NEUROSPEC AG has manufactured a low-cost trigger solution to be used especially for notebook computers that lack a Parallel Port or PCMCIA Express Port. Please note that our solution is powered by Arduino and has been programmed to send 8 bits via a COM port to the EEG system within sub-milisecond delay. For more specifications or an installation manual, go to our website or contact us directly. 

Package includes the MMB Trigger Box (7cm x 5cm x 2.5cm), a USB connection cable, hardware drivers and an installation manual useful for Neurobs Presentation. Customers confirm, that the MMB Trigger Box works well with: Neurobs Presentation, OpenSesame, PsychoPy and Linux. We have also received confirmation, that E-Prime can configure the MMB Trigger Box just as it would as a standard COM port (manual highlights installation).


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.




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!

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.

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

Thanks so much! No more parallel ports!
