OPERATION
Network Routing
Not applicable for stand-alone projectors or simple networks with only one type of
controller and linking.
Select "Separate" (factory default) to keep RS232, RS422 and Ethernet
SEPARATE:
messages on their respective paths instead of being broadcast to other types of ports.
This is useful when you have a network in which each projector is connected via both
A
its RS232 and RS422 serial ports (Figure 3.19 )—at each projector, serial
communications will stay on the path of origin only, as determined by the type of
controller. If a projector or path ever fails, you can use the other path.
A, failure
In Figure 3.19 to keep the networks separate would likely cause
B
communication errors. In Figure 3.19 , where there is only one link between any
two projectors (and the controller), make sure to join the networks.
If you have a simple serial network with only one type of linking—RS232 or
RS422—the type of network routing does not matter.

Messages to and from any serial port will also be relayed
RS232 AND RS422 JOINED:
to all other serial ports. Use when there is only one physical link between any two
projectors, but which might be RS232 or RS422.
Messages to and from the RS232 ports will also be
RS232 AND ETHERNET JOINED:
relayed to the Ethernet port, and vice versa. Any RS422 communications will be
isolated.
All messages reach all ports, regardless of type.
ALL JOINED:
