Troubleshooting
I cannot access the camera server from a network.
Camera server
● Restart the PC on which the camera server is running.
● Check the Windows NT "Network" settings.
Check that the IP address, subnet mask, gateway and DNS server settings are entered
correctly. Always restart your PC after you change the network settings.
● Check that the Ethernet cable is connected correctly.
Viewer
● Check that the camera server IP address (or host name) is specified correctly.
● If the connection uses the WebView HTTP protocol, you can only penetrate firewalls for access
if the proxy server is set up correctly. Specify an HTTP proxy that uses an ordinary web
browser.
● If the connection uses the WebView TCP protocol, you can penetrate firewalls without using a
proxy. You can set up a TCP proxy, but the proxy must use the WebView dedicated proxy
software. (See P.40 in the Viewer manual.)
Images are not displayed.
Camera server
● Check that the camera is switched on.
● Check that the video cable is correctly connected to the camera and PC.
● If the input port connection position for the video capture board is incorrect, the image is
displayed in blue with the Osprey-100 and in black with Meteor boards. If this occurs, check that
the input port is specified correctly (see P.40).
● To improve the quality of the image, check the image settings (see P.34).
Viewer
● For the helper viewer, check that the viewer has been installed correctly (see P.21).
● For a Java viewer, check operating environment settings such as the web browser version. Visit
the WebView World web page for the latest information. URL: http://www.x-zone.canon.co.jp/

I can't control the camera.
Camera server
● Check that the camera is switched on.
● Check that the RS cable used for camera control is correctly connected to the camera and PC.
● Check that the correct serial port is being used for PC connection and that the serial port in the
server settings panel is correct (see P.39).
● If field of view restrictions are specified, check the settings (see P.44).
● If the VC-C4 camera has been connected using a cascade connection, check that the other
cameras are on and that the RS cable has been connected properly. (If a camera connected in
a cascade connection is Off, it will take approximately one minute after the camera is switched
On until it is ready to use. This also applies when there is RS cable trouble.)
