UCD3138FW-PSFB: Question about the GUI of UCD3138 PSHB

Part Number: UCD3138FW-PSFB

Hello, why open the output power calculation in the GUI interface, but the output is blank? When I look at the log information, read_iout_all reading is invalid. The PMBUS function in 0x8c returns the current value, but why can't I read the data?Looking forward to your reply, thank you!

It does seem to be an issue with the GUI. I see the same issue with the new versions of the GUI, but when I run the old versions, and when I just send the command to read iout, I get a valid response. Let me ask the GUI guy and get back to you. If you have an older version of the fusion digital power designer, say 2.0.xx, try that. Those seem to work fine.

Hello,

I have been able to reproduce the issue. It is related to the GUI calculating the power from the vout and iout, since the read pmbus command is not supported by the firmware. I will let you know when there is a new installer for you to try. We hope to resolve the issue within the next two weeks. If you implement the command for read pout it should work immediately.
