The attached examples are for Delta Sigma C Series Modules and SAR ADCs / Slow Sampled Modules.* The SAR ADCs / Slow Sampled modules can be used in Star or Daisy-Chain configurations. The Delta Sigma Modules can only be used in a Star configuration with NI-DAQmx 9.6. NI-DAQmx 9.6.1 and later versions add support for Daisy-Chain configurations with Delta Sigma Modules.
