hi danill33

without any DAQ card how you can access the Daq Assistant..

you should be having daq card with Usb connection or with PCi card or PXI card

without you can not access the daq assistant. but if you wan to transfer your data then you can use UDP data transfer examples...

hope u understand

Hi Nabel,

              Using the Measurement&A utomation Can we simulate a DAQ device without DAQ card??

Yes, you can simulate certain devices through MAX. However, there are some decives which cannot be simulated through MAX.

hi danil

you can access Max without DAQ card but you can acquire data without any hardware connected

Max just show you the which hardware or card like PCI/PXI chasisss or card is conneced

hopes you undestand

No, you can acquire simulated data when you select to simulate a DAQ card in MAX.

Danil,

You need to provide the type of DAQ card you are using. Your VI shows a VISA Write and Read. These functions are not used for DAQ devices and you cannot simulate them and you cannot use the DAQ Assistant for non-DAQ devices.

yes ur right.. denis

Thanks to all for valuable suggestions.Yes I used VISA read and write functions.So in this case how to simulate to view a proper output??

Hi Fragger

               I have one more doubt.In my attached example there shows a dropdown list for VISA resourse name.Can it be a USB port??Using an usb CABLE can we read data

using that attached example??Or that example is capable of  serial port reading only??

plz reply

No. You cannot simulate a VISA device. You need something connected at the other end of a USB cable.
