<div dir="ltr"><div><div>PS. The screendump shows that you are using EP2 pro. This version allows you to specify triggers using Task Events on Trigger1 instead of the OnsetSignal-properties. In that case you SHOULD define a ParallelPort device first.<br>
<br></div>PS2: David also pinpoints an annoying issue with EP2: PreRelease is set to 'same as duration', which might result in zero-duration triggers...<br><br></div>Paul<br></div><div class="gmail_extra"><br><br>

<br></div>Also notice that value 128 corresponds to the highest bit of the 8 datalines. Also, adding the ParallelPort device is not required when using this trigger mechanism because you directly send data to the data register of the printer port. I'm not sure, but this might even give problems when the the LPT mode is not correctly set.<br>

The trigger cable is connected from the parallel port to the BrainAmp (in windows the resource tab of the LPT1 port says: Interval I/O 0378-037F, Interval I/O 0778-077F). In E-Prime I added the parallel port on LPT1 to the devices used. I need that in a series of numbers (with attribute "Target") that will be shown for 100ms in the slide "Target1", when will appear the number 1, a trigger should be send to my EEG recording... I created an Inline script (the one called Trigger) with this command: </div>
<div><br></div><div>----------------------</div><div>If c.GetAttrib("Target")=1 Then</div><div> Target1.OnsetSignalEnabled=True</div><div> Target1.OnsetSignalPort=&H378</div><div> Target1.OnsetSignalData=128</div>
<div> </div><div> Target1.OffsetSignalEnabled=True</div><div> Target1.OffsetSignalPort=&H378</div><div> Target1.OffsetSignalData=0</div><div><br></div><div>End if</div><div>---------------------</div><div><br>
</div>
<div>But it doesn't work, anyone can help me? I attached a screen of the sequence of my exp. </div><div>Thank you</div><span><font color="#888888"><div>PM</div></font></span></div><span><font color="#888888">
