The digital routing circuitry has the following functions:

  • Manages the flow of data between the bus interface and the acquisition/generation sub-systems (analog input, analog output, digital I/O, and the counters). The digital routing circuitry uses FIFOs (if present) in each sub-system to ensure efficient data movement.
  • Routes timing and control signals. The acquisition/generation sub-systems use these signals to manage acquisitions and generations. These signals can come from the following sources:
    • Your C Series modules
    • User input through the PFI terminals using parallel digital C Series modules
  • Routes and generates the main clock signals for the cDAQ chassis. To determine the signal routing options for C Series module(s) installed in the cDAQ chassis, refer to the Device Routes tab in MAX.
