TIP

This is a Device configuration operator. Device Group configuration operators are recommended instead of Device configuration operators for interfacing with Open Ephys Onix hardware.

ConfigureUclaMiniscopeV4Camera

sink Operator

Configures the camera on a UCLA Miniscope V4.

Inputs & Outputs

Configures the camera on a UCLA Miniscope V4.

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

A sequence of ContextTask instances that holds all configuration actions.

The original sequence but with each ContextTask instance now containing configuration actions required to use the Miniscope's camera.

Properties

Property	Type	Description
Enable Configuration	bool	Gets or sets a value indicating whether the camera will produce image data. If set to true, UclaMiniscopeV4CameraData will produce image data. If set to false, UclaMiniscopeV4CameraData will not produce image data.
Focus Acquisition	double	Gets or sets the focal plane as a percentage up or down around its nominal depth. The imaging focal plane is controlled by using a Max14574 high-voltage liquid lens driver. This chip produces pulse-width modulated, 5 kHz alternative electric field that deforms a liquid lens in order to change the Miniscope's focal plane. The strength of this field determines the degree of deformation and therefore the focal depth. The default setting of 0% corresponds to approximately mid-range with an excitation voltage of ~47 VRMS. -100% and 100% correspond to the minimum and maximum excitation voltage of ~24.4 and ~69.7 VRMS, respectively.
FrameRate Configuration	UclaMiniscopeV4FramesPerSecond	Gets or sets the camera video rate in frames per second. Fps10 = 0 Fps15 = 1 Fps20 = 2 Fps25 = 3 Fps30 = 4 [Browsable(false)] Fps10Hz = 5 [Browsable(false)] Fps15Hz = 6 [Browsable(false)] Fps20Hz = 7 [Browsable(false)] Fps25Hz = 8 [Browsable(false)] Fps30Hz = 9
InterleaveLed Configuration	bool	Gets or sets a value indicating whether the excitation LED should turn on only when the camera shutter is open. If set to true, the excitation LED will turn on briefly before, and turn off briefly after, the camera begins photon collection on its photodiode array. If set to false, the excitation LED will remain on at all times.
LedBrightness Acquisition	double	Gets or sets the excitation LED brightness level (0-100%).
SensorGain Acquisition	UclaMiniscopeV4SensorGain	Gets or sets the camera sensor's analog gain. Low = 225 Medium = 228 High = 36
DeviceName Configuration	string	Gets or sets a unique device name. The device name provides a unique, human-readable identifier that is used to link software elements for configuration, control, and data streaming to hardware. For instance, it can be used to link configuration operators to data IO operators within a workflow. This value is usually not set manually, but is assigned in a MultiDeviceFactory to correspond to a fixed address with a piece of hardware such as a headstage. This address is used for software communication.
DeviceAddress Configuration	uint	Gets or sets the device address. This is a fully-qualified numerical hardware address of a device within the device table produced by an ONI-compliant acquisition system. This value is usually not set manually, but is assigned in a MultiDeviceFactory to correspond to a fixed address with a piece of hardware such as a headstage. This address is used for hardware communication.
DeviceType	Type	Gets or sets the device identity. This type provides a device identity to each device within the device table produced by an ONI-compliant acquisition system.
