Dry EEG Wireless TriggerHub
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 allows you to acquire triggers from and transmit triggers to many sources. consolidating up to 8 trigger sources into a single multi-channel output that inputs directly into DSI systems. 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 with DSI 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.
