The parPulse function cannot work in the NeuroScan Curry 9 system

Hi,

I used the trigger version of parPulse to send triggers to the NeuroScan Curry 9 system. However, no value was obtained in the event file. Is there something wrong with my code or EEG system?

parPulse(hex2dec('378'), 201, 1, 255, 2*10e-3,1)

Thanks

Actually, even no event file was produced.

Sample rate is 512 Hz.
