one seproj file multiple daqs

[harris33]

We have many USB-6251 based DAQmx devices, each connected to a different PC. I connect one of them, get SignalExpress 2.5 to read, say, ai7, and save it as a seproj file on our server

Then I start SignalExpress from another computer with a different DAQ (but same model) attached and load the seproj file.

This doesn't work. I think SignalExpress is reading the serial number of the boards, and doesn't recognise the new one. Although it is fairly trivial to re-configure SignalExpress to use the second board ar run time, it seems like an un-necessary step. Especially since we are using this with first year undergraduates, who are largely still stumbling around in the dark about all this data acquisition business.

Am I missing something obvious? (likely!)

Hello David,

I was able to make a simple SignalExpress project to read an analog input off of my PCI-6251 and then transfer it to another computer with the same card and run it directly.  One important thing to check is that the device names on both computers are identical in the Measurement and Automation Explorer (MAX).  To check this, open MAX and navigate to My System>> Devices and Interfaces>> NI-DAQmx Devices.  The name in quotes is what needs to match i.e. my PCI-6251 shows up as:  NI PCI-6251: "Dev1".  The name is quotes "Dev1" must match on every system to run it directly.

I hope this helps, and feel free to post back if you're still having trouble.

Have a great day!

Perfect!  On one PC MAX said the board was "Dev1" and on the other PC MAX said the board was "Dev2".

The lesson for us, and perhaps others, is whenever we change the actual board connect to a PC remember to us MAX to identify the new board as the same device number.

I can see arguments about why this behavior is the right thing to do, so we will be more careful about this in future.

Thanks for your help.
