Does anyone know the syntax for getting inquisit to trigger BIOPAC to start and stop recording data at specific times ? I have a rough idea of how to do it on EPRIME but have no idea about Inquisit syntax.<div><br/></div>Any help and ideas are most appreciated<br/>Thu, 06 Mar 2014 04:22:21 GMTbUENORE: Inquisit syntax to trigger BIOPAC on and off to record datahttps://forums.millisecond.com/Topic12567.aspxMany thanks!<br/>Thu, 06 Mar 2014 04:22:21 GMTbUENORE: Inquisit syntax to trigger BIOPAC on and off to record datahttps://forums.millisecond.com/Topic12566.aspxInquisit can trigger external devices via TTL signals through use of &lt;port&gt; elements. You will find this covered in the "How to Present TTL Signals Through the Parallel Port" topic in the Inquisit documentation.<div><br/></div>The Auditory Oddball Task available from the Task Library at millisecond.com may serve as detailed example implementation.<div><br/></div>As for the specific signals your BIPOPAC device expects to initiate or stop acquisition, you would have to consult the device's documentation.<br/>Thu, 06 Mar 2014 04:18:32 GMTDave
