2. Hardware Setup

Configure your EEG hardware parameters, bind electrode sites, and establish a stable serial connection.

Hardware Parameters

Parameter	Default	Description
Baud rate	921600	Serial communication speed
Sample rate	250 Hz	Samples per channel per second
Gain	—	Amplifier gain setting
RLD	ON	Right leg drive for noise reduction
Lead-off detection	Off	Options: fDR/4, 7.8 Hz, 31.2 Hz

Click Confirm parameters. The badge turns green: Parameters locked.

Acquisition Site Binding

Maps electrode positions to data channels.

1. Select a Placement system
2. Click Add binding — creates a new channel row
3. Type the site name
4. Click Confirm binding

Note: Only ch0 is the effective EEG channel. The heatmap builds from rolling site records.

Serial Connection

Both hardware parameters and site bindings must be confirmed before connecting.

Click Open wired connection → select device from browser dialog. The app sends EEGRST → EEGCFG → waits for ACKs.

Click Disconnect EEG device to close. Click Revoke device access to remove site permission.

Data Stream

Click Start collection to begin sampling. Optional CSV output: toggle ON → choose file. First 30s excluded for device warmup.

Stream states: Idle → Starting → Collecting → Stalled (no packet for 2s).

Filter Controls

4th-order Butterworth IIR band-pass filter. Adjust high-pass/low-pass cutoffs. Changing cutoffs clears the FFT window.
