RS-232 Network
To control multiple projectors with a computer/controller having an RS-232 interface, first set all projectors to
the same baud rate as the controller, then chain the projectors together by connecting the
RS232 OUT
connector of the first projector (already connected to the computer/controller) to the
RS232 IN
connector of
the next projector in the chain. Continue connecting projectors in this manner until you've reached the last
projector in the chain, so that only the last projector has an unused
RS232 OUT
port. See
Figure 2-36
.

RS-422 Network
To control multiple projectors with a computer/controller having an
RS-422
interface, first set them all to the
same baud rate as the controller, then chain the projectors together by connecting an
RS-422
port of the first
projector (already connected to the computer/controller) to an
RS-422
port on the next projector in the chain.
Use any of the two
RS-422
ports available on the projector. One is located at the rear (6-pin XLRs) and one is
on the side Input panel (9-pin D-connector). Continue connecting projectors in this manner until you've
reached the last projector in the chain, and so that only the last projector has one unused
RS-422
port.
