The RXD / TXD port of host-computer is respectively linked with the TXD / RXD ports of decryption equipments , and the communication protocol defined by user is used .
主机RXD/TXD端分别与从机TXD/RXD端连接，采用自定义协议通信。

As CAN communication controller communicates by semi duplex mode , it 's RXD pin connects with TXD pin that can make the design compactly , but the controller is not connected with transceiver , communication distance is short and the anti-jamming characteristic debases .
由于CAN通讯控制器采用半双工方式通讯，若将通讯控制器的接收端和发送端相连，可简化设计亦能够实现通讯，但是无法与收发器连接，从而缩短了通讯距离并降低了抗干扰性。
