零延时隔离技术的RS485总线节点设计

Design of RS485 Bus Node with Zero-latency Isolation Technology

在传统的RS485总线节点设计的基础上,选用ADI公司推出的新型带隔离的增强型RS485收发器ADuM2483,采用磁耦隔离技术进行RS485总线节点设计;并通过硬件实现零延时,使RS485总线的设计具有良好的抗干扰性、稳定性和易扩展性,大大提高了通信速率。

Based on traditional RS485 bus design, using a new enhanced RS485 transceiver ADuM2483 with isolation, RS485 bus node is designed through coupled magnetic isolation technology. Hardware zero-latency is realized, the design has good anti-jamming performance, stability and easy scalability, enhancing the communication rate.
