mulitple scopes in linux

[Torfey]

I'm using two Analog Discovery 2's in an embedded Debian linux environment using the python interface with my own code.  I need to be able to know which physical scope I'm connecting to when I open both scopes because even though the usb assignment might change, the wiring won't. So I need to know in software which scope is which.

Can you suggest a way to choose which scope to connect to?  Or, failing being able to know ahead of time, what's the easiest way to know which scope I've connected to and possibly close it and switch to the other?

Thanks.

Hi @Torfey,

Here is the Waveforms SDK reference manual. Under 1.1 on page 4 it describes the Call enumeration functions to discover connected hardware devices. Which should allow to to choose which device you are connecting to.

Thanks.  I was able to use the FDwfEnum and  FDwfEnumSN calls to get the serial number of the devices and associate them with the idxDevice device index. Then, knowing from outside which serial number AD2 is wired where, can then look up that SN's index.
