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.

⚠ disputed: environment: 'Transmitter: -30 °C to 80 °C (-22 °F to 176 °F); Sensor: -40 °C to 150 °C (-40 °F to 302 °F)' — disputed by ACI Room Series BACnet/Modbus User's Guide, which specifies the operating temperature range as 1.5 °C to 50 °C (35 °F to 122 °F) [10.2.1]. The stated range belongs to the Duct/Averaging Series.
⚠ disputed: certifications: 'Plenum Rated' — disputed by ACI Room Series BACnet/Modbus User's Guide, as the Room Series is not plenum rated (only the Duct Series '-PB' enclosure is).
⚠ disputed: connector: 'Depluggable terminal block' — disputed by ACI Room Series BACnet/Modbus User's Guide, which specifies standard 'Screw Terminal Blocks' rather than a depluggable block (which is featured on the Duct Series).
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.
