We’re using the Lumina response pad for fMRI experiments with Presentation and E-Prime. Currently a desktop PC is connected via serial port to the Lumina controller (LSC 400B) and a parallel port is used for detecting the scanner trigger.
We want to set things up so that researchers can run their fMRI experiments using laptops which just have USB ports. We’d like to use the Lumina controller to detect both the scanner trigger and the button presses, and we’d like to somehow convert the output from the Lumina controller to a signal that Presentation and E-Prime can use.
The NBS website says that Presentation can use National Instruments NI-DAQmx Devices. We’re considering buying the National Instruments USB-6501 digital I/O device and connecting it to the Lumina’s Accessory Connecter. The idea is that TTL pulses corresponding to button presses and the scanner trigger will be sent from the Lumina to the NI device, and then sent to the computer via USB.
Does anyone know if this will work, or if there is a better solution?
