A Driver Configuration window appears.
From the Card Type drop-down menu, select the driver you want
to register, then key-in the allocated buffer (KB) for the AI, AO, DI,
or DO functions depending on your application requirements.
The allocated buffer represents the size of contiguous, initially
allocated memory for continuous analog input, analog output, digi-
tal input, and digital output. The device driver allocates the mem-
ory size during system startup. The size of initially allocated
memory is the maximum memory size that DMA or interrupt trans-
fer can be performed. An unexpected result occurs when the DMA
or interrupt transfer performs an operation exceeding the initially
allocated size.
