infoValue Description
ND_AUTOMATIC
Lets NI-DAQ decide the type of FIFO interrupt
based on the acquisition rate. This is the default.
ND_INTERRUPTS
NI-DAQ uses interrupts for data transfer
ND_INTERNAL_TIMER
Counter 1 uses the internal timer as the source for
its CLK1 source
ND_INTERRUPT_EVERY_SAMPLE
Generates interrupts on every sample regardless of
the acquisition rate
ND_INTERRUPT_HALF_FIFO
Generates interrupts only when the FIFO is half
full, regardless of the acquisition rate
ND_IO_CONNECTOR
Counter 1 uses the CLK1 signal from the I/O
connector as the source for its CLK1 signal
ND_NONE
Cancels the effects of having accidentally called the
SC_2040_Config function
ND_NO_STRAIN_GAUGE
Disables the SC-2043-SG accessory
