Remedy
Use the following procedure to
check for unique IP address
assignments:
1 Enter the following at an MS-
DOS prompt (command
prompt):
ping <host name or
IP address of video
network station>
2 The cause of the problem
can be determined from the
response received:
• bytes=32 time=2ms ...
The IP address has already
been assigned. Please
obtain and set another IP
address.
• destination host
unreachable
The video network station
is not on a reachable
network node. Please
obtain and set another IP
address.
• request timed out
The IP address has not
been assigned to any
users. It can be assigned to
the video network station.
Confirm that the supplied AC
adapter is connected.
Limit the number of users who
can access the video network
station to those who need to
monitor. Registering users and
setting user passwords is
recommended.

Remedy
Confirm that the network cable
is connected correctly by the
following procedure:
1 Execute a "ping" command
to an existing host on the
network.
2 If a response such as
"...bytes=32 time=2ms" is
received, the cables are
connected properly.
Contact your system
administrator.
Check whether a default router
setting is required.
Prepare a script to run on the
Web server and replay images
sent from the video network
station to the Internet.
If several clients attempt to
access the same image at the
same time, memory limitations
may degrade server
throughput. Try reducing the
number of clients.
Change the computer display
setting to a minimum of 65,000
colors (16 bits). Poor image
quality will result if the display
is set to 256 colors or less.
