I am using a cedrus response box 530 to collect responses and to trigger EEG equipment.  It is important that I only get a single ttl trigger for each button press but it seems that Inquisit is putting the response box into double pulse mode where I get a ttl trigger when the button is pushed and a second when the button is released.  Is there any way to control or alter this in Inquisit?

Could you please provide me a copy of the script you're using?  

I know that Inquisit doesn't contain any code that would set it to double pulse mode (a13).  However, if a response box is used as a stimulus via the <xid> element  we do set the lines to General Purpose (a10), the direction to output (a4), and optionally set the pulse duration (ap).  I haven't confirmed, but we may also set that if you just have an <xid> element in the script, but that would be an easily fixable bug.

If you just have a single XID device used just as an input device (and you don't need to scan for a specific one or alter the pulse duration) you can just specify /inputdevice = xid in <defaults> and omit the <xid> element and Inquisit shouldn't touch those settings.

Thanks and Enjoy,
Erik

FYI - I've just posted an updated version of Inquisit 4.0.6 that should fix this problem. You can download and install from our download page:
http://www.millisecond.com/download/
You'll have to uninstall your existing copy of 4.0.6 before you can install this one.
Give it a whirl and let us know if the problem persists.

Thanks,
Sean
