Should I Connect the 120Ω Resistor on UART-to-RS485 Converter for 2-Module Communication?
I would say you should not short it. Leave it open as it is in the schematics diagram. If it's a Uart line then it shouldn't have an issue. But I would say you should check the datasheet and confirm what the manufacturer said about this.
