称重软件安装后，数据无法接收的原因？

作者:衡安称重软件公司来源:衡安称重软件发布于:2014年02月1日

称重软件安装后，数据无法接收的原因？
　　⑴仪表类型或波特率设置不正确，改为一致即可解决。
　　⑵仪表串口设置不正确。
　　⑶仪表的串行通讯方式应为：连续发送方式不接收。
　　如果在参数设定时，设为指令发送方式，则出现连接不通的现象。
　　⑷仪表与计算机的接线不正确或线头有短路现象。
　　⑸仪表串口损坏无法向处发送数据的检测方法：

　　万用表调至电压档，正负表针分别插在称重仪表的信号线与地线上，这时，万用表的指针会不停地左右摆动，说明仪表串口有输出信号，否则，即串口无输出信号串口损坏。如果是数字万用表，则会在６Ｖ到９Ｖ之间跳跃。用这种方法可测数据线的连接是否正确。
