e-prime/serial port to digitizing computer

[MarioLiotti]

I wonder if anybody has advise on how to get stimulus/response triggers generated by e-prime (sent out through a serial port) to the Biosemi EEG digitizing machine.

Is there a scheme available about how to build a connecting cable?

Thanks

The connection of triggers to the ActiveTwo receiver is described on http://www.biosemi.com/faq/trigger_signals.htm

The pin layout of a cable for an interface with E-prime is found on http://www.biosemi.com/faq/presentation.htm

We found we had to send a zero after sending an eprime trigger or subsequent triggers would sum. Hope this helps.
