Tips for Better Networked Projection
■ Avoid Exceeding Connection Limits
The maximum number of computers and projectors that can be connected varies
by mode. When this limit would be exceeded, it is not possible to add computers or
projectors to a session. Thus, if the total number of computer users requesting to
join a session at the same time would exceed the limit, their requests may be
denied. In this case, an error message is displayed on the computers that could not
join the session.
Similarly, if the total number of projectors users attempt to add to a session at the
same time would exceed the limit, their requests may be denied. In this case, a
message is displayed on computers that could not add projectors, indicating that
the projector list has been updated.
■ Operation if Devices Are Disconnected
If the connection is lost (for example, if a LAN cable is accidentally disconnected),
the affected computer or projector leaves the session. Disconnection of essential
computers or projectors will terminate a session.
For example, in Classroom Mode, disconnection of the presenter’s computer will
terminate the session.
■ If Projectors Cannot Be Detected
If projectors cannot be detected or no image is displayed (except for the cursor)
when you are attempting to connect to projectors in other subnets in Broadcast
Mode, make sure the router supports multicast routing. Routers that do not support
IPv4 multicast routing cannot be used to connect to projectors in other subnets in
Broadcast Mode. Note that the router must be set up to route multicast addresses
used by the application.
In Broadcast Mode, the following message is displayed if no signal is received from
computers for 30 seconds. The projector IP address and name are shown in the upper
left.
