labview串口读取数据时报错,显示错误代码-1073807254,传输时发生奇偶校验错误,但实际上串口配置与仪器完全一致,且我用串口调试助手接收数据是没问题的,这是怎么回事,感觉visa read本身是否有问题?或者usb转RS485转接头应该是正常的,不然串口调试助手也不会接收到完整数据。我用labview实例中的串口读程序也是这种问题。
我用NI MAX调试串口读也有此报错。
我用虚拟串口工具调试labview串口读取,visa read却未报错。
实在是奇怪,第一次遇到。该怎么解决啊?

建议参考NI的知识文档:

对串口通信进行问题诊断。
另外建议更换串口通信的传输线缆,再次尝试。可能是噪声导致的校验错误
