USB Wireless Trigger

 USB trigger

The USB Trigger is a compact, portable system for sending time markers wirelessly to Cognionics EEG acquisition systems. It uses the same protocol as the larger Wireless Trigger and supports many of the same features including simultaneous broadcast to multiple receivers.

The USB Trigger uses a USB virtual serial port interface using the popular FTDI chipset with drivers for Windows, Mac OS X and Linux. It is compatible with most presentation/stimulus programs capable of outputting to a serial/COM port.

Because the USB Trigger uses a USB virtual serial port interface, the timing accuracy is limited to 6 ms. If you need increased precision a TTL interface and/or greater range, please refer to the larger Wireless Trigger
