If your network includes a wireless router, users can connect to the projector wirelessly from computers (using
EasyMP Network Projection software). A USB cable must still be connected from the computer to the projector
for annotating from a computer interactive application. Users can also connect wirelessly from an iPad,
iPhone, or iPod touch using the optional Epson iProjection™ app. When the projector is connected to these
devices, only the built-in toolbar is available (single pen support).
If the projector is not connected to a network (or the network does not include a wireless router), you can
purchase the optional wireless LAN module for the projector. This will allow wireless projection directly from a
computer to the projector and use of the built-in interactive toolbar.
You can purchase the optional wireless LAN module (part number V12H418P12) from an Epson authorized
reseller. To find the nearest reseller, call 800-GO-EPSON (800-463-7766). Or you can purchase online at
www.epsonstore.com (U.S. sales) or www.epson.ca (Canadian sales).
Connecting Document Cameras
Document cameras have several different types of ports for connecting to the projector.
For cameras that have USB ports, such as the Epson DC-11 and Epson DC-06, the best way to connect is
directly to the computer's USB port, as shown below. This will enable full interactivity and dual pen support
(using Easy Interactive Tools software) on the document camera image.
Although you can connect the Epson DC-06 directly to the projector's TypeA port using a USB cable, this will
provide only limited interactivity (using the built-in interactive toolbar).
For document cameras that do not have a USB port, you can connect to the projector's VGA (Computer2) or
HDMI port. This will allow use of the projector's built-in interactive toolbar on the camera image.
If the document camera has USB and VGA connectors, you can connect a USB cable from the camera to the
computer and a VGA cable directly to the projector. This will provide two ways of connecting. The USB
