Tripp Lite MODBUSCARD UPS management card

Register map(s) for this device, with a note of how far each has been checked. Addresses are 0-based, as on the wire. Scale and byte order are confirmed only at the hardware-verified rung.

coherence-checked

Round-trips through a real Modbus stack with no overlapping addresses and a word-order-sensitive codec — the map is internally coherent and wire-decodable. Does NOT prove byte-order or scaling match a real device: the emulator is seeded from the map's own types, so a uniformly wrong byte-order still round-trips. Only hardware-verified confirms byte-order/scale on the wire.

⚠ disputed: rating_input_voltage @ 1025 — disputed by Tripp Lite MODBUSCARD Owner's Manual (93-2987) which lists Rating Input Voltage at Modbus address 0x0401 (decimal 1026), while 0x0400 (decimal 1025) is 'UPS Type'

confirmed: comms defaults (baud rates 2400-19200, default 2400, RTU, parity N) — confirmed by Tripp Lite MODBUSCARD Owner's Manual (93-2987)
confirmed: physical connector and termination switches (SW3-7, SW3-8) — confirmed by Tripp Lite MODBUSCARD Owner's Manual (93-2987)
confirmed: identification registers (model_register 0x0503, firmware_register 0x050E) — confirmed by Tripp Lite MODBUSCARD Owner's Manual (93-2987)

The trust ladder

Each rung states what it proved and what it did not. Gray until proven; green is earned by hardware only.

generated — A prompt produced it. Unproven — anyone can regenerate this.
structure-verified — Decode path is structurally sound (addresses, widths, finite values). Does NOT prove word order or scaling.
coherence-checked — Round-trips through a real Modbus stack with no overlapping addresses and a word-order-sensitive codec — the map is internally coherent and wire-decodable. Does NOT prove byte-order or scaling match a real device: the emulator is seeded from the map's own types, so a uniformly wrong byte-order still round-trips. Only hardware-verified confirms byte-order/scale on the wire.
hardware-verified (software-key) x1 — Matched a real device with operator-attested readings as ground truth — the only rung that confirms word order + scaling on the wire.
