Rs485 to usb interface. SIT3490E用作RS485通信 SIT3490是RS422芯片，可以实现全双工通信。 如果要用作RS485也是可以的，但是还是建议选用MAX485等芯片。 由于RS422可以接成RS485使用。 所以SIT3490E也可以结成RS485使用。 RS485具有两根线，需要把RS422的BZ短接用作RS485的B，AY短接用作RS485的A。 安装驱动：如果您的RS485转USB转换器是第一次连接到电脑，您可能需要安装驱动程序才能使用。 打开串口工具：打开您的串口调试工具，如PuTTY、Tera Term或其他串行通信软件。 配置串口参数：在串口通信工具中设置正确的通信参数，这包括：波特率（Baud Rate） Get professional RS485 to USB adapters with embedded protection circuits and fast communication capabilities for reliable data transmission.
