The following tables list the members exposed by IGpibInterfaceSession.
Public Properties
| Name | Description | |
|---|---|---|
 | AddressState | Indicates whether the specified GPIB interface is currently addressed to talk or listen, or is not addressed. |
| AllowDma | Specifies whether direct memory access is enabled. In some cases you may not be able to change whether DMA is enabled, so reading this property value may not return the same value that was set. |
| AtnState | The current state of the GPIB ATN (ATtentioN) interface line. |
| DeviceStatusByte | The 488-style status byte of the local controller associated with this session. |
| EventQueueCapacity | The capacity of the event queue - the maximum number of pending events. (Inherited from Ivi.Visa.IVisaSession) |
| HardwareInterfaceName | Human readable text that describes the hardware interface. (Inherited from Ivi.Visa.IVisaSession) |
| HardwareInterfaceNumber | The board number of the hardware interface. (Inherited from Ivi.Visa.IVisaSession) |
| HardwareInterfaceType | Specifies the hardware interface type (GPIB, ASRL, etc.). (Inherited from Ivi.Visa.IVisaSession) |
| HS488CableLength | The total length of the GPIB cable used in the specified GPIB interface, in meters. If HS488 is not implemented, the value of this property is -1. |
| IOProtocol | The protocol type for I/O communication with the physical resource. In some cases you may not be able to change the protocol, so reading this property value may not return the same value that was set. |
| IsControllerInCharge | Indicates whether the specified GPIB interface is currently the controller in charge (CIC). |
| IsSystemController | Specifies whether the specified GPIB interface is currently the system controller. |
| NdacState | The current state of the GPIB NDAC (Not Data ACcepted) interface line. |
| PrimaryAddress | The primary address of the local GPIB controller used by the given session. |
| RawIO | A reference to the raw I/O interface. |
| RenState | The current state of the GPIB REN (Remote ENable) interface line. |
| ResourceClass | The class of resource for this session (INSTR, INTFC, etc.). (Inherited from Ivi.Visa.IVisaSession) |
| ResourceImplementationVersion | The version of this VISA.NET implementation. (Inherited from Ivi.Visa.IVisaSession) |
| ResourceLockState | The current lock state of the resource for this session. (Inherited from Ivi.Visa.IVisaSession) |
| ResourceManufacturerId | The IVI identification number of the software vendor of this VISA.NET implementation. (Inherited from Ivi.Visa.IVisaSession) |
| ResourceManufacturerName | The name of the software vendor that corresponds to the ResourceManufacturerId property. (Inherited from Ivi.Visa.IVisaSession) |
| ResourceName | The VISA resource name of the currently open resource. This name is the canonical version of the resource name and therefore may vary from the resource descriptor used to open/initialize the resource. (Inherited from Ivi.Visa.IVisaSession) |
| ResourceSpecificationVersion | The version of the VISA.NET specification that describes the functionality provided by this session. (Inherited from Ivi.Visa.IVisaSession) |
| SecondaryAddress | The secondary address of the local GPIB controller used by the given session. |
| SendEndEnabled | Enables/disables sending the END signal on the last byte of a write. |
| SrqState | The current state of the GPIB SRQ (Service ReQuest) interface line. |
| SynchronizeCallbacks | Specifies whether callbacks must be performed in a specific synchronization context. If false, the implementation is allowed to execute callbacks in any context. The default value is true. (Inherited from Ivi.Visa.IVisaSession) |
| TerminationCharacter | The ASCII character used to end reading. |
| TerminationCharacterEnabled | If true, reads end when a termination character is received. |
| TimeoutMilliseconds | The I/O timeout in milliseconds for I/O communication on this resource session. If the timeout is VisaConstants.ImmediateTimeout (0), operations will never wait for the device to respond. If the timeout is VisaConstants.InfiniteTimeout (-1), I/O communication will not timeout. (Inherited from Ivi.Visa.IVisaSession) |
Public Methods
| Name | Description | |
|---|---|---|
 | AssertTrigger | Asserts a software trigger. |
| ControlAtn | Controls the state of the GPIB ATN interface line, and optionally the active controller state of the local interface board. |
| DisableEvent | Disables a client from receiving events of type(s) specified by the eventType argument. (Inherited from Ivi.Visa.IVisaSession) |
| DiscardEvents | Discard all pending events of type(s) specified by the eventType argument. (Inherited from Ivi.Visa.IVisaSession) |
| Dispose | (Inherited from System.IDisposable) |
| EnableEvent | Enables a client to receive events of the type specified by the eventType argument using a WaitOnEvent method. (Inherited from Ivi.Visa.IVisaSession) |
| LockResource | Locks the resource for this session with an exclusive lock, with an infinite timeout. (Inherited from Ivi.Visa.IVisaSession) |
| PassControl | Overloaded. Tells the GPIB device at the specified address to become controller in charge (CIC). |
| SendCommand | Writes GPIB command bytes on the bus. |
| SendInterfaceClear | Pulses the interface clear line (IFC) for at least 100 microseconds. This operation asserts the IFC line and the local interface becomes controller in charge (CIC). |
| SendRemoteLocalCommand | Controls the state of the GPIB REN interface line and, optionally, the remote/local state of the device. |
| UnlockResource | Unlock the resource. (Inherited from Ivi.Visa.IVisaSession) |
| WaitOnEvent | Wait for events of type(s) specified by the eventType argument. (Inherited from Ivi.Visa.IVisaSession) |
Public Events
| Name | Description | |
|---|---|---|
 | Cleared | Occurs when the GPIB controller has been sent a device clear message. |
| ControllerInCharge | Occurs when the GPIB controller has gained or lost CIC (controller in charge) status. |
| Listen | Occurs when the GPIB controller has been addressed to listen. |
| ServiceRequest | Occurs when a service request is received from the interface. |
| Talk | Occurs when the GPIB controller has been addressed to talk. |
| Trigger | Occurs when a trigger interrupt is received from the interface. |
