ISA Version: Software only

Event notification:
The PCI versions of these boards support concurrent analog input and output scans. That is, these boards
allow for operations of analog input functions (
cbAInScan() and cbAPretrig()) and analog output functions
(
cbAOutScan()) to overlap without having to call cbStopBackground() between the start of input and output
scans. Equivalent UDR Library for .NET methods are
AInScan(), APretrig(), AOutScan()and
StopBackground().
