NEUROSPEC AG has manufactured a low-cost trigger interface to be used especially for notebook computers that lack an LPT / Printer Port / Parallel Port / PCMCIA Express Port. 8 data bits (TTL) are sent via the MMB Trigger Interface Box (acts as a virtual COM port) to the LPT trigger input of any given biosignal amplifier (e.g. EEG system). The delay has been measured to be within the sub-millisecond range. 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 MATLAB.
MMB Trigger Box can be programmed according to your needs, i.e. triggers can go HIGH or LOW; switch LOW after 8 milliseconds; or can be switched LOW manually.
The following systems are only a list of tested biosignal amplifiers that work with the MMB Trigger Box. Every biosignal amplifier with a standard TTL trigger input (pins 2-9 as trigger inputs and pin 25 as ground) will work without any issues.
