6. Installation and Connections
Connecting to a Wired LAN (not supported by PE501X)
The	projector	comes	standard	with	a	LAN	port	(RJ-45)	which	provides	a	LAN	connection	using	a	LAN	cable.	
To	use	 a	LAN	 connection,	 you	are	required	 to	set	 the	 LAN	 on	the	 projector	 menu.	Select	 [SETUP]	→	[WIRED	 LAN].

6. Installation and Connections
Connecting to a Wireless LAN (Optional: NP02LM series) (not supported by PE501X)
The	USB	 Wireless	 LAN	Unit	also	 provides	 a	wireless	 LAN	connection. 	To	 use	 a	wireless	 LAN	connection,	 you	are	
required	to	assign	an	IP	address	to	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.
Step 2:	 Connect	the	computer	to	the	projector	via	wired	LAN. 	(→	page	151)
	 Use	the	computer’s	browser	to	display	the	projector’s	HTTP	server. 	(→	page	42)
Step 3:	 Use	an	HTTP	server	to	set	the	wireless	LAN.	(→	page	45)
	 Access	the	HTTP	 server	 function	 to	set	 [NETWORK	 SETTINGS]	→	[SETTINGS]	→	[WIRELESS]	→ 
[EASY	CONNECTION], 	[SIMPLE	ACCESS	POINT], 	[PROFILE1]	or	[PROFILE2].
NOTE:	
•	 To	use	the	HTTP	server	function,	the	projector	must	be	connected	to	a	network.
	 First	use	the	wired	LAN	to	connect	the	projector	to	a	network	and	then	use	the	HTTP	server	to	set	the	wireless	LAN.
•	 After	setting	the	wireless	LAN	by	using	the	HTTP	server,	set	[NETWORK	SETTINGS]	→	[SETTINGS]	→	[WIRED]	→	[DISABLE]
When	switching	to	set	on	the	projector	after	connecting	to	the	wireless	LAN:
Use	the	menu	to	set	the	wireless	LAN	connection	for	the	projector. 	
(→	page	120)
Select	[DISABLE],	 [EASY	CONNECTION],	 [SIMPLE	ACCESS	 POINT],	[PROFILE1]	 or	[PROFILE2]	 you	set	from	 the	
HTTP	server.
Attaching	the	USB	 Wireless	LAN	Unit
NOTE:
•	 The	USB	Wireless	 LAN	Unit	must	 be	inserted	 into	the	USB	 Wireless	 LAN	Unit	port	in	the	 correct	 direction.	 It	cannot	 be	inserted	
in	the	 reverse	 direction.	 If	the	 USB	 Wireless	 LAN	Unit	is	inserted	 in	the	 reverse	 direction	 with	excessive	 force	applied,	 the	USB	
port	may	break.
•	 Before	 touching	the 	USB 	Wireless 	LAN 	Unit,	 touch	 a	metallic 	object	 (such	as	a 	door 	knob 	or 	aluminum 	window	 frame)	to	discharge	
the	static	electricity	from	your	body.
•	 Always	 insert	or	remove	 the	USB	 Wireless	 LAN	unit	when	 the	main	 power	 is	turned	 off.	Failure	 to	do	 so	may	 cause	 projector	
malfunction	 or	damage	 to	the	 USB	 wireless	 LAN	unit.	 If	the	 projector	 will	not	work	 correctly,	 turn	off	the	 projector,	 disconnect	
the	power	cord,	and	then	connect	it	again.
•	 Do	not	insert	 other	USB	devices	 into	the	USB	 Wireless	 LAN	unit	port.	 Do	not	 insert	 the	USB	 Wireless	 LAN	unit	into	the	USB	 (PC)	
port	(Type	B).
•	 Although	the	PE501X	does	not	support	wireless	LAN,	a	wireless	mark	(		)	is	shown	on	the	cabinet.

cover.
To	 remove	 the	USB	 Wireless	 LAN	Unit,	 disconnect	 the	power	 cord	
and	use	the	above	procedure.
NOTE:	
•	 The	green	LED	on	the	 USB	 Wireless	 LAN	Unit	flashes	 to	show	 that	Wireless	
LAN	 Unit	is	working.	 If	the	 USB	 Wireless	 LAN	Unit	is	incorrectly	 attached,	
the	blue	LED	will	not	flash.

