ConfigureHeadstageRhs2116

sink Operator

Configures an ONIX Rhs2116 Headstage on the specified port.

The Rhs2116 Headstage is a serialized headstage with 32 bi-directional channels that are independently configurable to record electrophysiological signals or deliver electrical stimuli. The Rhs2116 Headstage can be used with passive probes (e.g. silicon arrays, EEG/ECOG arrays, etc) using a 36-Channel Omnetics EIB. It provides the following features:

• Two, synchronized Rhs2116 ICs for a combined 32 bidirectional ephys channels sampled at 30.1932367 kHz per channel.
• Real-time control of stimulation sequences.
• Real-time control of filter settings.
• Active post-stimulus electrode discharge and filtering allowing ~1 ms artifact recovery.
• Max stimulator current: 2.55mA @ +/-7V compliance.
• Stimulus active and stimulus trigger pins.

StimulusTrigger

Device

StimulusTrigger is a ConfigureRhs2116Trigger device operator contained by the ConfigureHeadstageRhs2116 operator with the following properties:

Property	Type	Description
Armed Acquisition	bool	Gets or sets if trigger is armed. If true, this device will respect triggers from the selected TriggerSource. Otherwise, triggers will be ignored.
Enable Configuration	bool	Gets or sets the device enable state. If set to true, a Rhs2116TriggerData instance that is linked to this configuration will produce data. If set to false, it will not produce data. Note that this does not affect the ability of the device to trigger stimuli, but only affects if trigger event information is streamed back from the device. To disable the trigger see the Armed property.
ProbeGroup Configuration	Rhs2116ProbeGroup	Gets or sets the Rhs2116ProbeGroup channel configuration.
StimulusSequence Acquisition	Rhs2116StimulusSequencePair	Gets or sets the stimulus sequence.
TriggerSource Configuration	Rhs2116TriggerSource	Gets or sets the trigger source. If set to Local, respect local triggers (e.g. via GPIO or TRIGGER register) and broadcast via sync pin. If multiple chips are connected to the SYNC pin, then this device becomes a transmitter to trigger stimulation sequences on other RHS2116 Trigger devices with TRIGGERSOURCE = 0x1 (receiver). If set to External, only respect triggers received from sync pin. Local = 0 External = 1
