CCU State
Description
LED Pattern
Ok The radio processor has booted and is
reporting end-point messages to the host
processor and the CCU has established an
authenticated connection to the head-end. This
condition will be signaled for about 15 minutes
before moving the "low-visibility" state.
Morse code for the letter sequence ‘BN’ ( _ . .
. _ . ) The dit and dah timing described above
with the space between the ‘B’ and the ‘N’
characters being 660 ms.
Token Received If the radio reports decoding a "magic" token
which would enable the WiFi diagnostic
interface this pattern is presented for one 10
second interval. This condition is higher
priority than the Lo-visibility and the missing
battery indications.
Morse code for the number ‘5’ ( . . . . . ).
Low-visibility After 15 minutes in the "Ready" state the LED
pattern changes to the "Low-visibility" mode
which indicates that the CCU is running (does
not imply that end-points are still being read or
that head-end communications are still
possible.
10 ms illumination every 30 seconds.
Performing an Antenna Sweep Test
If the 900 MHz antenna is remotely mounted for your installation, an antenna sweep test
must be performed to verify that the antenna functions within acceptable tolerances at
your installation site.
This test should be performed under the following conditions:
• Beginning Frequency: 902
• Ending Frequency: 928
• VSWR Expected Results: Must be 1.5 or less for the specified frequency band.
• Return Loss: Must be –18dB or better for the specified frequency band. Any
deviations from this return loss warrant further investigation.
• Test Point: Feed line connected to the antenna at the top; test from the lightning (or
surge) arrestor to the antenna port.
• Results: Test results must be saved in. PDF format.
• Test Gear: Current and proper calibration; be sure that calibration is turned on during
the test. A qualified operator of the test equipment must perform the test.
Note If the system does not perform to the above test specifications, the reasons for
system failure and possible remedies must be identified before leaving the
installation site.