6. Installation and Connections
Attaching the Optional Cable Cover (NP03CV)
An	optional	cable	cover	(NP03CV)	is	available	for	hiding	cables.
The	NP03CV	cable	cover	is	designed	for	use	with	the	P	series	projectors.
 CAUTION:
•	 Be	sure	to	tighten	 the	screws	 after	attaching	 the	cable	 cover.	Failure	 to	do	 so	may	 cause	 the	cable	 cover	 to	come	
off	and	fall,	resulting	in	injury	or	damage	to	the	cable	cover.
•	 Do	not	put	bundled	cables	in	the	cable	cover. 	Failure	to	do	so	may	damage	the	power	cord,	resulting	a	fire.
Attaching	the	cable	cover
Attach	the	cable	cover	after	installing	the	projector	on	the	ceiling	and	connecting	cables.
Tool	needed	for	attaching:
•	 Phillips	screwdriver	(plus-head)
1.	 Align	two	tabs	on	the	outside	of	the	cable	cover	with	grooves	of	the	projector	and	push	the	top	end.
•	 At	the	same	 time	two	tabs	 on	the	 inside	 of	the	 cable	 cover	 will	be	engaged	 in	the	 responding	 grooves	of	the	
projector. 
NOTE:
•	 Be	careful	not	to	get	cables	caught	in	between	the	cable	cover	and	the	projector.
2.	 Tighten	the	cable	cover	screws.
•	 Be	sure	to	tighten	the	screws.

7. Maintenance
This	 section	 describes	 the	simple	 maintenance	 procedures	you	should	 follow	to	clean	 the	filters,	 the	lens,	 the	cabinet,	
and	to	replace	the	lamp	and	the	filters.
❶ Cleaning the Filters
The	 air-filter	 sponge	keeps	dust	and	dirt	from	 getting	 inside	the	projector	 and	should	 be	frequently	 cleaned.	If	 the	 filter	
is	dirty	or	clogged,	your	projector	may	overheat.
NOTE:	 The	message	 for	filter	 cleaning	 will	be	displayed	 for	one	 minute	 after	the	projector	 is	turned	 on	or	off.	 When	 the	message	 is	
displayed,	clean	the	filters.	The	time	to	clean	the	filters	is	set	to	[OFF]	at	time	of	shipment.
To	cancel	the	message,	press	any	button	on	the	projector	cabinet	or	the	remote	control.
The	two-layer	 filter	on	the	 projector	 improves	 cooling	and	dust-proof	 capabilities	 compared	with	the	conventional	
models.
The	outsides	(intake	side)	of	the	first	and	second	layer	filters	remove	dust.
To	clean	the	filter,	detach	the	filter	unit	and	the	filter	cover.
 CAUTION
•	 Before	 cleaning	the	filters,	 turn	off	the	 projector,	 disconnect	 the	power	 cord	and	then	 allow	 the	cabinet	 to	cool. 	
Failure	to	do	so	can	result	in	electric	shock	or	burn	injuries.

7. Maintenance
(2) Push  the  left  end  of  each  filter  and  remove  the  hard  two 
honeycomb filters (large and small).
	 •		 The	 large	 filter	cannot	 be	removed	 by	pushing	 on	its	right	
end.
4.	 Use	a	vacuum	cleaner	to	vacuum	all	the	dust	inside.
 Get rid of dust in the accordion filter
NOTE:	
•	 Whenever	 you	vacuum	 the	filter,	 use	the	soft	 brush	 attachment	 to	
vacuum.	This	is	to	avoid	damage	to	the	filter.
•	 Do	not	wash	 the	filter	 with	water.	 Doing	so	can	 result	 in	filter	 clog-
ging.
5.	 Remove	dust	from	the	filter	unit	and	the	filter	cover.
  Clean both outside and inside.
6.	 Attach	the	four	filters	to	the	filter	unit.
(1)	Insert	 the	left	end	 of	each	 hard	honeycomb	 filter	(large	 and	
small) first and then the right end of each hard honeycomb 
filter to the filter unit.
	 •		The	large	filter	cannot	be	fitted	if	its	right	end	is	inserted.
(2) Turn the filter unit over.
	 •		 Attach 	the 	two 	soft 	accordion 	filters 	(large 	and 	small). 	Each	
accordion filter has a slit on it. Align the slit with each pro -
trusion of the filter unit.Slit

7. Maintenance
7.	 Put	the	filter	unit	back	to	the	projector	cabinet.
	 Make	sure	that	the	filter	 unit	is	placed	 in	the	 correct	 orienta-
tion.
8.	 Put	the	filter	cover	back	to	the	projector	cabinet.
	 Insert	 two	catches	 of	the	 top	side	 of	the	 filter	 cover	 into	the	
groove of the cabinet, and push the buttons on the left and right 
to close the filter cover.
•	 Push	the	filter	cover	until	it	clicks	into	place.
9.	 Clear	the	filter	usage	hours.
 Plug the power cord into the wall outlet, and then turn on the 
projector.
 From the menu, select [RESET] →	[CLEAR	 FILTER	HOURS]. 	
(→ page 117)
 The interval time to clean the filters is set to [OFF] at time of 
shipment. When  using  the  projector  as  it  is,  you  do  not  clear 
the filter usage
