Automatic Serial Polling

The NI-488.2 software supports automatic serial polling of devices when the GPIB Service Request (SRQ) line is asserted. Check the Automatic Serial Polling checkbox to enable or disable automatic serial polling. Positive poll responses are stored and can be retrieved with the ibrsp function. This feature usually does not conflict with any device that conforms to the IEEE 488.1 standard. If a conflict exists with a device, make sure the Automatic Serial Polling checkbox is not checked. By default, automatic serial polling is enabled.
