Poll: Are You Interested in Roadtesting a PoE-to-USB-C Power and Data Adapter?

I wanted to get your opinion about roadtesting a PoE-to-USB-C Power and Data Adapter

 

Made by Microchip, the PoE to USB-CRegistered Power and Data Adapter connects Internet of Things (IoT) devices with a USB-C connector to Power over Ethernet (PoE) networks, enabling you to leverage the advantages of PoE and USB-C technologies. It provides both power and data to USB-C hosts.

POE to USCB-C Power and Data Adapter

Here are some more facts about this product:

 

The PD-USB-DP60 adapter enables flexible installation of USB-C devices, removes the need for a close power outlet and resolves the issue of limited USB cable length. The PoE source can be up to 328 ft/100m from the location of the USB-C device. A single Ethernet cable is needed while delivering up to 60W of USB power at the output of the adapter.

 

The PD-USB-DP60 connects with small PCs/Next Unit of Computing (NUC), interactive information kiosks, smart monitors, tablets, laptops, cellphones, cameras and other USB-C powered devices consuming up to 60W. The adapter is compatible with USB2.0 and 3.1 and will automatically provide to the end device the exact amount of power it needs.

 

  • Up to 60W output power
  • Enables powering of small PCs/Next Unit of Computing (NUC), interactive information kiosks, smart monitors, tablets, laptops, cameras and other USB-C devices
  • Provides power and data to USB-C Hosts
  • Allows 328 ft/100m installation range
  • Supports PoE Switches and Injectors from 15.4W and up to 90W
  • Plug and play USB-C Power, no configuration is needed, simple to use

 

Here's the datasheet:

  • I was surprised to see it offer 60W of power at the end of an ethernet cable.

    I did not think that much power was available from a standard ethernet port.

     

    I am not sure that all ethernet ports could support such a power push.

     

    Using one of these to power a modest device would be an interesting device to test.

    Ah thanks, it's behaving like the docking station for a laptop then, except that the power comes from the POE part, not an AC adapter plugged to mains.

    I now see the use case with NUCs and information kiosks.

    Once the drivers are installed, it becomes a "common" ethernet adapter.

  • The description above and the datasheet both say this:

    Converts both power and data to a single USB-C output

     

    But I have a hard time understanding how the "data" part would work with a single RJ45 plug on the input side of things. Where is the data coming from?

    I mean, look at the schematic from the datasheet:

    There is nothing on there that is providing USB datagrams to the tablet. Well, sure, the adapter appears to be "USB PD" compatible and will provide those datagrams for power delivery, but if I wanted to "talk" to that tablet from afar, I don't see how this could be happening with some sort of software installed on a host in the RJ45 side of things.
