DSC（Data Service Center）用來接收和處理DTU發送過來的數據；如上圖，窗口1顯示當前登錄到DSC的DTU的信息，包括該DTU的電話號碼、IP地址和端口；窗口2顯示當前用短信呼叫DSC請求上線的DTU的電話號碼隊列，系統會自動處理該隊列，也可選擇手工處理，處理時，會向該DTU發送一條短信，包括當前DSC的Ip地址和端口；窗口3顯示接收到的數據和系統信息，可以選中窗口3上部的“16進制顯示接收數據”選項，以16進制顯示接收到的數據，“寫日志”選項為是否將接收到的數據寫到文本文件中，“應答”為接收到DTU數據后，是否向DTU發送一個應答數據包，轉發到串口，將接收到的數據從發送出去；窗口4為發送窗口，選中某個DTU后，該DTU的號碼會出現在發送窗口中，在右邊的文本框中輸入要發送的數據，即可將數據發送到DTU。
The purpose of this document is to define the format of the messages and data being
communicated between microprocessors used in heavy-duty vehicle applications. It is meant to serve as a
guide toward a standard practice to promote software compatibility among microcomputer based modules.
This document is to be used with SAE J1708. SAE J1708 defines the requirements for the hardware and
basic protocol that is needed to implement this document.
