PCI-2513 block diagram

Figure 3 is a simplified block diagram of the PCI-2513. This board provides all of the functional elements
shown in the figure.
Synchronous I/O – mixing analog, digital, and counter scanning
The PCI-2513 can read analog, digital, and counter inputs, while generating digital pattern outputs at the same
time. Digital and counter inputs do not affect the overall A/D rate because these inputs use no time slot in the
scanning sequencer.
For example, one analog input channel can be scanned at the full 1 MHz A/D rate along with digital and counter
input channels. Each analog channel can have a different gain, and counter and digital channels do not need
additional scanning bandwidth as long as there is at least one analog channel in the scan group.
