<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>I have a question concerning the parallel port use in
e-prime and how to use multiple devices through it. We have a response mouse
and the scanner triggers both connected to the parallel port, the mouse uses
the data pins 2-9 and the fmri trigger pulses (TTL) are read in through pin 10.
For instance I have a slide to which the participant has to give an answer
through the response mouse, but this response should not terminate the slide. This
should be timed by the fmri-triggers. The scanner sends 26 pulses in one TR (2.5
sec). So I added 2 port devices in the Input/Duration Tag of the slide, one for
the mouse and one for the TTL Signals. The mouse is on address 378 and the TTL
on 379. The Mouse device has 2 allowable values, and the Correct Response is
coded in a previous list. I set the mouse on “Duration: Infinite”
and “End Action: none”, and the TTL is set to “Duration:
Infinite” and “End Action: Terminate”, and under “Advanced”
I set the Maxcount to the amount of triggers that the Slide should be on screen.
However, as soon as I press a button on the mouse, the slide does not go away. Apparently,
it ignores the other port device (TTL) and keeps going for the set duration (infinite)
of the device used. If I don’t press any mouse button, the experiment
runs through without problems. Can anyone tell me how to get the mouse responses
without interfering with the Maxcount of the other TTL port device?<o:p></o:p></span></font></p>
