E-Prime & BIOPAC

[Jivago]

Hi to all,

Iam doing an experiment with a Biopac recording signal.
In the e-prime experiment the participants have to see some images and
then assess them with a scale, and i want to record the electrodermal
and heart rate response.
I'am using some InLine objects: one in the beginig of the SessionProc
and other before any image presentation.
The pc that's receiving the signal sometimes record the signal for
some images but not for others.
I think that the problem might be due to the images time
presentations, for example some are presented 6000 ms and there is no
problem, but the others with 20 ms and so, sometimes record and other
times don't.

I'am sending the InLine that i'am using. If someone have a clue please
say.

1º InLine

'Sincroniza los relojes
'Clock.Scale = 1.00000027777785

'Resetea la salida del puerto serie
'serial.WriteInteger 1

'Resetea la entrada del puerto serie
serial.FlushInputBuffer

2º InLine

'Escribe el código
serial.WriteInteger 1

'Espera un segundo antes de enviar 0
sleep (1)

'Envía 0
serial.WriteInteger 0

Thanks in advance
