Hello,
i am using an Moku:Lab which is connected via a USB Hub to the computer. It runs correctly in the Moku software. If i rightclick on the shown Moku:Lab in Moku Software, i can copy the IP which gives me an IPv6 string. I can also see the serial number of my device.
I tried to connect to the device by:
from moku.instruments import LockInAmp
i = LockInAmp("fe80::7269:79ff:feb7...")
and get the error message:
---------------------------------------------------------------------------AttributeError

and when trying to connect via the serial number:
i = LockInAmp(serial = "00178..")
i get this error message:

Does anybody know how to set up the connection with python?
Since it works with moku software, i assume there should be a way.
