MRI Trigger Output Device
The MRI trigger output device detects pulses from the MRI and inputs the number 5 to the PC.

The MRI trigger output device sends this signal (the number 5) to the PC through the output control device. Therefore, the setup should be referred to from the output control device section.
 

Manual Trigger Output

When the knob labeled “MANUAL TRIGGER SELECT” is set to “INTERNAL” (top position), pressing the red button labeled “MANUAL TRIGGER PULSE” will input the number 5 to the PC.

Pre-Experiment Check
Before starting the experiment, check if the number 5 is correctly input to the PC and verify that there are no connection issues by pressing the “MANUAL TRIGGER PULSE” button.

Selecting the output destination

Select by photo switcher.
Default is [1].

1:Visual stimulus PC equipped in the operation room
2:USB (brought-in PC)

*When USB is reconnected or after some time has elapsed due to subject cancellation, etc., the default will return to [1], so please re-set or confirm before the experiment.
