Digital Inputs

The NeuroLight Stimulator channels can be started and stopped through the digital input pins on the stimulator hardware.

Each channel has a corresponding digital input pin. A high (+3.3V) level on a pin will start the channel assigned to that pin, and a low (0V) level will stop the channel.
The channel will only start if it’s armed.

Digital Inputs

Digital Outputs

The NeuroLight Stimulator channels can be monitored through the digital output pins on the stimulator hardware.
By default, the DO pin for each channel goes high (+3.3V) when that channel is playing, and low (0V) when it is stopped. This behavior can be altered in the settings.
