LEDs on the EX2 expansion module
Explanation
Power is on (normal operation).
The auto-wink option is activated, and the
controller is communicating.
Flash download is being received.
Either the power is off or the controller has
malfunctioned.
Explanation
The controller is not detecting any communica-
tion (normal for stand-alone applications).
The controller detects communication (normal
for communicating applications, including data
sharing).
An abnormal condition that may occur during
discovery. The LED may flash fast enough to
look as if it is on continuously. If this LED activity
occurs at any other time, the site may have
excessive radio frequency interference (RFI).
