operated with the keypad, the lens barrel of a motorized zoom lens rotates to adjust the size of the image without moving the projector. minimum and maximum image sizes depend on which zoom lens is installed. see section 5, specifications.
focus
operated with the keypad, focus adjusts the sharpness of the image at the current throw distance.
lens offset
operated with the keypad, vertical and horizontal offsets shift the lens and move the image up or down and left or right. see section 2, installation and setup and section 6, specifications for ranges and other details.
shutter and iris
operated with the keypad, closing the internal shutter blocks the lens internally and turns the image to off (black). enlarge the diameter of the iris—a.k.a. optical aperture—for optimized brightness; reduce the diameter to optimize contrast ratio.
eyebolts
1 2 eyebolts on bottom (factory-installed)—for attaching safety cables when hoisting inverted projectors.
2 4 eyebolts for top (separate)—for non-inverted hoisting. note: 2 additional safety eyebolts required.).
handles
for brief hand transport only. not used for hoisting, rigging, or as safety points.
stacking mounts / stacking legs
optional on mirage s+.
for stacking up to 3 projectors. see section 2 for details.
use christie stacking mounts only.
adjustable feet
turn the 4 adjustable feet to increase or decrease height and/or tilt as needed. for most installations the projector will likely be slightly inclined to match the screen tilt–this reduces the amount of vertical offset required. see 2.3, projector position and mounting
filter door
louvered grille for air intake. remove to access and replace air filter.
lamp door
louvered/vented door for accessing and replacing the lamp module. note: lamp replacement requires a qualified service technician.
input panel
the input panel the projector to inputs (sources) and controllers such as pcs.
1 composite/s-video input - accepts a composite video and s-video signal from devices such as vcrs.
2 rgb input - accepts rgb and sync signals from devices such as computers, as well as composite video, s-video or ypbpr component signals.
3 rs232 serial interface (with loop through) - allows one or more projectors to be remotely controlled by a computer or controller,
4 rs422 interface - allows one or more projectors to be remotely controlled by an rs422 compatible computer or controller (such as the two-way controller accessory). the first projector can be connected by the rs422 port and then the successive projectors, by the rs232 interface. rs422 communications can travel greater distances than can rs232 communications, but require rs422 compatible equipment.
ac power input and monitoring
ac line cord input - use the ac supply specified, and always use the line cord provided with the projector. see section 5. never unplug while the fans are running.
do not attempt operation if the ac supply is not within the specified voltage and power range. use the specified line cord.
1 voltmeter - displays incoming voltage level reaching the projector.
2 switch/breaker - the breaker on the rear panel serves two purposes: 1) it is a power switch for the ballast 2) it protects against excessive conditions 15a or more for roadster s+12k, and 20a or more for roadsters+16k/mirage s+14k). if the projector is faulty or excessive ac is detected, the breaker will “trip” to off in order to prevent damage. try moving the breaker on again - if the breaker continues to trip off, this indicates a major fault and the ac problem must be resolved. possible causes might include shorts, damage to lamp cables, or very excessive ac.
two status displays:
1 2-digit status/error code window - this led (light emitting diode) is adjacent to the built-in keypad. during normal operation, the "power" light is steady yellow and indicates “on”. when the status of the projector changes, the led displays a 2-digit code number representing the projector’s new status. in addition to the numeric readout, there are two decimal points in the display: the right decimal point flashes when the projector receives a command, and the left point flashes when the projector sends a command.
2 lcd status display window - displays a text message describing the current system status (such as an error). during normal operation, this display indicates power on and includes the frequencies of the vertical and horizontal syncs. the display also shows if the on screen display (osd, or menu system) is on or off. the lcd displays the message power off when the breaker is on, but the lamp is off.
keypads / sensors
1 wired remote keypad connector - for optional tethered remote control of the projector.
2 built-in keypad - alternative location for working with the projector.
3 infrared sensors - the infrared (ir) sensors on the front and rear of the projector receive infrared signals from the ir keypad for remote control of projector functions. for proper operation, make sure that these sensors are not blocked.
