Set addresses of identical DAQ devices

[SonosJ]

Hi,

Is there a way to set address of NI instrument? I have multiple NI USB 5132 and would like to adress them so that I can identify individual instrument. Either in HW or setting it in labview will be acceptible.

Thanks

Each should have a unique name that you can see in MAX.

Thanks for your help. I am develpoing test code that can be deployed in many test stations. These test stations will use the same test code. Setting instrument ID manually to certain number is only way to use the same software in different test stations. Any other ideas?

DAQmx devices may also have a user specified Alias that can be much more meaningful than "DevN" You can set that in MAX or programatically through the System API

As part of your deployment include the MAX configuration in the installer and all of your systems will have the correct configuration.

Thanks, I still don't understand how to physically identifying each of them. I know programing them to be unique is easy but if I have to duplicate test system, how the MAX knows which one is which?

You will have to go by the USB serial number.  Plug one in at a time and see which one comes up.

This is another reason I avoid USB in my test systems.  PCI/PXI is so much easier to manage.

This cant be done in mfg floor when test system is deployed. Unless there is a way to identify each instrument, I have to change my test system to make all the equipment unique.

If you are using some custom cabling, you could use some DIO with readback to figure out which device is connected up with which interface.  Switch your devices as necessary in the code then.

Thanks for your suggestion.

Which is exactly why this is such a good Idea

Don't hesitate to give it kudos
