DS-K3M200 闸机门禁控制板如何接二维码读卡器
How to Connect QR Code Reader to DS-K3M200 Access Control Board
介绍:基于 Q340 和 JL700 的二维码读卡器，本文以闸机型号 DS-K3B801SX、DS-
K3B601SX、DS-K3B501SX 和 DS-K3Y501SX 的权限版 DS-K3M200 作为接入对象介绍 232
接线和配置。本文接线方法也适用于其他门禁控制板 232 接口接线。
Introduction: Based on Q340 and JL700 QR code reader, this article uses the turnstile model
DS-K3B801SX, DS-K3B601SX, DS-K3B501SX and DS-K3Y501SX authorized version DS-
K3M200 as the object to introduce 232 wiring and configuration. The wiring method in this
article is also applicable to the 232 interface wiring of other access control boards.
一、接线

第一种情况：如果二维码读卡器对外输出接口是 RJ45，这时我们需要做一根网线，插入 RJ45
头，另一个头线序通过查看该接口的管脚定义确定。
The first case: If the external output interface of the QR code reader is RJ45, then we need to
make a network cable, insert the RJ45 interface, and determine the line sequence of the other
said by checking the pin definition of the interface. As shown below:
