本标准中的规范定义了门禁、安全、考勤和其他相关行业中使用的读卡器和控制面板之间的常用接口。接口的标准化使读卡器和控制面板的设计对于制造商来说是统一的，并且使系统设计和集成对于架构师、设计师、说明符和用户来说是系统化的。本标准提供了电气元件的规范，这些电气元件定义了从读卡器到控制面板的数据传输、电源要求/限制，以及对读卡器上包含的设备的控制。 这些元件用于设计连接读卡器和控制面板的功能电路。本标准供制造商采用，以建立一个通用接口，提供读卡器和控制面板的兼容性和互操作性，并供顾问、规范制定者和用户采用，以实现系统技术设计标准、要求或指南的一致性。

The specifications in this standard define a commonly used interface between card readers and control panels used in the Access Control, Security, Time and Attendance, and other related industries. The standardization of the interface makes the design of readers and control panels uniform for manufacturers and makes system design and integration systematic for architects, designers, specifiers and users.This standard provides specifications for the electrical elements that define the transfer of data from the reader to the control panel, power requirements/limitations, and control of devices contained on the reader. These elements are used to design functional electrical circuits that connect the reader and the control panel.This standard is for adoption by manufacturers to establish a common interface which provides compatibility and interoperability of readers and control panels and by consultants, specifiers and users setting criteria to achieve uniformity in the technical design criteria, requirements or guidelines of systems.
