■ This is an article posted on June 2020, 11, so the content of the information may be out of date.

USB-serial (D-SUB 25pin type) conversion adapter on Unipos website MMBT-S Trigger Interface BoxPage has been updated.

Adapter to convert USB port to serial port of D sub 25pin female connector MMBT-S Trigger Interface BoxIs the successor to the MMB Trigger Box, and is a parallel port that triggers the presentation of stimuli in psychological experiments.*It is a device that can be sent using.
(* The connector shape is the D-SUB 25-pin shape used in general parallel communication, but the actual communication is serial communication.)

NBS Presentation, OpenSesame, PsychoPy,Inquisition We have confirmed the operation of software for psychology experiments such as Linux OS.AlsoE-primeCan be configured like a standard serial port.

 

MMBT-S Trigger Interface Box about

At the standard TTL (Transistor Transistor Logic) level, 8-bit data (TTL) is transferred to the LPT trigger input side of the biometric research system via the MMBT-S Trigger Interface BOX (virtual COM port). I will.

The connector shape is the D-SUB 25-pin shape used in general parallel communication.
* The actual communication is serial communication.

Major features

・ Trigger marker conversion delay is within milliseconds

・ Can be performed with major psychological experiments and stimulus presentation software
… NeuroBS Presentation, E-Prime, Inquisit, OpenSesame, PsychoPy, MATLAB, etc.

・ Cross-platform support
… Compatible with Windows 7/8 / 8.1 / 10, Mac OS X / macOS and Linux

· Can be run in two different runtime modes
… The runtime mode is a switch next to the USB socket, and you can select from a pulse mode that automatically switches the trigger signal High and Low periodically, and a simple mode that manually switches from High to Low (at any time).

・ 8-bit TTL output

-Ability to trigger on odd fields
… Built-in LED to visualize odd trigger marker codes (1, 3, 5, 7,…, 255, etc.)

 

Compatibility of biometric research systems

Compatible with biomedical instruments such as biosignal and amplifier systems with standard TTL trigger inputs (trigger inputs: 2-9 pins, GND: 20-25 pins).
