JT808教程：设置/查询终端参数

REDISANT 提供互联网与物联网开发测试套件 #

互联网与中间件：

工业与物联网：

在JT808协议的学习和调试过程中，一款终端模拟器非常重要，推荐 JT808 Terminal Simulator，官网下载地址：https://www.redisant.cn/jt808terminal

过程讲解 #

平台通过发送设置终端参数消息设置终端参数，终端回复终端通用应答消息。平台通过发送查询终端参数消息查询终端参数，终端回复查询终端参数应答消息。

此过程中使用的消息类别有：

  • 0x8103：设置终端参数
  • 0x8104：查询终端参数
  • 0x8106：查询指定终端参数
  • 0x0104：查询终端参数应答

使用模拟器 #

  1. 启动软件后，如果没有终端，则创建一个模拟终端，如何创建终端
  2. 点击启动终端按钮后，终端会立刻进行注册和鉴权
  3. 双击左侧终端参数，打开终端参数标签页

双击“值”列，可以随意修改参数值。

在软件的最上面一排按钮中，单击通信细节按钮，既可查看该过程中的所有消息。
