Preparation/SetUp
Preparation before using the network function
This projector is equipped with the network function to control and monitor the projector’s operations using a Web
browser and to send e-mail notification.
Before using the network function, perform the following three preparation steps.
(1) Setup of the application software “Projector-Control Device Installer”
(2) Setting of the IP address of the projector *1
(3) Setting of password, display language, LAN control, and PJLink™ certification using telnet.
*1 When setting IP addresses for multiple projectors collectively or when setting an IP address for a ceiling-
mounted projector after installation, check and take a note of combination of the projectors and the hardware
addresses (MAC addresses) in advance. To check the hardware addresses (MAC addresses), perform step 2
on the page 5.
