数据链路

Cat 数据链路

Cat 数据链路是机器 ECM 的输入和输出途径。 Cat 数据链路与机器 ECM 的接头触点 J1-33 和 J1-43 相连。 数据链路用来载送控制器与监视器之间的通信。 数据链路是不可见的部件。 数据链路由内部控制电路和线束配线组成。 数据链路是双向的。 控制器可以通过数据链路接收信息,控制器也可以通过数据链路发送信息。 控制器将有关燃油油位、发动机冷却液温度和其他许多信号的信息发送给监视器面板。

CAN 数据链路

CAN 数据链路用于在下列模块之间进行通信: 机器 ECM, 开关面板 和 监视器 。 为使控制区域网数据链路正常工作,必须在配线线束中安装两个 120 欧姆终端电阻器。

行动警报

当发生高度紧急的情况时,行动警报会发声提醒操作员。 例如,发动机机油压力降到设置值以下。

行驶警报器

行驶警报器发出声响是为了提醒相关区域机器正在运动。
