Basic I/O Services
The VISA Instrument Control Resource lets a controller interact with the device that it is associated with by providing the controller with services to do the following:
- Send blocks of data to the device
- Request blocks of data from the device
- Send the device clear command to the device
- Trigger the device
- Find information about the status of the device
 |
Note For the ASRL INSTR and TCPIP SOCKET resources, the I/O protocol attribute must be set to VI_PROT_4882_STRS to use viReadSTB() and viAssertTrigger(). |
The following topics describe the operations provided by the VISA Instrument Control Resource for the Basic I/O Services.
