ACP Workbench and UART

Hey everybody,

I’m trying to make a connection with ACPWorkbench over UART with an usb to ttl adapter based on the CH340 chip.
I tried every possible connection except 5v (don’t want to fry the board). Nothing seems to work. When I short the tx and rx pins of the adapter (no connection to the Arylic board) ACPWorkbench reacts with a message to shut down.
My question is does it support this adapter or do I need another adapter with an specific chip?

eh, the ACP Tool only connect to board via USB, the UART will not work.
