做通讯用的隔离磁隔,他可以产生5V to 5V DC Power 可以替代常用的两片高速光偶和隔离电源模块-do with the isolation of communications magnetic traps and He could have 5 V to 5V DC Power can be used to replace the two high-speed optical isolation and dual power supply module

RS485 可靠性 隔离 增加通信的可靠性，传输等等，很有用的哦

VB与串行通信编程实例：单片机采用了51单片机，多机通信中采用了利SM2来区分是数据还是地址，效果还可以。其中RS485部分采用了隔离转换电路，采用高速光耦6N137-VB and serial communication programming examples: single-chip microcontroller with a 51, multi-machine communication using Lee SM2 to distinguish the data or address,
