connecting thermocouples to usb 6259

[ddrop]

I'm completely new to National Instruments software/hardware. I have a USB 6259 and I'm trying to directly connect multiple thermocouples to analog input. I'm unsure of which ports to which I should connect my leads on the pinout. Any help would be much appreciated.

ddrop,

Thank you for using the forums.  The best way to solve this issue would be to create a task in Measurement and Automation Explorer, and the connection diagrams are giving for your exact setup.

To do this:

1) Open up Measurement and Automation Explorer.

2) Right-Click on Data Management and Create New.

3) Click NI-DAQmx Task. Then Next.

4) Aquire Signals » Temperature » Thermocouple 

5) Choose which channels you want to connect to, use CTRL to select multiple channels. Click Next.

6) Name your task and click Finish.

7) On the task, choose which type of thermocouples to use.

😎 On the bottom of the task click Connection Diagram.  This will show you how to connect each channel, by click on the channel on the top of the window.

I hope this helps.

Regards,

Brian P.

Thanks, this was very helpful. However, the Connection Diagram tool does not support my device. Any advice?

Also, this might have something to do with the fact that I can only seem to create NI-DAQmx Tasks which correspond the analog inputs (i.e., AI 0, AI 0, ...) and not the pinout.

ddrop,

Here is a link for the USB-6259 Manual.  The pinouts are on pages 24,25 and 26.  Try updating your DAQmx driver to 9.3 from ni.com/drivers.  This will give you the newest version of Measurement and Automation Explorer which you have the Connection Diagram.  Those instructions that I sent you were step by step of what I went through with the USB-6259.  I hope that helps.
