PCI6221

我刚开始使用数据采集卡,按照书中介绍的将6221插入到插槽中,用一个Cable将它同附件CB-68LP相连,安装完驱动后在measurement&automation中进行了一些设置,然后用DAQassistant进行调试,在CB-68LP中的68引脚输入正电平5v,67引脚接地,可是DAQassistant中设置通道为Ai0结果显示位10.68v,当改变输入为3v时,输出仍然为10.68v,不知道是什么原因?请大家帮忙解决一下,谢谢!

Asks everybody to help to solve, thanks!

I just purchased a DAQ card PCI-6221 and inserted it into the PCI slot. I've then connected the cable (CB-68LP) and tried to perform some measurement and automation. While debugging using DAQassistant i've connected a 5v reference voltage to pin 68 and earthed pin 67, however DAQassistant seems to tell me the Ai0 (which is the relevant channel) is 10.68v. When I then change the input voltage on pin 68 it still returns 10.68v. Does anyone know the reason for this? Please help me solve this. Thanks!

Hello zhangleal,

 

I think you have come to the wrong part of this forum, however I will try to help anyway. First off, try downloading this

http://digital.ni.com/softlib.nsf/websearch/FEA4D55E1B3DA33A86257076006AA260?opendocument&node=13206...

Its the "DAQ Diagnostic Utility Version 1.0 for Windows 2000/NT/XP". This should determine if your card is calibrated and connected ok. Other than this, at a guess (as I'm still very new to this myself) it's either not returning any results at all or your selected scale is not set correctly. You should have the -10/+10v scale selected.

Sorry I couldn't be of more help.

Regards

John

你好zhangleal,
 
我认为您走向这个论坛的错误部份, 但是我将设法帮助无论如何。 首先, 尝试下载这
http://digital.ni.com/softlib.nsf/websearch/FEA4D55E1B3DA33A86257076006AA260?opendocument&node=13206...
它"DAQ Diagnostic Utility Version 1.0 for Windows 2000/NT/XP"。 这应该确定如果您的卡片被校准和被连接得好。 除这之外, 在猜测(因为我仍然是非常新的对这我自己) 它或者不退回任何结果根本或您选择的标度正确地不被设置。 您应该有-10/+10v 标度选择了。
抱歉我不能是更多帮助。
问候
约翰
