These are not in the public datasheet – derived from reverse engineering the FSP firmware.
| MFR Code (0x9A subcommand) | Function | Allowed Values |
|-----------------------------|----------|----------------|
| 0x01 | Active current sharing mode | 0 = Master, 1 = Slave, 2 = Auto-negotiate |
| 0x02 | PSU health check interval (ms) | 10–1000 |
| 0x05 | EEPROM write protection | 0 = Disable, 1 = Lock all |
| 0x08 | Power-on delay after AC restore | 0–5000 ms |
To write MFR code:
# Example: set unit to Slave mode
dev.write_byte_data(0x9A, 0x01, 0x01)

Voltage calibration (two-point):
Current calibration (shunt or electronic load): Similar two-point method using external ammeter. These are not in the public datasheet –
❌ Incorrect calibration can cause instability. Record original values before changes.
The programming software for the FSP5000RPS is typically a desktop application (Windows-focused) with modular subsystems:
