error Message
Description
FPGA2 failed
If the transceiver detects a hardware fault, it sends a warning message to the
display equipment and switches to the Degraded state of operation.
Degraded
(Low power)
The transceiver continuously runs background performance checks on forward
power, reverse power, receiver sensitivity and temperature. If any of these
parameters falls outside predetermined levels a warning message is sent to
the Radar Distribution Unit indicating the nature of the fault.
The transceiver continues to operate, but with reduced performance and
functionality.
Caution: As a result of reduced output power, range performance will be
reduced and the system may not meet the expected operational detection
performance.
Fault
If the performance or functionality is degraded such that the transceiver cannot
operate it enters the fault state and a fault message is sent to the display
equipment.
The transceiver stops radiating RF and there is no video output to the Radar
Distribution Unit.
A spurious fault may be cleared by re-powering the equipment.
Communication
error
If communication is lost between the Radar Distribution Unit and the

, the RDU reboots the SharpEye leading to a potential 60 second
gap in coverage.
