Need a comunication solution for a B&B Electronics USB Multifuction DAC module.

[jengel]

I have a B&B USB DAC that I would like to use on a test stand. I want to be able to minipulate the data in Lab View, But having a promblem communicating with the device.

Hello Jengel,

Thank you for contacting National Instruments.

What do you mean when you say that you are having trouble
communicating with your device?

To communicate with your device in LabVIEW you will need to have a
driver from B&B. You will not be able to use NI-DAQ or DAQmx as these
are drivers for NI's DAQ boards.

Try contacting the manufacturer to see if they have a driver or DLLs
for LabVIEW to call.

Are you able to retrieve data at all? If so, how?

Please respond with more information and I will be glad to help
further.

I do have the .dll for the instrument, but I am not very familiar with
the .dll call funtion of labview. What I was trying was to veiw the
device with VISA, but I could not get that to work. Thank You for your
input.

Hello jengel,

VISA is used to communicate with an instrument. I am assuming that
the B&B is a data acquisition module.

To communicate with your device you will need to use a Call Library
Function Node. It can be found by:

1 - Right click on the block diagram
2 - Select All Functions
3 - Select Advanced
4 - Select Call Function Library Node

You will then need to double click on the function to configure it.
Link the VI to your .dll in the Library Name or Path field. Then
select a function from the Function Name pull down menu. Consult your
Manufacturer�s User Manual for information about your library and
functions.

I hope this helps,
