MMBT-S Trigger Interface Box

The MMBT-S Trigger Interface Box is a virtual COM port (8-bit TTL output) to LPT/parallel port adapter. Package includes the MMBT-S, a USB cable and a USB memory stick with hardware drivers and installation manual. It features an in-built LED visualising odd trigger marker codes (i.e. 1, 3, 5, 7, ..., 255). The MMBT-S works well with NeuroBS Presentation, E-Prime, Inquisit, OpenSesame, PsychoPy and MATLAB.

The MMBT-S is 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 MMBT-S (virtual COM port) to the LPT trigger input of any given biosignal amplifier (e.g. EEG system). It features an in-built LED visualising odd trigger marker codes (i.e. 1, 3, 5, 7, ..., 255). The delay has been measured to be within the sub-millisecond range.

The MMBT-S trigger interface box comes as a package and includes the MMBT-S Trigger Interface Box (92.0 x 92.0 x 32.0 mm) itself, a USB connection cable and a USB memory stick with hardware drivers and installation manual. The MMBT-S trigger interface box works well with NeuroBS Presentation, E-Prime, Inquisit, OpenSesame, PsychoPy and MATLAB.

 

Technical Note 

MMBT-S trigger interface box can be run in two different modes: Pulse Mode and Simple Mode. In Pulse Mode, the MMBT-S trigger interface box automatically sets trigger markers LOW after 8ms HIGH period; whereas in Simple Mode the MMBT-S trigger interface box keeps the appropriate trigger marker HIGH, which needs to be pulled LOW manually. The runtime mode of the MMBT-S trigger interface box can be adjusted using the runtime switch next to the USB socket.

 

Features

  • Sub-millisecond trigger marker transfer delay 
  • Runs with major Psychological Experiment and Stimulus Presentation Software
  • Windows 7/8/8.1/10, Mac OS X / macOS and Linux compatible
  • Acts as a virtual COM port
  • Connects via USB to the stimulus/experiment computer and outputs 8 trigger bits via a D-SUB 25 (a.k.a. printer port)
  • Can be run in two different runtime modes: Pulse Mode or Simple Mode for high flexibility when transferring trigger markers
  • 8 data bits (TTL)

 

System Compatibility

The following systems are only a list of tested biosignal amplifiers that work with the MMBT-S trigger interface box. Every biosignal amplifier with a standard TTL trigger input (pins 2-9 as trigger inputs and pins 20-25 as ground) will work without any issues. Should you have any concerns, do not hesitate to contact us via the Contact Page. The MMBT-S trigger interface box has been successfully tested with the following biosignal amplifier systems:

  • ActiveTwo, Biosemi
  • ActiChamp / BrainAmp, Brainproducts
  • DSI-4 / DSI-7 / DSI-24 / DSI-VR300 / DSI-Hybrid, Wearable Sensing
  • fNIR Imaging System, BIOPAC Systems, Inc.
  • LABNIRS / LIGHTNIRS, Shimadzu
  • All MP-systems (incl. BSL, MP36, MP160 etc.), BIOPAC Systems, Inc.
  • neuvo, NeuroScan Compumedics
  • SynAmps RT, NeuroScan Compumedics

Other not listed biosignal amplifiers with a standard TTL (transistor-transistor logic) trigger input should work equally fine.
