Madrigal Imaging MP-8, MP-9 manual Optical Alignment, Step

INSTALLATION & SETUP

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 RS-232 serial port labeled “OUT” is provided for projector networking applications.

2.8Optical Alignment

Optical alignment is required when the throw distance changes or the pro- jector 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.

	To access and use the Guided
	Mechanical Setup tutorial, turn on
	the projector ( POWER ) then press HELP
	at operation level. The Help menu
	is displayed. Next press 2 to select
	Guided Mechanical Setup. The first
	page of the guide will be displayed on
	the projection screen. When using
	the guide, press HELP to display the
	next page, press RECALL to display the
	previous page. When complete, press
	EXIT to end Help.
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.
