Connecting to a Computer for USB Mouse Control
If you connected your computer to a Computer, USB TypeB, or HDMI (EX3212/EX5210/EX7210) port
on the projector, you can set up the remote control to act as a wireless mouse. This lets you control
computer presentations at a distance from your computer. To do this, connect the projector to your
computer using a USB cable, if it is not connected already.
1. Connect the USB cable to your projector's USB TypeB port.
1 USB TypeB port
2. Connect the other end to any available USB port on your computer.
3. If necessary, configure your computer to work with an external USB mouse. See your computer
documentation for details.

Connecting to a Computer for Sound
If your computer presentation includes sound and you did not connect it using the projector's USB
TypeB or HDMI (EX3212/EX5210/EX7210) port, you can still play sound through the projector's speaker
system. Just connect an optional stereo mini-jack adapter cable (with one 3.5 mm mini-plug and two
RCA plugs).
1. Connect the audio cable to your laptop's headphone or audio-out jack, or your desktop's speaker or
audio-out port.
