Hi Suresh,

You can get your DAQ device names by using the "System" DAQmx property node. It is found under the function pallette in NI Measurements >> DAQmx Data Acquisitions >> DAQmx Advanced >> DAQmx System Setup.

I have attatched an example that uses this.

Thanks the problem is i am using LAb veiw 7.0 RT and it does not support NI DAQ Qmax. I want a solution in traditional method.

Hi Suresh,

In Traditional DAQ you can find this information by using the "Get DAQ Device Information" VI. You can see in my attatched how the for loop tries to get the device serial number for each device number in your system. If no device is at a specified number the serial number will be 0x00000000.

Hai ,

it works fine but the problem i am facing is that when i put a PXI 6071 Card in Slot 2 and PXI -6070 in slot s 3,4,5,6 the program detects only pxi 6070 cards only .


I am using visa to detect the cards and slots . if posible if slot information card ,device information and device number set can be combined it would be great.

I am sending you the VI used to detect the Cards,

Please MAke sure that in the Max Visa properties
Show all PXI/PCI devices accesible by VISA option is enabled.

Please find the Vi as attachment
