您将通过以下方式向其发送数据串口或通过USB库。如果它的USB接口是作为串行端口公开的，那么你仍然将它视为串行接口就是你的代码。如果制造商有一个SDK，请使用它。



Google用于c＃serial port，以获取有关如何通过串行接口发送数据的示例。

I'm using Pole display brand Posiflex:
- NORIRAKE mode

I have manual guide, but I don't understand at all to coding in C#, VB.NET.

Please give me sample code:
How can I send text to display and scrolling or running?

Thanks!

You're going to send data to it either over a serial port or through a library over USB. If its USB interface is exposed as a serial port, you still treat it like a serial interface is your code. If the manufacturer has a SDK for it use that instead.

Google for "c# serial port" for examples on how to send data over a serial interface.
