How to send triggers timing to EEG through parallel port?

[Hong91101]

I just started using E-Prime 2, and hope to do computer-based neuropsych test and collect ERP data. We installed parallel port, and add the port in the Eprime2 through the structure-experiment-device. Now I want to send the probe trigger timing to the parallel port. Could you please help?

Thanks,

Hong

You might use the Task Events feature to do this. You should find
some informaiton about that in the "New Features Guide" that came
with E-Prime, as well as in the E-Prime Knowledge Base at the PST
website. You might also search this Group for "task events", as well
as "trigger", "eeg", etc.

Best,

Thanks. I tried your suggestions, but seems the parallel port is still not talking with eprime. Please see the attached image. What should I do? (Our IT guy confirmed that the parallel port was installed properly. )

Thanks,

Thanks for helping...

Well, first of all make sure that you installed the Port I/O device
driver when you installed E-Prime. Beyond that, please contact PST Support.

Hi, David:

Yes, I got the tech support from Eprime, and updated the windows, seems that helps with the setup.

Thank you for telling me about the task event, it is very helpful.

Best regards,

Parallel.WriteString "1" ' for marker 1?? This worked for me connecting two programs. But I did not use a parallel. I used a serial, so for my experiment I wrote Serial.WriteString "1" for marker 1. Info can be accesed through this example: http://truebra.in/?p=244

Good luck!!!
