39 Troubleshooting
39.1 Introduction
Several web browser settings are relevant to the proper
functioning of the configuration web pages of the
Praesideo system. The most important ones are the
security settings and connections settings. Note that
these settings can also be modified or limited by the
network administrator, who is responsible for the
network and/or PC that is used for configuring the
Praesideo system.
39.2 Security settings
Security settings can prevent for example the execution
of the SVG viewer in Internet Explorer, which is
needed to display the equalizer response on the web
page. The preferable solution is to add the Praesideo
system to the list of the trusted sites, by entering the IP-
number of its network controller. This list can be found
via Start > Control Panel > Internet Options....> Security >
Sites. Here, you can also lower the protection level for
these trusted sites. The protection level for non-listed
sites is not affected.
39.3 Connections
The Local Area Network settings (Start > Control Panel >
Internet Options....> Connections > LAN Settings…) can
influence the ability to fully access the Praesideo system.
Because of security considerations Praesideo only
accepts one connection at the same time. When a Proxy
server is used, it can not be guaranteed that always the
same connection will be used. Therefore the address of
the Praesideo system should be defined as local address
in the Proxy server configuration. This is typically done
in the configuration script provided by the network
administrator, or the Proxy server should be disabled
altogether.
Other possible sources of problems are virus checkers,
popup blockers, anti spyware software and firewalls. Try
to disable this type of software during the Praesideo
configuration or configure it in such a way that it accepts
the Praesideo system as a trusted site.
