If you are using more than one Marquee Signal Switcher, daisy-chain the RS-232
switcher inputs/outputs together to form a complete network of inputs accessible
from the projector (you can network up to 9 switchers), and connect Switcher #1 to
the projector as shown in Figure 2.20. In addition, connect the RGB output from each
switcher to its matching slot on switcher #1–for example, connect the RGB output
from switcher #2 to slot #2 on switcher #1, and the RGB output from switcher #3 to
slot #3 on switcher #1. Note that slots used in this manner on switcher #1 are no
longer recognized as inputs to the projector–if you select a slot location that is
connected to another switcher's RGB output, the projector will display the "no input
signal" error message.
Plug the projector's high-current 13-amp rated line cord into the line input socket
located in the lower right corner of the rear panel of the projector, then plug the 3-
pronged end of the line cord into a grounded AC outlet. Input voltage to the projector
must be capable of supplying between 100 and 240 VAC, 50 or 60 Hz. The power
source must be capable of supplying 860 watts of power to the projector. See Section
5, Specifications for all power requirements.
Do not attempt operation if the AC supply and cord are
not within the specified voltage and power range.
Caution: Once the projector is turned off, the lamp cooling fans will continue to
run for approximately five minutes to ensure that the projector and lamp have
sufficiently cooled, at which point the fans will automatically shut off. To avoid
thermal stress to the lamp, never unplug the line cord while the lamp cooling fans are
running. Do not unplug the projector in order to power down.
The projector is set up at the factory for use in a front screen, floor mount orientation.
If your initial installation is ceiling mount or rear screen, displayed images may be
upside down and/or reversed. To correct, you must change the image orientation
from within the Menu
Preferences menu (you may
prefer to do this before
physically installing the
projector in its final
position/orientation).
In the Menu Preferences
menu, highlight and select
the "Image Orientation" pull-
down list. Select from Rear,
Inverted Rear, Front or
Inverted Front according to
your intended installation.
See Section 3, Operation for
further information.
