PCI card needed to output TTL pulses through computer via parallel port (case 26047)

Hi,

I have recently purchased a psychophysiology equipment (BIOPAC) and need to connect my deskstop computer to the STP100C part of the biopac machine ([URL="https://www.biopac.com/product/isolated-digital-interfaces/"]https://www.biopac.com/product/isola...al-interfaces/[/URL]) in order to sync the stimuli presented through DirectRT and Medialab with the psychophysiological data. In order to do this I will need to connect a 21-pin ribbon cable ([URL]https://www.biopac.com/product/ribbon-cables/[/URL]) to my deskstop computer, which doesn't have a 21-pin output. I asked BIOPAC the adaptor I will need to connect the ribbon cable to the computer but they told me to check with "the manufacturer of the stimulus presentation software" that I am using. May I know what PCI card can I use to output TTL pulses through my desktop computer via a parallel port?

The version number of my Direct RT software is 2008.2.103.1115.

Thanks!
