The FSP5000RPS is typically a redundant power system or industrial power supply module (possibly from FSP Group, a known PSU manufacturer). The "RPS" usually stands for Redundant Power System, and "5000" may indicate a series or wattage class. Programming software for such units would be used to configure:
✅ Contact FSP directly – Request “FSP5000RPS programming software manual” via their industrial support form (www.fsp-group.com). Mention your part number (e.g., FSP5000RPS-xxx).
✅ Check OEM sources – If this unit came inside a server (e.g., Supermicro, Dell, HP), the programming interface may be locked to the chassis management controller.
✅ Search technical forums – Try site:eevblog.com FSP5000RPS or Reddit r/AskElectronics for user-shared documentation.

| 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)
The software interface described in the manual is utilitarian. It is not designed for aesthetics but for precision. Users can expect:
