Link 21L

Select

 On 

to enable the projector to be monitored and controlled 

from a computer using Link 21L software and the Epson USB 
Communication driver.

■

Language 

Select a language to use for the projector menus.

To prevent unauthorized use of the projector, you can:

■

Assign a password. You can use the password to prevent the 
projector from being turned on and prevent your custom startup 
screen from being changed. See the next section.

■

Create a custom screen that is displayed at startup and/or when 
the 

A/V Mute

 button is pressed. The screen can be locked with a 

password to discourage theft and provides a way to identify the 
projector should it be stolen. See page 75. 

■

Disable the projector’s buttons; this is useful, for example, in a 
classroom when you want to ensure that no one touches the 
projector’s buttons while you’re using the remote control. See 
page 76.

■

Secure the projector to prevent theft using a cable locking system. 
See page 77.
