• Is an AC adapter (optional) connected to the DC power connector on the WJ-NT104 rear
panel?
• Is the modem power switch turned ON?
• Is the modem cable connected to the RS-232C connector on the rear panel?
• Is PPP selected for NETWORK TYPE in the Network Setup? (Refer to CD-ROM)
• Is a 10Base-T cable connected to the Ethernet connector on the rear panel?
• Is the link indicator of the front panel on?
If it is not on, the unit is not correctly connected to the LAN or the network is not correctly
connected. Check for any poor contact or cable disconnection.
• Is the WJ-NT104 IP address correctly set? (Refer to CD-ROM.)
• Is the wrong IP address accessed? (Refer to CD-ROM.)
If making access from Windows95 or UNIX, check the connection in the following manner.
>ping [IP address set in the WJ-NT104]
If the WJ-NT104 responds to the above command, the connection is correct. If it does not
respond, perform the following procedure:
(1) Initialize referring to MODE SETTING to reset the IP address to 192.168.0.10.
(2) Set the IP address again referring to GLOBAL NETWORK CONNECTION (on CD-ROM).
• Has the set IP address already been assigned to another device? (Refer to CD-ROM)
• Does the set IP address match the conventions of the network/subnet to which the WJ-
NT104 is connected?
WJ-NT104 and client PC connected to the same subnet:
• Are the IP addresses of the WJ-NT104 and the client PC set for the same subnet?
• Is the browser set to [Use proxy server]?
When accessing an NT104 on the same subnet, it is recommended to select [Do not use
proxy server] for the IP address.
WJ-NT104 and client PC connected to different subnets:
• Is the correct value set for the WJ-NT104 default gateway?
• Are power switches of cameras and other connected devices turned on?
• With some WWW browsers or browser versions images may not be updated, camera con-
trol may not function normally, etc. It is recommended to use Netscape Navigator Ver. 4.04
or higher, or Internet Explorer Ver. 4.0 or higher.
• Under conditions such as network congestion or simultaneous access to the WJ-NT104 by
too many users, the display of images may be suspended. In this case, click the [Refresh]
button.
• Enter correct user name and password.
If the correct user name and password are unknown, repeatedly press the [ESC] button on
the screen. If a series of more than one input is accepted, the certification window is not
displayed again.
• Check the actual data transfer rate of the circuit between the modems.
The image rate may be improved in some cases, if the bit rate in the SERIAL PORT SETUP
window it set to a value near the actual data transfer rate.
• Check the contents of the HTML file.
An HTML file is not displayed, if it is incorrectly described or broken.
HTML files may be broken, if they have not been fully initialized. Initialize the files again by
turning on the Mode Setup Switch No. 2 of the WJ-NT104.
• Check the image display mode. Images cannot be saved in push mode.
• According to an announcement by Microsoft, Windows95 may develop trouble if operated
uninterruptedly for more than 50 consecutive days. It is recommended to reset your PC
once a week.
• Image requests may not be made to the WJ-NT104, because data are called from the
cache of the PC. Should this phenomenon occur frequently, it is recommended to set the
browser in the following manner:
For Netscape Navigator
In the [SETTING] menu, set the memory cache and disk cache under [DETAIL-CACHE]
to 0 Kbyte.
For Internet Explorer
In the View drop-down menu of the browser, click Internet Options, and then click Settings
for Temporary Internet Files. Under [Check for newer version of stored pages], mark
[Every visit to the page].
