Hello. Sorry for my English. I would like to know about the sensitivity K8061 to EMI. If I am applying to the digital input of K8061 signals at 5 … 10 kHz (TTL level), then after a while a CPU fail. Driver version 1.0.0.2, DLL v4.0.0.0, Demo program. If the input signals are low frequency, the K8061 works without errors.
