is lit, it indicates that
power is available to the
EDK (Red LED).
The EDK communication’s
LED has four states:
Off: No signal received
from the reader-controller.
Green: Signal received
from the reader-controller,
and valid encryption key is
available.
Red: Signal received from
the reader-controller, but
no encryption key is
available.
Amber: Communications
problem. May relate to
Pink/Gray/Tan wire
connections or be a
BackEMF issue.
