Power Delivery - ACT AC7046 Manuel

7 |
ENGLISH
If your notebook supports DP alt mode (DisplayPort alternate mode) it also supports
MST. In this case the AC7046 will work as a USB-C to MST adapter. You will be able
to use the multiple video outputs. The connected screens will be recognized as
separate screens on your laptop / PC and can be used as an extended desktop.
Windows 10 has a short key to switch between the different display modes:
Use: "Windows key + P" an overview of display modes is displayed on your screen.
Please Note!!! MacOS does not support MST Daisy chaining. MacOS only supports
Daisy chaining with the Thunderbolt™3 standard. So the AC7046 will not provide the
desired result for macOS devices. In this case the connected screens only show a
clone (copy) of your main screen on the connected screens also called SST (Single
Stream Transport).

5.0 Power Delivery

The AC7046 supports Power Delivery (PD) on the USB-C port. This protocol enables
your notebook to be charged safely over one single USB-C cable. One footnote: all
devices within the power chain must support Power Delivery. Including the USB-C
cables. The devices and cables have built-in chips that communicate with each other
to decide the best PD profile to ensure a safe power delivery.
For example, if you connect a 45.0W USB-C charger to the AC7046 (supports PD
profiles up to 100.0W) and your notebook supports a USB-C PD profile of max.
65.0W. The max. power that will be provided to your notebook is 45.0W.
If for some reason in the example above, the USB-C cable is exchanged by a USB-C
cable which does not support PD (no built-in chip), your notebook will not be charged.
Besides this all, USB-C with PD enables charging in two directions. For example, you
can charge your smartphone with your tablet, but also your tablet with your
smartphone.
