使用RS-232C模式在C＃中读取条形码。 [英] Bar code reading in C# using RS-232C Mode.

问题描述

我想在RS-232c模式下使用扫描仪读取条形码。我使用键盘楔模式完成了相同的操作，但是相同的解决方案并不合适，因为使用此模式需要始终激活表单。我购买的扫描仪是usb扫描仪，支持键盘和RS-232模式（型号为TVS-e BSC 101星）。我搜索usb以配合Windows 7的驱动程序，但无法找到任何合适的驱动程序。有谁知道哪个驱动程序将USB转换为虚拟COM端口或者我必须购买usb到rs-232转换器。

Hi,

I want to read bar code using scanner in RS-232c Mode. I have done same using keyboard wedge mode but the same solution is not appropriate as forms need to be active at all time using this mode. The scanner i have purchased is usb scanner which supports both keyboard and RS-232 mode(Model number is TVS-e BSC 101 star). I searched for usb to comport driver for windows 7 but could'nt found any appropriate driver. Do anyone have idea which driver is there which converts usb to virtual com port or I have to purchase usb to rs-232 converter.

推荐答案

与制造商联系 - 如果该设备通过USB端口支持RS232模式，那么很可能你只需要将它设置为模式，它应该在Windows中显示为一个comport。然后，您可以通过标准的.NET SerialPort类连接到它并读取它的数据。



如果不是并需要特定的驱动程序，那么几乎可以肯定只有从制造商处获得，所以无论如何都要从它们开始！

Talk to the manufacturer's - if the device supports RS232 mode via a USB port, then very probably all you have to do is set it to the mode and it should appear as a comport in Windows. You can then connect to it via a standard .NET SerialPort class and read it's data.

If it isn't and needs a specific driver, then you will almost certainly only get that from the manufacturers, so start with them anyway!
