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. 275 Networked Multi-Projection Functions in All Modes
