DAPL Commands

The DAPL system accepts commands for device independent configuration for input sampling, output updating, and data processing that run concurrently. The data processing commands covered here are provided by the DAPL system, but the Developer's Toolkit for DAPL can be used to create new processing commands. The controls technology pages and DSP technology pages suggest some possibilities.

DAPL commands can be organized into the following categories. For an alphabetical list of the commands, download the DAPL PDF (1.27MB) manual.
