Collector State
Description
LED Pattern
No Battery The collector has determined it
should have a backup battery, but
that battery does not appear to be
present or is not functioning. The
display of this state is a higher
priority than all states other than
Low-visibility, and will be
displayed exclusively if the battery
cannot be detected.
Morse code for the letter ‘S’ ( . . . )
Ok The radio processor has booted
and is reporting end-point
messages to the host processor,
and the collector 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
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 the collector is running
(does not imply that end-points are
still being read or 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 the antenna functions within acceptable tolerances at your
installation site. Refer to the Antenna Line Sweeps Procedure on page 83 for testing
details.
This test should be performed using the following conditions as a guide:
• Beginning Frequency: 902
• Ending Frequency: 928
• VSWR Expected Results: 1.5:1 or less for the specified frequency band.
• Return Loss: Must be –14dB or better for the specified frequency band.
• 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.
