ConfigureHeadstage64

sink Operator

Configures an ONIX multifunction 64-channel headstage on the specified port.

Headstage-64 is a 1.5g serialized, multifunction headstage designed to function with passive probes such as tetrode microdrives, silicon arrays, EEG/ECOG arrays, etc. It provides the following features:

  • 64 electrophysiology channels and 3 auxiliary channels sampled at 30 kHz per channel.
  • A BNO055 9-axis IMU for real-time, 3D orientation tracking.
  • Three TS4231 light to digital converters for real-time, 3D position tracking with HTC Vive base stations.
  • A single electrical stimulator (current controlled, +/-15V compliance, automatic electrode discharge).
  • Two optical stimulators (800 mA peak current per channel).

ConfigureHeadstage64 Workflow

Inputs & Outputs

Configure all devices in the device group.

This will schedule configuration actions to be applied by a StartAcquisition instance prior to data acquisition.

A sequence of ContextTask instances that hold configuration actions.

The original sequence modified by adding additional configuration actions required to configure all the devices in the device group.

Properties

Headstage64

These are properties of the ConfigureHeadstage64 Device Group configuration operator:

Property Type Description
Port PortName

Gets or sets the port.

The port is the physical connection to the ONIX breakout board and must be specified prior to operation.

PortA = 1
PortB = 2
PortVoltage double?

Gets or sets the port voltage override.

If defined, it will override automated voltage discovery and apply the specified voltage to the headstage. If left blank, an automated headstage detection algorithm will attempt to communicate with the headstage and apply an appropriate voltage for stable operation. Because ONIX allows any coaxial tether to be used, some of which are thin enough to result in a significant voltage drop, its may be required to manually specify the port voltage.

Warning: this device requires 5.5V to 6.0V, measured at the headstage, for proper operation. Supplying higher voltages may result in damage.

Name string

Gets or sets a unique device group name.

A human-readable identifier that is used as a prefix for the DeviceName of each device in the the group.
