3M Multimedia Projector MP8030

Next, find the AUDIO OUT terminals on your VCR or other audio source. Insert the left and right audio cable

connectors (Figure 3-7) to the input source, and connect the other end to the AUDIO-L and AUDIO-R

terminals on the MP8030.

Figure 3-7. 3-Conductor Video/Audio Input Cable

Use the Audio-Out terminal to disable the MP8030 speaker and channel sound to external speakers. The

remote control VOLUME and MUTE buttons will control the external speaker volume levels. If you are

giving a multimedia presentation that is complete with stereophonic sound, then you may want to consider

connecting your audio source to a high-quality stereo system. Of course, if you route your audio cables this

way, the MP8030 audio controls (VOLUME and MUTE) will not function.

RS-232 Mouse Control Connection (IBM Compatibles)

The MP8030 projector has an RS-232 connector (Figure 3-8) that

allows IBM compatible serial mouse emulation.

To emulate a serial mouse:

a. Power down the MP8030 and PC computer

b. Connect the RS-232 cable to the PC mouse serial port and MP8030 Control connector

c. Power up the MP8030

d. Power up the PC

e. If the PC has an internal pointing device, it must be disabled (refer to your owners manual for

instructions)

f. After the pointing device is disabled, reboot the PC and the operating system (DOS, Windows)

should recognize the MP8030 stick switch as the pointing device

3-2. Projector SetUp

The meeting room is your operating environment and any stray light hitting the projection screen will become

glare. It is best to use a meeting room without wide-open windows. If there are “light stripes” from venetian

blinds, try to find a viewing area that’s away from them—and remember, the light stripes will move as the

hour changes.

Note

Whenever you have a choice, light the room from the rear, away from the projection screen. The

MP8030 has a brightness adjustment to achieve the best image possible.

Distance to Viewing Screen

The 3MMultimedia Projector MP8030 can be used in a small or large meeting room to project a quality

image from 46 cm (18 in.) to 762 cm (300 in.) in size. The distance between the projector and the viewing

screen (see “a” in Figure 3-10) and the zoom lens setting (minimum to maximum) will determine the size of

the projected image. Refer to the table in Section 9-2 to determine how far away from the viewing screen you

need to place the projector to fill the screen with the projected image.

Remember that increasing the projector-to-screen distance also decreases the image’s brightness dramatically.

In other words, as the image grows larger, it also grows dimmer. For best results, experiment to find the right

combination of projector-to-screen distance and room lighting.
