SMU 2612B - Firmware 4.x - LabTracer Issue

Hello Community,

we are using several Keithley 2612B with Firmware 3.x and Labtracer without any problems.
recently we got a new 2612B with Firmware 4.x and i can not start a sweep. 
it always stops with an error that the "named channel could not be found".
connecting an old 2612B to the same PC and it works perfectly.


is there anything known that the new firmware 4.x is not compatible anymore with Labtracer?

Hello,
I cannot think of any intended firmware differences in 4.x that would account for it.

Can you capture a NI IO Trace during the attempt to use Labtracer with firmware 4.x and upload.
