Dear all, Thank you so much for your reply! I have not yet got LabVIEW 7.1 on hand, so I have just installed the evaluation version of LabVIEW 7.0, but it still cannot read the signal from PCI-6220 with LabVIEW. I do not know which example I should use. I think the evaluation version does not have as many examples as the liscensed one, right?? Ayumi

Dear all, Is it possible to make PCI-6534 to read the input which is around 200mV? I read the datasheet which is available on ni.com and it says that PCI-6534 is 5V TTL. Does it mean that there is no way for it to trigger a reading as long as the voltage is smaller than 5V? Thank you very much for your attention!! Ayumi

Thank you for your reply! I cannot find any examples for DAQmx. Do you mean the examples under "Help" --> "Find examples" in LabVIEW?? There is no NI-DAQmx... Ayumi

Thank you for your reply! I can see the icon PCI-6220 on the left hand side in the list under NI-DAQmx in MAX and I could run the test panel and there was signal, but when I ran LabVIEW and tried to use this hardware with those examples provided by LabVIEW, it told me that the device was not yet configured. I have no idea what I should do to configure PCI-6220. Moreover, I would like to know whether the resolution of PCI-6220 is high enough to detect 200mV voltage. Thank you very much!!

Thank you for your reply! ^^ But how can I reset it to "traditional DAQ" mode??(The device is under directory "NI-DAQmx" now, as seen in MAX) Thank you ^^

Dear all, I am trying to use "Measurement and Automation explorer" to configure a piece of device PCI-6220 with accessory SCB-68. I have tried running self-test and it was ok. When I tried creating a new traditional NI-DAQ virtual channel at "Data Neighborhood" and I chose "Analog Input" --> "Voltage", but there is no hardware available for me to choose at the last step. I would like to know whether I did anything wrong (e.g it shouldn't be "virtual channel", etc). Thank you very much for your attention!! :headbang: Ayumi

Dear all, I am trying to write a library for the use in LabVIEW, but after I have finished writing the code and when I clicked "compile", the message "extcode: No such file or directory" came out as shown in the attached .jpg file. I have actually got extcode. h in LabVIEW (I searched for it and at last I found that it was in Program Files) I would like to know whether I have to put extcode.h and this library source code in the same directory or whether I need to put extcode.h inside the library directory of Dev C++ (I use it to write the code). Since I installed Dev C++ in my D drive instead of C-drive (but LabVIEW was installed in C drive), will that cause any problem?? Thank you very much for your attention!! Ayumi

I am trying to create Call Library Source File but when I compiled the file, there is an error message saying that no extcode.h ("#include "extcode.h" has already been in the .c file when I created this .c file with LabVIEW). I would like to know how I can solve this problem, and at the same time I would like to know whether I can write the code in C++ instead of C, will there be any difference when the executable code is used in LabVIEW?? This may be a stupid question but I am a beginner in LabVIEW (especially in the Call Library Function). Thank you very much!! ^^

I am using LabVIEW6.1 and I am working on a program that registers time(up to 3d.p. of second) when there is a signal. My aim is to save these recorded time to a binary file but at this stage what I get is only text files. Is there any method that I can change the type of output files into a binary one?? Thank you very much!! ^^
