Hi there,
I own the EastTester ET5411 and have the same problem when trying to connect the ET4511 via USB/ com3 to a PC: "ET5410" do not match answer: "ET5411,V1.02.2034.029,09432030024,V1.11.2034.002" (there is no ET5411 in the search socket of the TestController SW).
On April 30iest, 2023 you posted, that you succeeded in editing the IDstring.
How did you do that?
Your help would be greatly appreciated
