Question Need Help Regarding UART to communicate with the STONE lcd module

[mrshell]

I can't use UART to communicate with the STONE lcd module. (https://www.stoneitech.com/)I tried different serial port applications, such as SSCOM, RealTERM, and SerialPlot, but nothing changed.I don't know what's wrong.

The lcd is supporting: RS232, RS485 and TTL UART standards
