: machine-readable maps, the firmware matrix, API access.
