6. Installation and Connections
Cautions when connecting an HDMI cable
•	 Use	a	certified	High	Speed	HDMI®	Cable	or	High	Speed	HDMI®	Cable	with	Ethernet.
Cautions when connecting a DisplayPort cable
•	 Use	a	certified	DisplayPort	cable.
 
•	 Depending	on	the	computer,	some	time	may	be	required	until	the	image	is	displayed.
•	 Some	DisplayPort	cables	(commercially	available)	have	locks.
•	 To	disconnect	the	cable,	press	the	button	on	the	top	of	the	cable’s	connector,	then	pull	the	cable	out.
•	 No	power	is	supplied	from	the	DisplayPort	input	connector	to	the	connected	device.
•	 When	signals	from	a	device	 that	uses	 a	signal	 converter	 adapter	are	connected	 to	the	 DisplayPort	 input	connector,	
in	some	cases	the	image	may	not	be	displayed.
•	 When 	the 	HDMI 	output 	of 	a 	computer 	is 	connected 	to 	the 	DisplayPort 	input 	connector, 	use	a 	converter 	(commercially	
available).
Cautions	when	using	a	DVI	signal
•	 When	 the	computer	 has	a	DVI	 output	 connector,	 use	a	commercially	 available	converter	 cable	to	connect	 the	
computer	to	the	projector’s	HDMI	input	connector	(only	digital	video	signals	can	be	input). 	
	 To	connect	 the	computer’s	 DVI	output	 connector	 to	the	 projector’s	 DisplayPort	 input	connector,	 use	a	commercially	
available	converter.
HDMI IN
NOTE:	When	Viewing	a	DVI	Digital	Signal
•	 Use	 a	DVI-to-HDMI	 cable	compliant	 with	DDWG	 (Digital	 Display	 Working	 Group)	DVI	(Digital	 Visual	Interface)	 revision	1.0	stan-
dard.	The	cable	should	be	within	197"/5	m	long.
•	 Turn	off	the	projector	and	the	PC	before	connecting	the	DVI-to-HDMI	cable.
•	 To	project	a	DVI	digital	signal:	Connect	the	cables,	turn	the	projector	on,	then	select	the	HDMI	input.	Finally,	turn	on	your	PC.
	 Failure	 to	do	 so	may	 not	activate	 the	digital	 output	 of	the	 graphics	 card	resulting	 in	no	 picture	 being	displayed.	 Should	this	happen,	
restart	your	PC.
•	 Some	 graphics	 cards	have	both	analog	 RGB	(15-pin	 D-Sub)	and	DVI	 (or	DFP)	 outputs.	 Use	of	the	 15-pin	 D-Sub	connector	 may	
result in no picture being displayed from the digital output of the grap\
hics card.
•	 Do	not	disconnect	 the	DVI-to-HDMI	 cable	while	 the	projector	 is	running.	 If	the	 signal	 cable	has	been	 disconnected	 and	then	
reconnected,	an	image	may	not	be	correctly	displayed.	Should	this	happen,	restart	your	PC.

6. Installation and Connections
Connecting to a Wireless LAN (sold separately)
The	separately	 sold	wireless	 LAN	unit	allows	 you	to	use	 a	wireless	 LAN	environment. 	When	 using	the	projector	 in	a	
wireless	LAN	environment,	the	IP	address	and	other	settings	must	be	made	on	the	projector.
Important:
•	 If	 you	use	 the	projector	 with	the	USB	 Wireless	 LAN	Unit	in	the	 area	 where	 the	use	 of	wireless	 LAN	equipment	 is	
prohibited,	remove	the	USB	 Wireless	LAN	Unit	from	the	projector.
•	 Buy	the	appropriate	USB	 Wireless	LAN	Unit	for	your	country	or	area.
NOTE: 
•	 The	green	LED	on	the	USB	Wireless	LAN	Unit	flashes	to	show	that	the	USB	Wireless	LAN	Unit	is	working.
•	 Your	computer’s	wireless	LAN	adapter	(or	unit)	must	be	complied	with	Wi-Fi	(IEEE802.11b/g/n)	standard.
Flow of Setting Wireless LAN
Step	1:	 Attach	the	USB	Wireless	LAN	Unit	to	the	projector. 	(→	page	165)
Step	2:	 Display	[NETWORK	SETTINGS]	from	[APPLICATION	MENU]. 	(→	page	133)
Step	3:	 Select	[NETWORK	 SETTINGS]	→	[WIRELESS	 LAN]	→	[PROFILES]	 and	set	[EASY	 CONNECTION], 	
[PROFILE	1],	or	[PROFILE	2]. 	(→	page	134)
TIP:
Access	 the	HTTP	 server	 function	 to	set	 [NETWORK	 SETTINGS]	→	[SETTINGS]	→	[WIRELESS]	→	[EASY	 CONNECTION]	 ,	[PRO-
FILE1],	[PROFILE2].
Mounting a wireless LAN unit
NOTE:
•	
The	 wireless	 LAN	unit	has	a	front	 and	a	back	 and	must	 be	mounted	 in	the	 wireless	 LAN	port	in	a	specific	 direction.	 The	port	 is	
designed so that the unit cannot be mounted in the opposite direction, but trying to push it in by force could damage the wireless 
LAN	unit	port.
•	 To	 prevent	 damage	 due	to	static	 electricity,	 touch	a	nearby	 metal	object	 (a	door	 knob,	 aluminum	 sash,	etc.)	before	 touching	 the	
wireless	LAN	unit	to	eliminate	the	static	electricity	from	your	body.
•	 Turn	off	the	main	power	before	mounting	and	removing	the	wireless	LAN	unit.
	 Mounting	 and	removing	 the	wireless	 LAN	unit	while	 the	projector’s	 power	is	on	 could	 damage	 the	wireless	 LAN	unit	or	result	 in	
malfunction	 on	the	 projector.	 If	the	 projector	 should	malfunction,	 turn	off	the	 projector’s	 power,	turn	off	the	 main	 power	 switch,	
and unplug the power cord, then plug the power cord back in. 
•	 Do	not	connect	 any	USB	 device	 other	than	the	wireless	 LAN	unit	to	the	 USB	 (LAN)	 port.	Also,	 do	not	 connect	 the	wireless	 LAN	
unit	to	the	USB	port	in	the	connector	section.
