USB-8451 does not appear in the DAQ-assistant menu

[Ricewind]

Hello,

I am using an USB-8451 device with LabVIEW 8.6. I have installed the 1.1.4 drivers of such device and both windows and MAX detect it. I have also renamed the alias and the status of the device is "This device is working properly".

The problem comes when I try to add a DAQ-assistant block to my project. I select the kind of input I want to have (digital line, though I tried them all) and LabVIEW does not detect any device.

I tried to do a diagnostic with VISA Test Panel. There I guess something is wrong, as when I execute a viRead i get as Return Status 'BFFF0015h' in red letters... but I do not really know what does that mean. The LED on the device is green and blinking.

Thank you in advance.

Can you address it directly by using a channel constant?

VI chain : Create a task, config channel*, run task, read from port?

It's not supposed to show up in the DAQ Assistant (and NI-VISA is certainly wrong) or haven't you read the manual?

You will have to write your own Labview code using the drivers that come with the USB-8451.  There are no Express VI's built for that instrument.  It is not very complicated if you read the manual as Dennis has suggested.

Thank you all for your replies... I had the idea of having used this device through DAQ-assistant in the past, so I did not go through that part of the user guide. Dumb of me.

Any idea of why can be the VISA analysis wrong?
