Figure 2.23. RS-422 Serial Connection to a Computer
Do not use an RS-422 port unless you are using a
computer with RS-422 capability. The voltage levels of
this signal can damage incompatible equipment.

You may wish to use one or more external Marquee Signal Switchers or a third party
switcher in order to significantly increase the number of sources you can select. If
you are using a Marquee Signal Switcher, connect the switcher's RGB output to
INPUT 1
and connect an RS-232 serial communication cable between the switcher and
the projector serial port labeled
communication link (permanently set at 9600 baud) enables you to access inputs
connected to the switcher in the same manner as those connected directly to the
projector. For most other third-party switchers, connect and access sources according
to the documentation provided with that switcher.
NOTE: See 2.4, Source Connections, "Connecting a Switcher" for complete details.

RS-232 NETWORK
: To control multiple projectors with a computer/controller having
an RS-232 interface, first set them all to the same baud rate needed, then chain the
projectors together by connecting the
(already connected to the computer/controller) to the
projector in the chain.
