Epson Projector Elp 3000 User Manual

							Connecting to an External Speaker or PA System
For most small-or medium-sized rooms, the projector’s internal speakers are
sufficient. If you need extra amplification for a large room, you can connect the
projector to an external amplified speaker or PA system.
To connect the projector to an external sound system, you need to obtain an RCA-
to-3.5mm Stereo audio cable. You can get one from your computer dealer.
Before beginning, turn off the projector and the speaker or PA system,
1.Connect the cable’s 3.5mm stereo miniplug into the projector’s Audio Out
jack.
2.Connect the RCA plug to the external amplified speaker or PA system. Insert
the cable’s red plug into the R side, and the white plug into the L side.
You should now adjust the Fade menu setting. See page 
39.

							Setting Up Serial Communication
The RS-232C Serial Communication Kit allows your computer and projector
to communicate so you can access the projector menus from your computer
and use the remote control to control your computer. The kit consists of a
cable, a Macintosh adapter, and two software utilities: ELP Link and ELP
Remote Programmer.
Instructions for installing the cable and software are given in the next two
sections. For information on using ELP Link, see Chapters 2 and 3. For
information on the ELP Remote Programmer, see Chapter 4.
By default, the Serial setting in the Options menu is on to enable communication
when the Serial Communication Kit is installed. If, after installing the kit, you
cannot enable communication, make sure the Serial setting has not been turned
off. See Chapter 3 for more information about the menus.Connecting the serial cable
To connect the serial RS-232C cable to your computer and projector:
1.Connect one end of the serial RS-232C cable to the projector’s RS-232C
connector.

							Connecting the Remote Control with the Lead Wire
If you set up the projector for rear projection and want to use the remote control
to control the projector, you need to connect the remote control directly to the
projector with the optional lead wire. You might also need to directly connect
the remote control if anything is blocking the path between the remote control
and the projector.
To directly connect the remote control, connect one end of the lead wire to the
projector’s Remote jack. Connect the other end to the output terminal at the front
end of the remote control. Make sure both ends are plugged in securely.
