指定用于安装在标称12伏电池供电的农业拖拉机上的电气连接器及其引脚布局，以便在拖拉机安装的传感器和需要这些传感器信号的设备之间提供接口。因此，在标准化数字数据总线系统可用的情况下，提供了一个短期解决方案，用于在一组有限的拖拉机安装传感器和农业拖拉机及附属机械上的其他系统之间进行数据通信。

Specifies an electrical connector and its pin layout for mounting on an agricultural tractor with a nominal 12-volt battery supply for the purpose of providing an interface between tractor-mounted sensors and equipment requiring signals from those sensors. Provides therefore a short-term solution to date communication between a restricted set of tractor-mounted sensors and other systems on agricultural tractors and attached machinery, in anticipation of the availability of a standardized digital data bus system.
