Inquisit syntax to trigger BIOPAC on and off to record data

Apologies upfront if this sounds like a stupid question. Does anyone know the syntax for getting inquisit to trigger BIOPAC to start and stop recording data at specific times ? I have a rough idea of how to do it on EPRIME but have no idea about Inquisit syntax.

Any help and ideas are most appreciated

Inquisit can trigger external devices via TTL signals through use of <port> elements. You will find this covered in the "How to Present TTL Signals Through the Parallel Port" topic in the Inquisit documentation.

The Auditory Oddball Task available from the Task Library at millisecond.com may serve as detailed example implementation.

As for the specific signals your BIPOPAC device expects to initiate or stop acquisition, you would have to consult the device's documentation.
