MMBT-S Trigger Interface Box - Tobii Pro (Limited Edition)

Introducing the MMBT-S - Tobii Pro Limited Edition!

We've partnered up with Tobii Pro and have designed a Limited Edition MMBT-S Trigger Interface Box for Tobii Pro users! Sending triggers from Tobii Pro Lab is as easy as connecting the MMBT-S via USB to your computer running Tobii Pro Lab. Tobii Pro Lab users are required to update Tobii Pro Lab to version 1.194 (or later). Please check Tobii Pro Lab release notes for more information, available at https://www.tobiipro.com/product-listing/software/tobii-pro-lab/release-notes/

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 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. For more specifications or an installation manual contact us via the Contact Page. 

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 protective hardshell case, a USB connection cable and a USB memory stick with hardware drivers and an installation manual.

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.

Note for Tobii Pro Lab Users: When running the MMBT-S trigger interface box in Simple Mode and using Tobii Pro Lab for your experiment, Tobii Pro Lab sets the trigger pulse width to 33ms.

Features

• Sub-millisecond trigger marker transfer delay 
• Runs with Tobii Pro Lab software
• Windows 7/8/8.1/10/11, 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.

* for MP150/MP160 connect the MMBT-S through CBL110C to an STP100C/STP100D; for MP35/36 use STP35B.

Software Compatibility
