Iskra MC3x0x power meter

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.

interop-verified

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.

link settings as documented (unverified): RTU; default 115200 8N2; unit ID 33; Modbus and DNP3 protocol are enabled via RS232 or RS485 or USB communication port. Factory settings of communication are #33\115200,n,8,2.

⚠ Service USB communication is not galvanic separated! When using service USB communication, power supply and measuring voltages need to be disconnected! — Starkest reads only; we never write a control register.

The trust ladder

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.
