大家好,
我正在做毕业设计,需要用RS232-USB转换器连接电脑和气压计的Transmitter.
USB转换器我已经按照NI的要求正确的安装了,在MAX里面也能找到!
但是通过VISA程序,我根本读取不到数据! 我怀疑是程序错误。
请有经验的同学能帮助我!
谢谢了!
Hi Lixing247,
You would need the Instrument Drivers (仪器驱动程序) for your device(s). Try searching it in Instrument Driver Network
After downloaded the Instrument Driver for your device, extract and install it to your PC
i.e. C:\Program Files\National Instruments\LabVIEW X.X\instr.lib\
Re-start LabVIEW, and you should be able to find the ID under the Instrument I/O functions palette.
