When you begin troubleshooting a system, you do not yet know the source of
the problem. You should suspect all parts of the system (communications,
power, repeaters, base station, software, LoggerNet computer station issues)
until you determine what went wrong. Use the clues given by the problem to
narrow your focus. However, you may need to broaden your focus from time to
time if causes of the problem fail to emerge.
Sometimes the problem is caused by intentional changes to the system,
sometimes it is caused by unintentional changes to the system. Sometimes
problems are caused by acts of nature (lightning strikes, storms, animal
intrusion), and sometimes operational features of the station had problems that
changed gradually and remained undetected until they finally ceased to
function (bad battery, etc.). An on-site camera can be helpful if physical
problems occur with on-site equipment on a regular basis.
It can be helpful to review the key installation sections of this manual (Section
8 , Installation of Individual CRVW3 Stations
(p. 15)
, and Section 10 , Complex
(Large) Radio Networks
(p. 58)
) with a “problem identification” perspective.
This can trigger ideas about things that can be investigated.
You should perform whatever troubleshooting work is possible from the
lab/office before travelling to the field. Once all remote LoggerNet options
have been tried, plan a visit to the field to investigate the station or problem
area directly.
13.1 Troubleshooting Problems Remotely Using LoggerNet
Sometimes you can still communicate with the CRVW3 station, but its
measurements don’t seem to make sense or work only intermittently. In those
cases, you can connect to the station and check the spectrum to see if there is a
sensor problem (sensor cabling, connectivity, operation, noise/interference).
See Section 12.1.2 , Sensor Spectrum Checks
(p. 97)
, for details about how this is
done. Compare the current spectrum with a baseline spectrum saved during
maintenance or installation. A visit to the site may still be required, however
the spectral information may give a clue about what has gone wrong.
PakBusGraph is an excellent tool for troubleshooting stations and how they
communicate with each other. Refer to Section 11.3 , Station Health
Monitoring
(p. 93)
, or Section 6.4 of the
LoggerNet
manual for more
information.
LoggerNet also has a LogTool utility that shows low-level text messages about
how LoggerNet is operating and attempting to connect and interact with
CRVW3 stations. These logs can be captured and sent to your support
representative for evaluation. LoggerNet also has a TroubleShooter utility that
helps to identify communication problems. For more information about using
these tools, refer to Section 6 of the LoggerNet manual.

In an RF451 network of CRVW3 stations, you can perform radio diagnostics
by visiting the base station and using the RF DIAG connector of the
base/master radio. Use the appropriate cable (pn 20625) and run the included
software.
