Description: PullSDK接口支持TCP/IP和RS485通信协议，并支持UDP广播方式搜索门禁控制器及修改门禁控制器的IP地址、子网掩码、网关。
PullSDK接口使用C语言开发，对数据通讯做了高度优化，使其成为一个简洁高效的访问接口。
PullSDK接口在设计开始参考了SQL，但更考虑到业务中最常用的模型，是精心提炼出来的一组接口，做到了设计、实现、使用三方的平衡
-PullSDK interface supports TCP/IP and RS485 communication protocol, and supports UDP broadcast the search access controller and modify Access Controller IP address, subnet mask, gateway. PullSDK interface developed using the C language, and is highly optimized for data communications, making it a simple and efficient access interface. PullSDK interface design reference to SQL, but take into account the most commonly used business model is refined from a set of interfaces to do the design, implementation, use the tripartite balance Platform: |
