User manual OPTOMA BX-AL133

[. . . ] Should it be necessary to move the sled by hand, make sure it is done slowly and lightly. The Optoma motorized sled will ramp up and down at the beginning and end of the traversal to minimize swaying forces at the mount. As the motor accelerates and brakes, there is a minimal change in the sound. This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. [. . . ] The edge of the adaptor plate will land about a half-inch from the motor housing side of the sled. If the bracket is in front of the projector lens, proceed to the next step (Verify centering). If the bracket is not in front of the projector lens, you will need to change the setting. Simply press the LENS OUT button on the remote, and wait for the bracket to move in front of the projector lens. The sled will confirm the new setting by moving the bracket away from the projector lens to the new LENS OUT location. The edge of the adaptor plate will land about a half-inch from the motor housing side of the sled. This setting will be preserved in the unit even if it is unplugged or undergoes a power failure. To change back, just repeat the above procedure. Rear Panel View OFF ON +9V DC In +12V Trigger Out +12V Trigger In Remote IR Sensor In LENS OUT LENS IN PANEL OFF PANEL ON SLOW FAST 2. If needed, make small adjustments (+ or ­ a quarterinch) to the lens bracket after disconnecting the power, by loosening the screws and sliding the bracket to the left or right as needed to achieve centering. The optical sensors will stop the edge of the lens adaptor plate approximately a halfinch from the housing on either side of the sled. You can use this gap on the motor or the pulley side for fine-tuning adjustments. Projector Lens For more information, please visit our website at: http://www.

Using the remote, test run LENS IN and LENS OUT commands. Tighten Knobs 4. Configuring the lens speed The lens has two operating speed modes ­ FAST and SLOW. The slow mode reduces the inertia exerted by the lens on the mounting system by accelerating and decelerating very slowly, and by limiting the top speed of the lens as it traverses the sled. Follow the projector or scalar instructions to configure the lens trigger. The Trigger-In (tip positive) operates as follows: +12V LENS IN command 0V LENS OUT command NOTE: The input trigger jack may be temporarily overridden by the remote control. When the next transition of voltage occurs (up or down), the trigger will take control once again. Another option allows you to use the +12V Trigger-Out jack on the rear of the device. The output jack is set to +12V whenever the sled is in the LENS OUT position. This is typically used for triggering screen masking systems to mask the side of the screen when an HDTV (16:9) image is being projected instead of a widescreen (2. 35:1) DVD movie format. The Trigger-Out jack (tip positive) operates as follows: 0V Lens is in the LENS IN position +12V Lens is in the LENS OUT position Each sled is supplied with an optional remote IR sensor which may be used to improve reception if the sled is located where IR signals cannot be reached. [. . . ] Turn the projector on and project a full, yet still 16:9 image from the projector. Carefully install the lens and adjust the tilt to equalize the top and bottom image geometry while positioning the lens vertically to center the output beam. Position the motorized mount on the bottom side of the lens plate so that the six holes (refer to the diagram on the previous page) in the lens plate line up with the six holes in the flat side of the motorized mount. Insert the four small 1/4" screws through the four small holes of the lens plate into the motorized mount and tighten. [. . . ]
