Connecting E-Prime to Biopac

[Evertox]

Hi,

I am currently trying to trigger a Biopac system from E-Prime using an
STP100 and MP30. This works fine using a PCI DIO-24 digital card from
SuperLab but not when connected to the parallel port with E-Prime.

Has anyone used this combination in the past, and if so could you
supply the cable pin-outs between the two.
Note, this is an STP100 and not an STP100C. I have been in contact
with BIOPAC and whilst they have supplied a standard cable and an E-
Prime .es test program, the triggers do not appear.

A pulse can be measured on D0 from the parallel port but seems to be
dragged down when connected to the STP100 opto-isolator.

I know this is a hardware issue but surely there must be E-Prime users
that have tried this combination previously. I would appreciate any
help concerning this issue.

Thanks

Hi Anthony

Perhaps you could still use the DIO card? It would have
documentation, and you could just write to its port address

Can you use a Measurement Computing DIO 24 card with E-Prime?

Evertox,

Don't know about the MCC DIO 24, but we just got a STMEPM system from
BIOPAC, and E-Prime controls that through a MCC USB-1208HS-4AO. And
that works through calls to the MCC Universal Library, which must be
installed. Basically, this is a library of I/O functions provided
through a .dll file. You have to use Declare Function in the User
Script area to gain access to the library functions from E-Prime
script, and then it's just a matter of calling functions in inline
script as needed. For the STMEPM, BIOPAC provides a sample EP2
program, as well as .txt files for each of the script elements for
easy copy & pasting.

Based on that, I would guess that in principle you could use the MCC
Universal Library to control the MCC DIO 24 card. Of course, in
practice that might still present a challenge. Then again, if it
only takes writing to a port address as Peter suggests then it all
gets very easy, e.g., you might just use WritePort in inline script.
