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.
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.

⚠ Remove mains and control voltage from the soft starter before attaching or removing accessories. Failure to do so may damage the equipment. — Starkest reads only; we never write a control register.
| terminals | B3, B2, B1 (RS485 serial port) |
| termination | 120 Ohm resistor matching cable impedance at both ends of the RS485 cable |
| connector | 6-way pin assembly for soft starter, 5-way male and unpluggable female connector for network |
| shield/ground | Connected to the GND device terminal at both ends and one point of the site protective earth |
| wiring notes | Twisted pair data cable with earth shield is recommended. |

| protocol notes | A multiple read across register boundary 40008/40009 will result in a Modbus Error code 05 at the Master. |
| model register | 40007 |
| firmware register | 40008 |
| identification notes | Register 40007 contains Product Type (4=CSX/CSXi, 5=MVS/MVX, 6=EMX3) and version. Register 40008 contains Serial Protocol Version. |

⚠ disputed: l1_current @ 599, l2_current @ 600, l3_current @ 601 — disputed by AuCom Modbus Interface Instructions (710-02653-00H) which maps L1 current to 40600 (0-based 599), but maps L2 current to 40601 (0-based 600) and L3 current to 40602 (0-based 601). The provided summary incorrectly shifted the register offsets for L2 and L3 current.
⚠ disputed: l1_voltage @ 602, l2_voltage @ 603, l3_voltage @ 604 — disputed by AuCom Modbus Interface Instructions (710-02653-00H) which maps L1 voltage to 40603 (0-based 602), L2 voltage to 40604 (0-based 603), and L3 voltage to 40605 (0-based 604).
⚠ disputed: powerscale_and_power @ 605, power_factor @ 606, motor_2_temperature @ 607 — disputed by AuCom Modbus Interface Instructions (710-02653-00H) which maps Powerscale and Power to 40606 (0-based 605), Power Factor to 40607 (0-based 606), and Motor 2 Temperature to 40608 (0-based 607).
Each rung states what it proved and what it did not. Gray until proven; green is earned by hardware only.
