Simultaneous Input/Output Using the
Simul AI/AO Buffered (Legacy MIO) VI
Because legacy MIO-type boards have only one clock available for signal
acquisition (scan timing) and generation (update timing), the same clock
is used for both. The acquisition uses
counter 2
by default. The
generation is set up to use the I/O connector at the
clock source
input to the
AO Start VI. Because the I/O connector
scan clock
input is the OUT2 pin,
which already has the acquisition timing signal on it, no external clock
wiring is required. The result is that the waveform acquisition and
generation start simultaneously and occur at the same rate using the same
clock. Your waveform generation occurs at the same rate as the scan rate
you choose for waveform acquisition.
