Controller Board Description
The Card Access System controls access points according to how the inputs and
outputs are defined and correlated with each other. Inputs and outputs are defined
by how the access and control points are wired with the controller.
Before you begin you must establish how you want the outputs to behave as a
function of the inputs. For a complete description of correlation and the modes of
operation see section 2 on page 13.
Keep a record of the wiring for configuration purposes.
