使用 ADM3252E 总线收发器的隔离式 USB 至隔离式 RS-485/隔离式 RS-232 接口
使用 Analog Devices 的 ADM3252EABCZ 的参考设计
设计简介
电路在流行的 USB 总线和 RS-485 或 RS-232 总线之间提供完全隔离的连接。信号和电源隔离可确保 USB 设备接口与工业总线或调试端口的安全,从而实现 TIA/EIA-485/232 总线流量监控,并方便地向未配备 RS 的 PC 发送和接收命令-485或RS-232端口
说明
Circuit provides a completely isolated connection between the popular USB bus and an RS-485 or RS-232 bus. Both signal and power isolation ensures a safe USB device interface to an industrial bus or debug port, allowing TIA/EIA-485/232 bus traffic monitoring and the convenience of sending and receiving commands to and from a PC that is not equipped with an RS-485 or RS-232 port
