RS-232 Network
To connect multiple projectors in a network with serial communication, connect the controlling source to the
RS-232 IN connector of the first projector in the network. Then take another serial communication cable and
connect one end to the RS-232 OUT connector and the other end to the RS-232 IN connector of the next
projector. Continue this pattern of connection with all projectors in the network. The last projector in the
network will only have a connection to the RS-232 IN connector. See
232.

"Network Routing" option to "RS-232 and RS-422 Joined". See Section 3 for details.
Then chain the projectors together by connecting an
computer/controller through the
connecting projectors in this manner until you've reached the last projector in the chain, so that only the last
