Symptoms Possible causes Remedial actions
The Power indicator is not
constantly lit, or the Net
indicator is not flashing
randomly.
Faulty cabling. To verify that the cables work, ping the address of a known
existing unit on your network.
If the cabling is OK and your network is reachable, you
should receive the following reply:
...bytes = 32 time = 2 ms,
or something similar.
The Snapshot and Net
indicators are flashing
every 0.5 seconds
Hardware failure. Contact your Axis dealer.
Your AXIS 200 works
locally, but not externally.
Firewall protection Check the Internet firewall with your system manager.
Default routers required Check whether you need to configure the default routers
settings.
The Internet site is too
heavily loaded.
Use a script running on your web server to relay images
from the AXIS 200 to the Internet. This is particularly impor-
tant when generating zoom and hugesize images.
No image using Refresh
and/or
Slow updating of
snapshots using
Server Push
Complex images, i.e.
those containing great
picture contrasts, have
greater filesize and thus
place greater demand on
the available file space
within the AXIS 200.
The memory constraints become significantly more acute if
the same snapshot is accessed by multiple clients.
Try limiting the number of clients.
Triggering Difficulties with
CRON scripts
Unable to triggering on
both positive and nega-
tive transitions of the Con-
trol Button and/or IO
(double-edged trigger-
ing).
Repetitive trigger conditions occurring in quick succession
of one another, maybe missed. This is because the com-
mand initiated by the first trigger event may not have been
fully executed prior to the second event occurring. This sce-
nario is demonstrated in the illustration below:
This feature has particular significance when using com-
mands that take a relatively long time to process, e.g. email,
ftp, especially if they are conjugated with a loop statement.
