Hello

I recently purchased a used Hitachi F-4500 spectro fluorometer and installed the necessary GPIB drivers on my windows 11 PC and made all changes in order to communicate with the device.

But the application (FL solution) freezes when I start it.

I recorded the instruction flow (see attachment) and notice that the last instruction is IBWAIT(GPIB0,0x1000). What could cause this problem?

Any help is appreciated.

Best regards

Juergen
