Overview
Mightex’s PolyEcho intelligent control module is built for multi-threaded, event-driven experiments, such as those in freely-behaving neuroscience animal research, where experimental events occur unpredictably. The PolyEcho enables precise coordination of devices in response to random, user-defined trigger events, ensuring reliable stimulation, data collection, and timestamping for downstream analysis.
- Supports asynchronous, event-driven control where trigger events occur in non-sequential, random patterns
- Allows each trigger signal to initiate specific, user-programmed responses (e.g., activating cameras, light sources, or other devices)
- Coordinates multiple hardware and software trigger inputs for synchronized device control
- Synchronizes signal/stimulation output and data acquisition across all connected devices
- Uses a shared internal clock to generate consistent, high-resolution timestamps for all events and actions
- Ensures accurate timing information for post-acquisition analysis and correlation of neural activity with stimuli

This schematic illustrates a typical data acquisition system which may include a wide range of equipment. The system may receive multiple hardware/TTL and software triggers, in response to which, it will activate data acquisition as per the trigger-specific workflow defined by the researcher through Mightex’s PolyScan software. At the heart of the system is the PolyEcho Multi-Channel Intelligent Control Module, which can handle up to 12 hardware/TTL triggers, and up to 32 software triggers, while also synchronizing and controlling all hardware devices in the system. In addition, PolyEcho is also able to send out additional TTL and analog signals to control other equipment outside the Data Acquisition System. Last but not least, all incoming trigger events and all control signals sent to the devices are logged with precise and unified timestamps.
