New hardware Pickering PXIe Chassis temperature and fan RPM

[peto0088]

Hi Martin,
I would like to monitor and log with HWiNFO64 Pro temperature and 4 fans on PXIe chassis.

PXIe chassis is model 42-925 manufactured by Pickering.
It is modular chassis where PXIe and PXI card could be plugged in and then through PCIe Gen 3 interface card are connected to the motherboard PCIe bus.
PC and PXIe chassis is linked by ADLINK PCIe-PXIe-8638 PCI Express Control of PXI Express bus extension cards.

In Pickering 42-925M datasheet is section about Chassis Monitoring Module which could through I²C interface (to SMB on backplane) could monitor temperatures, FAN tachos, and few more parameters.
I²C Address and Registers values are mentioned in datasheet.

Could I some how add these sensors to the HWiNFO. Or it must be done by you?

From HWiNFO Sensor summary, you could see that PCIe card and all PXIe slots are visible in summary.
I am attaching report and debug file. And Pickering 42-925M shorter and compressed version of datasheet. Original could be found here: https://www.pickeringtest.com/portal/web/256/content/private/manuals/42-925M.pdf

Pickering is manufacturing 8-Slot PXIe Chassis as well (only with 2 fans) model 42-924

Best regards
Peter

To add these sensors one would need to know the protocol used by the controller. This is certainly something proprietary the vendor won't disclose.
I can also see an Adlink SMBus controller present, so the I2C device is most likely connected to it. But this is also using a proprietary protocol.
Not possible to support without detailed vendor specifications including register sets for all devices.
