通信适配器 III 和 Cat® 电子技师(Cat ET)维修工具的连接
以下所列为使用通信适配器 III 和 Cat ET 所需的部件:
(1) 电缆
(2) 317-7484 通信适配器总成
(3) 457-6114 CA3 Ethernet FLASH 电缆
(4) 当前版本的 Cat ET 程序软件以及兼容 IBM 的个人计算机

注: 除 Cat ET 软件外,还需要 Caterpillar Plus+1 维修工具软件。

使用下列维修工具来帮助诊断和排除电气系统故障。

JERD2129  最新版本的 Cat® 电子技师(Cat ET)维修工具 
  Windows 系统的个人电脑 
8T-3224  针尖总成 
7X-1710  万用表 
8T-8726  电缆组件(3 针) (3 针抽头) 
6V-3000  接头修理套件 (Sure Seal) 
190-8900  接头修理套件 (Deutsch)

237-5130  数字万用表 
257-9140  数字万用表 
146-4080(1)  数字万用表总成 
(1) 该万用表可使用 RS232C 电缆连接至笔记本电脑或 Dataview 工具总成以进行故障诊断与排除。

有关维修 Sure Seal 接头的说明,请参考专门说明书, SMHS7531。 关于 Deutsch "DT" 型接头的维修说明,请参阅专门说明书, SEHS9615。

不需要 Cat® 电子技师 (Cat ET) 维修工具来确定和清除诊断代码。 但是,使用 Cat ET 确定诊断代码的过程更快更简单。 Cat ET 还可以显示诊断代码的历史记录信息以及诊断代码的参数状态。 这些特性使得 Cat ET 成为故障诊断和排除中的有益工具。

使用数字万用表进行导通性检查或电压测量。 有关数字万用表的使用方法,请参阅万用表附带提供的用户手册。 7X-1710 万用表表笔用于在未断开接头的情况下测量接头上的电压。 把表笔电缆沿导线推入接头的背面。 8T-8726 适配器电缆有一个三针脚外接头。 适配器电缆用于进行传感器电路的测量。

注: 除了线束测试之外,对于当今的 Cat 电气电路不推荐使用比如 8T-0500 导通性测试仪一样的导通性测试仪或比如 5P-7277 电压测试仪一样的电压测试仪。
