Using the Interactive Features over a Network
124
You can use your projector in computer interactive mode over a network.
If you want to annotate when using computer interactive mode over a
network, you need to use Easy Interactive Tools (or another annotation
program). Easy Interactive Tools allows you to use various drawing tools,
treat the drawing area as a page, and save your drawings as a file for a later
use. You can download the software from the Epson website.
Use Epson iProjection (Windows/Mac) to setup your projector on a computer
network and use computer interactive mode over the network.
Select Use Interactive Pen on the General settings tab and Transfer layered
window on the Adjust performance tab.
See the Epson iProjection Operation Guide (Windows/Mac) for instructions.

• Number of pens or fingers you can use at the same time is as follows:
• Windows: two pens and six fingers
• Mac: one pen or one finger
• The response may be slower over the network.
• You can connect up to four projectors at one time using Epson
iProjection. When connected to multiple projectors, computer
interactive mode functions for any projector. Operations performed
on one projector are reflected in other projectors.

Precautions when Connecting to a Projector on a
Different Subnet
Follow these precautions when you connect to a projector on a different
subnet using Epson iProjection (Windows/Mac) and use interactive features:
• Search for the projector on the network by specifying the projector's IP
address. You cannot search for it by specifying the projector name.
• Make sure that you get an echo reply back from the network projector when
sending an echo request by the ping command. When the Internet Control
Message Protocol (ICMP) option is disabled on the router, you can connect
to the projector at remote locations even if you cannot get the echo reply
back.
• Make sure the following ports are opened.
Port Protocol Usage Communication
3620 TCP/UDP For connection and
control
two-way
3621 TCP For transferring images two-way
3629 TCP For controlling projector two-way
• Make sure that the MAC address filtering and application filtering options
are configured properly on the router.
• When bandwidth management is applied for communications between
locations, and Epson iProjection goes over the controlled bandwidth, you
may not be able to connect to the projector at remote locations.

Epson does not guarantee the connection to the projector on a
different subnet using Epson iProjection even if you meet the above
requirements. When considering the implementation, be sure to test
the connection in your network environment.
