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.

⚠ NEVER USE AC POWER. THIS WILL VOID WARRANTY AND BRING PERMANENT DAMAGE TO THE ELECTRONICS. CONNECT THE M12 CONNECTOR BEFORE POWERING UP THE INSTRUMENTS. — Starkest reads only; we never write a control register.
| terminals | M12 5-pin female connector |
| A/B polarity | Pin 4 RS485 B, Pin 5 RS485 A |
| termination | The VPInstruments junction box features a jumper that can be used to enable a 120 Ohm resistor. |
| connector | M12 5-pin female connector or M12 8-pin connector |
| shield/ground | Shielded twisted pair cabling must be used. Connect shield to safety ground on one point. |
| wiring notes | Connection of a third wire between the master and slave should be done to limit the common mode voltage. |

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.
