INSTALLATION & SETUP
If using the projector with a signal switcher, connect an RS-232 serial communication
cable between the switcher and the projector serial port labeled ''SWITCHER''. lf the
projector is to be controlled by a computer or controller which has an RS-232 serial port,
connect an RS-232 serial cable between the computer and the projector serial port labeled
''IN''
. After the connection is made, set the serial port baud rate as described in the
Projector Setup entry in section 3.7, Utilities.
Notes: 1) All serial connections require a 9 pin D connector at the projector end. Refer to
Appendix D for cable wiring requirements. 2) For computer/controller control, PC
software is required. 3) The RS232 serial port labeled ''OUT'' is provided for
projector
networking applications.
2.8 Optical Alignment
Optical alignment is required when the throw distance changes or the projector cannot be
focused using the focus controls. The projector is optically aligned at the factory at a
fixed screen size and a fixed projector-to-screen distance. See Appendices F and G for
the specific details needed for your projector model and lens. If the throw distance has
changed since the last setup, proceed as follows:
Notes: 1) The projector must be warmed up for at least 45 minutes prior to performing
optical alignment. 2) Optical alignment is both a mechanical and electrical adjustment.
Electrical adjustments are stored in the current setup memory. After alignment is
complete, setup memories which were previously set up (if any) must be set up again.
Memory setup is explained in section 2.10. 3) Factory alignment is performed using the
internal crosshatch with a 61.8 kHz signal applied.
It is recommended that optical alignment be performed using the projector's Guided
Mechanical Setup tutorial. This tutorial displays step-by-step instructions during the
alignment. The instructions in this section require use of the Guided Mechanical Setup
tutorial.
Step 1 >
If you have not already done so, calculate the throw distance and set the projector
position as explained in section 2.4,
Mounting. Turn power off before moving the
projector.
