Description: 485H接口转换器是RS232至RS485转换器，可将发送数据TD和接收数据RD转换成差分半双工RS485信号，使RS232信号传输距离大大加长，是远距离点到多点通信的最佳选择。本转换器无需外接电源，自用串口转换电源；亦无需RTS信号控发，保证软件的广泛适应性-485H interface converter RS232 to RS485 converter is, can send data and receive data RD TD into a half-duplex RS485 differential signal to RS232 signal transmission distance significantly longer, is the best choice for long-range multipoint communication. The switch eliminates need for external power supply, power supply for personal use serial conversion also do not need to send RTS signal is controlled to ensure that a wide range of adaptive software

Description: 主要面对 以SPI SCI I2C RS232 RS485 为物理层的低速接口提供一个数据链路层。可以在MCU和PC之间传递数据，也可以在MCU之间传递数据，该数据链路层带CRC校验，带自动出错重传，带确认帧，带超时报警，总之是一个非常好用的数据链路层协议-The main face of SPI SCI I2C RS232 RS485 interfaces for the physical layer to provide a low-speed data link layer. You can pass data between the MCU and PC, you can pass data between the MCU, the data link layer with the CRC, with automatic error retransmission, with confirmation frame, with out warning, in short, is a very easy to use The data link layer protocol

Description: RS232，RS485是一个物理接口，简单的说是硬件。也可以说是一种通信接口。MODBUS是一种国际标准的通讯协议，用于不同厂商之间的设备交换数据（一般是工业用途）；所谓协议，也可以理解为有人说的“语言”吧，简单的说是软件(RS232, RS485 is a physical interface, in short, hardware. It can also be said to be a communication interface. MODBUS is an international standard communication protocol that is used to exchange data between different vendors (generally industrial uses); the so-called protocol can also be understood as a "language", simply said to be software.)
