The Network indicator
displays red.
Faulty cabling. 1. To verify that the cables are functional, PING the address
of a known existing unit on your network.
2. If the cabling is OK and your network is reachable, you
should receive the reply similar to this:
...bytes = 32 time = 2 ms,
The Active and Network
indicators are flashing
every 0.5 seconds
Hardware failure. Contact your Axis dealer.
Your AXIS 2400 works
locally, but not externally.
Firewall protection Check the Internet firewall with your system manager.
Default routers required Check if you need to configure the default router settings.
The Internet site is too
heavily loaded.
Use a script running on your web server to relay images
from the AXIS 2400/2401 to the Internet.
No image using Refresh
and/or
Slow updating of
snapshots using the
Server push function.
Complex images, i.e.
those containing great
picture contrasts, have
greater file size and thus
place greater demand on
the available file space
within the AXIS
2400/2401.
The memory constraints become significantly more acute if
multiple clients try to access the same snapshot.
Try limiting the number of clients.
Triggering difficulties with
programming scripts
Unable to triggering on
both positive and negative
transitions of the Control
Button and/or IO ports
(double-edged trigger-
ing).
Repetitive trigger conditions that occur in quick succession
of one another can be missed. This is because the com-
mand initiated by the first trigger event may not have been
fully executed prior to the second event. This scenario 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. mail
or ftp, especially if they are conjugated with a loop state-
ment. See also Appendix H- The Programming Script.
Bad snapshot images. Display configured incor-
rectly on your worksta-
tion.
Within Display Properties, configure your display to show at
least 65'000 colors, i.e. at least 16-bit.
Using only 16 or 256 colors on your computer will produce
dithering artifacts in the image.
