The wireless trigger hub enables interfacing between Wearable Sensing’s Dry Sensor Interface (DSI) EEG headsets and other systems, facilitating device synchronization and third-party system integration. The hub acquires triggers from and transmits triggers to many sources. It consolidates up to 8 input sources into a single multi-channel output that connects directly into DSI or other systems. Triggers from the input parallel port are distributed across the connections on the output panel. The trigger output voltage is 0 – 5 V, which is sufficient to drive the trigger inputs of standard devices. The use of standardized input connectors and cables allows the user to connect and synchronize a wide range of third-party devices with the hub and DSI systems.
Used around the world by leaders in Research, Neurofeedback, Neuromarketing, Brain-Computer Interfaces, & Neuroergonomics.
