The TTL124 is an innovative solution designed to meet the diverse needs of multi-modal event triggering.

This device enables the transmission of a single trigger signal, originating from the hardware or software of your choice, into four distinct triggering modalities.

Equipped with a straightforward USB power port, the TTL124 empowers users to precisely synchronize multi-modal data in correlation with stimulus time points.

At the core of the device is a DB-25 parallel port input, which typically receives a unique binary signal from a preferred hardware or software environment, such as E-prime, Psychopy or caming from hardware via trigger box hub and stimtrak.

The device is proficient in encoding up to eight bits of unique trigger identifiers, providing users with visible access to these identifiers via eight LEDs positioned at the rear of the unit.

The TTL124 has user-friendly design allows for the effortless sending of TTL triggers (stimuli) from the user's chosen hardware or software, streamlining the process of marking stimuli and freeing the user to focus on more critical aspects of their experimental work.

Furthermore, the device encompasses four DB-25 parallel ports, ensuring that the original input is duplicated into four separate yet identically timed signals (see video).

These can be dispatched to various external devices, such as EEG, eye-tracking devices, fNIRS devices in hyperscanning mode (see video about LiveAmp)

Additionally, the outputs can serve as inputs to other TTL124, thereby expanding the number of outputs available without compromising the precision of the signals.

The signal put put maybe triggered by BNC, DSUB9, USB2.0, Wireless emitter and other modalities (see video)
