我如何...缩放重量显示 [英] How do I...Scale weight display

问题描述

您好我是从RS232端口发送的数字体重秤。

现在我想在我想要显示的应用程序中获取此信息。

来源没有人这样做吗？

C＃语言使用串口

Hi I am a Digital weight scale received from the RS232 port sends.
Now I want to get this information in my application I want to display.
The source does not anyone do this?
C # language using the Serial port

推荐答案

对不起，但我们可以;必须这样做 - 那里所有机器接口都没有标准，即使是通过RS232，如果不知道秤的确切品牌和型号，我们也无法帮助你。



您应该与创建它的人交谈 - 他们应该提供技术支持，并且会比我们更了解他们的产品。如果他们没有，那么找另一个供应商并要求退款！

Sorry, but we can;t necessarily do that - there is no one standard for all machine interfaces, even via RS232, and without knowing the exact make and model of the scale we can't help you very much, if at all.

You should talk to the people who created it - they should provide technical support and will know more about their product than we will. If they don't, then find another supplier and demand your money back!
