Each board needs a variety of constants loaded before it will operate properly. The code to do this loading is integrated into the online system, and the actual constant values that are loaded reside in the "Constants Database".
To explore these constants use Huberts web based constants browser.
Various trigger constants relevant to L1D crate operation are documented below:
