Inherits from I/O Session class.

Long Name Description
GPIB Settings:Line REN State Returns the current state of the GPIB REN (Remote ENable) interface line. Details
VXI/VME Settings:Source Byte Order Specifies the byte order to use in high-level access operations, such as VISA In X and VISA Move In X, when reading from the source. The default is Big Endian (0). Details
Interface Information:Interface Number of Parent Returns the board number of the parent device. Details
GPIB Settings:Secondary Address Returns the secondary address of the GPIB controller used by the given session. If the controller does not have a secondary address, the value of this property is 65535 (0xFFFF). Details
VXI/VME Settings:Window Access Privilege Specifies the address modifier to use in low-level access operations, such as VISA Map Address, VISA Peek X, and VISA Poke X, when accessing the mapped window. The default is Data/Privileged (0). Details
VXI/VME Settings:Destination Access Privilege Specifies the address modifier to use in high-level access operations, such as VISA Out X and VISA Move Out X, when writing to the destination. The default is Data/Privileged (0). Details
Register Based Settings:Source Increment Count Specifies the number of elements by which to increment the source address on block move operations. Valid values include 0 and 1. The default is 1. If this property is set to 0, VISA Move In X operations always read from the same element, essentially treating the source as a FIFO register. Details
GPIB Settings:Primary Address Returns the primary address of the GPIB controller used by the given session. Details
VXI/VME Settings:Destination Byte Order Specifies the byte order to use in high-level access operations, such as VISA Out X and VISA Move Out X, when writing to the destination. The default is Big Endian (0). Details
Register Based Settings:Window Base Address Returns the base interface address to which this window maps. If the Window Access property is Not Mapped, the value of this property is meaningless. Details
Register Based Settings:Window Access Returns whether the current session has a mapped window, and if so, whether the window allows direct pointer dereferences. Details
General Settings:Allow DMA Transfers Specifies whether I/O accesses should attempt to use DMA (TRUE) or Programmed I/O (FALSE). In some implementations, this property may have global effects even though it is documented as a local property. This behavior affects performance and not functionality. Details
VXI/VME Settings:VXI Logical Address Returns the logical address of the local VXI controller. Details
Register Based Settings:Destination Increment Count Specifies the number of elements by which to increment the destination address on block move operations. Valid values include 0 and 1. The default is 1. If this property is set to 0, VISA Move Out X operations always read from the same element, essentially treating the destination as a FIFO register. Details
VXI/VME Settings:Source Access Privilege Specifies the address modifier to use in high-level access operations, such as VISA In X and VISA Move In X, when reading from the source. The default is Data/Privileged (0). Details
Register Based Settings:Window Size Returns the size of the region mapped to this window. If the Window Access property is Not Mapped, the value of this property is meaningless. Details
VXI/VME Settings:Window Byte Order Specifies the byte order to use in low-level access operations, such as VISA Map Address, VISA Peek X, and VISA Poke X, when accessing the mapped window. The default is Big Endian (0). Details
