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.

| A/B polarity | RS485 network cable connections are polarity sensitive (+ to + and - to -) |
| termination | Jumper selectable 120 Ohm resistor |
| connector | RJ45 for TCP/IP, screw terminals for RS485 |
| shield/ground | Incoming and outgoing RS485 cable shield wires should be connected together, but must not be connected to the Btu meter. |
| protocol notes | Resetting totals requires writing a 1 to a register, which takes longer to accomplish than reading registers and can lead to timeout issues. |
| power | 24 VAC input |

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.
