Cause/solution
• Is the Ethernet cable firmly connected to the 10BASE-T,
100BASE-TX, or 1000BASE-T port on the rear side?
Confirm the cable is firmly connected.
• Is the connection indicator of the network port lit on the
rear side?
When it is not lit, connection to a LAN is not estab-
lished or a network is not working correctly.
Confirm that the connection indicator of the network
port is lit. Refer to the system administrator if it is not
lit.
• Is the valid IP address set?
Refer to a system administrator for further information
about the settings.
• Are you accessing the wrong IP address?
Check the connection by using a ping command from
the PC command prompt as follows.
>ping "IP address of this unit" If there is reply from this
unit, the connection is normal. If not, check the set-
tings of the IP address and the subnet mask.
• Is the same IP address provided to other devices?
Refer to a system administrator for further information
about the settings.
• Are there contradictions between the address and the
network subnet to be accessed?
When the recorder and the client (PC) are on the same
subnet, is the same subnet set for the IP addresses of
the recorder and the PC? Or is "Use Proxy Server" for
the settings of the browser checked? When accessing
the recorder in the same subnet, entering the address
of the recorder in the "Don't Use Proxy For These
Addresses" box is recommended.
• Depending on the traffic of the network, there might be
difficulties in displaying images. Press the [F5] button
on the keyboard to request images.
• Isn't the network traffic heavy?
These symptoms may occur when the network traffic
is heavy.
• It may be possible that a pop-up blocker other than
Internet Explorer is activating. Check the installed soft-
ware and cancel the pop-up blocker.
• Are the correct user name and password entered?
Confirm the correct user name and password.
• When playing images recorded at a higher frame rate,
audio may sometimes be played interrupted.
• When any setting of the setup menu has been changed
during the download, the download will be canceled
automatically. In this case, the downloaded file is not a
complete file and it is impossible to play it.
