I would like to use VividUnit as a standalone display with a browser in kiosk mode, powered via PoE.

Two issues:

1) I noticed that Vivid Unit doesn't always power up when connected to PoE (to a Cisco Cat9k series switch supporting 802.3af/at) and pressing the power button. No issues with USB-C.

2) Is there a way to have Vivid Unit start up automatically when power is supplied without using the power button?

Thanks in advance

Alex

We never met the first issue. It will be helpful to check what voltage is actually provided to Vivid Unit.

As for the 2), it is possible but you will need to solder a 0 Ohm resistor to the board. It is R297 in the schematic, which is not populated by default. However it will be quite difficult to do, because its footprint is on the other side of the PCB (under the screen), not to mention the footprint is also very small.
