Collector
State
Description LED Pattern
before moving the "low-visibility" state. 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 915 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 94 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.
■
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 previous test specifications, the reasons for
system failure and possible remedies must be identified before leaving the installation site.
