notify Pinnacle 700 USB of the exact time an event occurs in E-Prime?

[BeckyL]

Has anyone used Pinnacle 700 USB (aka Pinnacle Studio USB-700) to capture video during an experiment? If so, do you know if this device can receive an event signal from E-Prime 2?

Someone on site already has the Pinnacle 700 USB from another experiment (years ago, not using EP). We are trying to video tape eye movement after the presentation of a stimulus by EP and determine the direction and latency of eye movements from fixation to the stimulus (or a distractor). Unfortunately, Pinnacle Studio User's manual and support website are very weak. It does appear that Pinnacle has a type A/ type B USB cable that connects to the computer as well as general purpose video cables.

I have no experience with that particular device, but from your
message (and from Googling "Pinnacle Studio USB-700") I gather that
this device communicates solely through USB. In that case, you are
sunk, unless you are *very* good with externall DLLs. Or maybe you
will get lucky and someone else here will point you to a DLL file
with general-purpose USB communication routines, along with
instructions for how to use that with E-Basic (i.e., VBA).

And as I often remind folks here, you might also take this up with
PST Web Support at
http://support.pstnet.com/e%2Dprime/support/login.asp , where they
strive to respond to all requests in 24-48 hours. And if you do get
an answer from PST staff, please extend the courtesy of posting their
reply back here for the sake of others.

Thank you for your reply. I am certainly not very good with external DLLs. PST has been very helpful in the past but they said they don't offer support for this type of device. HOWEVER, the good news is that we found an old box (Video Timer VTG-33) which appears to solve the problem. It connects between the video and the computer and time stamps the video as it is saved. The Pinnacle device and software can then be used to view the video (with a time stamp) frame by frame. We are in the process of testing it now.
