how do I configur a 4350 USB?

[gnwtci]

The 4350 shows up on Measurement & Auto Explorer. And appears to be functioning. Under properties I selected the accessory as 2190. This is the TC interface which is connected. In the test panel the Thermocouples are responding to stimulus. However, My VI gives the following message:

Error -10401 occurred at AI Parameter

Possible reason(s):

NI-DAQ LV: The specified device is not a National Instruments product, the driver does not support the device (for example, the driver was released before the device was supported), or the device has not been configured using the Measurement & Automation Explorer.

My application lays out like this: Initialize, set powerline freq, set read rate, set channel mode, set scan list, aquisition start/stop, read, aquisition start/stop, simple error handler.

Thanks

Hi,

I send you several threads where I hope you can resolve your issue.

Thread 1# http://forums.ni.com/ni/board/message?board.id=250&message.id=3996&requireLogin=False

Basically, I´d check if you have the last version of NI-4350 and MAX if not it´d be better to update them. Moreover, take care if you are doing an incorrect conexion or you are inputting a voltage out of the range of the board.

I hope this help you

I tried to install the calibration script related to the first of the 2 links. But I can't find where to install it. The doc says put it as follows "To install this update, download the compressed file and extract its contents into the Calibration Executive\Procedures\NI4350 NI4351\ directory that is found in the Calibration Executive directory." I can't find this directory.

I did install the update to NI-DAQ 7.4. Had 7.1 before. But, isn't there supposed to ba a NI-DAQ application besidex MAX? I can't find one.

I am definitely lost here.

Hello gnwtci,

I'm guessing that the reason that the directory is not on your computer is because you do not have Calibration Executive installed. Calibration Executive is a piece of software that NI sells that allows you to perforfm device level calibration.

In regards to NI-DAQ. NI-DAQ is not application software but driver software. MAX is a utility that installs with NI-DAQ that allows you to configure your DAQ hardware as well as other NI hardware. Anytime you update any of your NI drivers (such as NI DAQ), the driver will install MAX if it is not already installed on your computer or will upgrade it to a newer version if possible.

You can go to this webpage to get the newest versions for your drivers:

I hope this clears things up a bit.

So do I need to buy calibration executive to fix this problem? The hardware I have is new and was calibrated by NI in December.
