Table 8. Yellow Comm LED
LED activity Explanation
LED is off continuously The controller is not detecting any
communication (normal for stand-
alone applications).
LED blinks The controller detects communica-
tion (normal for communicating
applications, including data sharing).
LED is on continuously 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).
