NEUROSPEC AG has manufactured a low-cost trigger interface to be used especially for notebook computers that lack a Printer Port / Parallel Port / PCMCIA Express Port. 8 data bits are sent via the MMB Trigger Interface Box (acts as a virtual COM port) to the EEG system with a sub-milisecond delay. For more specifications or an installation manual contact us via the Contact Page

The MMB Trigger Interface Box comes as a package and includes the MMB Trigger Box (9.5cm x 9.5cm x 2.6cm) itself, a USB connection cable, hardware drivers and an installation manual. Customers confirm, that the MMB Trigger Box works well with: Neurobs Presentation, E-Prime, Inquisit, OpenSesame, PsychoPy and Linux.


Technical Specifications

The MMB Trigger Box USB interface provides an 8bit output port that is plug- and pin-compatible to a standard parallel port. The box contains Arduino and hence uses standard Arduino drivers, which makes it compatible with almost any operating system. The box appears as serial port and trigger codes are sent to this serial port using PTB's IOPort function. The trigger codes appear with a delay of max. 180µs at the device output port (measured with Windows 7). MMB Trigger Box can be programmed according to your needs, i.e. triggers can go to high or low; switch off after 8 miliseconds; or can be switched off manually or automatically.

It works like a charm with Inquisit and MATLAB, and with Swiss precision, as far as we can judge it.

We tried your MMB Trigger Box in a couple of recordings now, and it works like a charm! This little device really makes our lives a lot easier; thank you so much!

Westfälische-Wilhelms Universität, 2016

I am very happy with the way it works. It's very easy to setup on a Windows machine and I can use it just like I would an old-fashioned serial port, so that's great.

University in Oxford, 2016

It works a treat! So, to confirm, it works with OpenSesame and PsychoPy.

Thanks so much! No more parallel ports!

Nottingham Trent University, 2016

We are very pleased with the MMB Trigger Box by NEUROSPEC. We have used it for research in our lab at the University of Zurich and can confirm it's versatility.
