<div dir="ltr">Thank you! Currently I am trying to use a virtual com port to interface both applications but have not succeeded yet since I do not have the EEG headset with me. So, that is a minor set back but today later I will be able to try this. None the less your advice an information is very useful. Thanks again I'll try also what you have said.</div>

<div dir="ltr"><div><div>You might run into all kinds of problems if you run an additional (acquisition) application on the same system. The main two issues I can think off are: 1) TIMING: eprime will boost itself with a high CPU priority, forcing other applications in the background. 2) the GUI: eprime will force itself in a non-cooperative directX mode, which doesn't allow you to switch to another application while the program runs.<br>
<br></div>So, traditionally, data acquisition systems run on their own computer. Interfacing can be done using parallel ports, serial ports or TCP/IP. Other hardware interfaces might be possible as well, provided that there is some API or SDK available to program it using E-Basic. If timing is critical, a parallel port would still be the best option I guess.<br>

I am trying to send stimulus presentation time; press and release time to be recognized in another application (TestBench) from the Emotiv Headset. Does anyone knows how does e-prime sends these data to another application? And maybe how to connect the 2 applications?
