Firmware update process
Users can update the firmware of their boards to keep up with any future updates that Aris may release. This is done via the USB connection and NOT via the white header on the board, which is only used once during the initial firmware flash at the factory. If you restart the PMD after sending the firmware update command, you can see the PMD list an HID device. And then? Opening PIC32UBL to update the PMD’s firmware.
Enabling the USB HID firmware update function, VID= 0x4D8 / PID=0x3C is just as easy. You just click Connect and sometimes you have to restart the PMD for the function to work. And then comes the loading of the hex file of the new firmware. To do this, you click on Erase-Program-Verify to erase the old firmware and load the new firmware into the MCU. If all steps are ok, you can see the same screen as below.
After the above steps, the PMD should have been updated to the new firmware. The calibration value is saved during the process, so you don’t need to calibrate the PMD again.
Where to buy and prices
At this stage, Cybenetics is already able to take pre-orders by sending an email to [email protected] or via the Hardware Busters online store to take pre-orders. A Powenetics V2 kit currently costs 975 Euros excluding VAT and shipping costs. There is no VAT for orders outside the EU and the same applies to business customers within the EU (reverse charge with VAT ID). However, those living outside the EU should also be aware of the possible import fees at customs. If there is more demand, more kits will follow. However, the expected dates for further kits also depend on the availability of the components.
Summary and Conclusion
I bought the Powenetics V2 because it is a really handy addition to the measurement equipment I already have. With NVIDIA’s PCAT, together with FrameView, you can certainly measure a lot of things more easily and uncomplicatedly, but the NVIDIA system reaches real limits (motherboard, CPU) especially when it comes to the power consumption of all components, because only some sensor values are read out there, but not really measured. My own PMD including riser card can also handle Molex and SATA, but it doesn’t have a 12VHPWR connection and is also much slower with intervals of 10 ms.
The setup with two 4-channel oscillographs in the master/slave in the lab has a much higher resolution than the Powenetics PMD, but I don’t always need this flood of data, on the contrary. Thus, the Powenetics PMD v2 is not a replacement, but a very useful and time-saving addition that can integrate the motherboard better and, above all, with higher resolution, especially for CPU tests. From that point of view, the whole thing was a very useful investment, as I can and have to work with it in a meaningful way. Purely for fun, of course, it does not fit with the range of functions and the price, you must always be aware of that.
