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
