EEG Pulse Duration with Onsetsignal

[Nate]

This is indeed VERY helpful.  If I was to measure the duration of the
pulse (the trigger sent is actually '9') using a voltmeter, I would
then connect the negative wire to the incoming PCI-DIO cable ground
hole (which one is this?) and the positive lead would then connect
to...hmm the chart below does not show 9....

This shows the pin mapping for this, but there is an error on the page
and I also can't tell which chart is actually for eprime.

Onto the other method/explanation: in this example then, I do not have
a prerelease for this particular slide, so the pulse duration is
probably1500ms.  Other triggers/slides are of different durations and
are hopefully not relevant....

However, now comes the potential problem of analysis in Brain Vision
analyzer, though I am not sure this is the correct forum for this (but
then again, I have not found a BV forum anywhere).  Anyways, if anyone
is familiar with this, I would really appreciate some input, as I am
kind of lost:

I have been told that the triggers/markers (or only the one marker of
interest?) need to be moved based on the length of the pulse.    So
in  this example the 5 (or 9 in my instance) marker would need to be
moved with an offset of 1500 ms. Anyone know if this is true?
