所引用的dll文件
这是年初写的一个打开钱箱的工具,北洋的网上有现成的代码,现在只写了其它的,网络端口的需要重新配置,串口的是用发命令的方式打开的。
不是支持所有钱箱,请大家合理利用,需要对开启WMI服务,一般都开启的,不需要管。
一般超市使用时,都是讲钱箱与热敏打印机的RJ11口相连接,当打印时,会弹出钱箱,这种情况只要对打印机进行设置就可以实现钱箱的弹出。
当有需求,钱箱和打印不是同步操作时,就需要使用代码控制钱箱的弹出,这种情况下钱箱是直接连接在电脑上。
使用CASH DRAWER TRIGGER WITH USB INTERFACE连接到电脑的USB口就模拟了一个COM口,此时可以在设备管理器中看见
COM7就是USB转换后的串口号,记住它
弹出钱箱其实很简单,只需打个对应的串口,并向它写入数据就可以了,代码如下:
- string send = "" + (char)(27) + (char)(112) + (char)(0) + (char)(60) + (char)(255);
- System.IO.Ports.SerialPort com = new System.IO.Ports.SerialPort("COM7");
- com.Open();
- com.WriteLine(send);
- com.Close();
钱箱是不是弹出来了,就这么简单。
