 Operating the Projector Via the LAN (Virtual Remote Tool)
Using	the	software	 program	“Virtual	Remote	 Tool”	that	 you	can	 download	 from	our	web	 site,	Virtual	 Remote	 screen	
(or	toolbar)	can	be	displayed	on	your	computer	screen.
This	will	help	 you	perform	 operations	 such	as	projector’s	 power	on	or	off	 and	 signal	 selection	 via	a	LAN	 connection. 	It	
is	 also	 used	 to	send	 an	image	 to	the	 projector	 and	register	 it	as	 the	 logo	 data	 of	the	 projector. 	After	 registering	 it,	you	
can	lock	the	logo	to	prevent	it	from	changing.
Control Functions
Power	 On/Off,	 signal	selection,	 picture	freeze,	 picture	mute,	Logo	transfer	 to	the	 projector,	 and	remote	 control	op-
eration	on	your	PC.
Virtual	Remote	screen
Remote	Control	 WindowToolbar
This	section	provides	an	outline	of	preparation	for	use	of	 Virtual	Remote	Tool.
For	information	on	how	to	use	 Virtual	Remote	Tool,	see	Help	of	 Virtual	Remote	Tool.	(→	page	201)
NOTE:
•	 Logo	data	(graphics)	that	can	be	sent	to	the	projector	with	Virtual	Remote	Tool	has	the	following	restrictions:
-	 File	size:	256	KB	or	less	
-	 Image	size	(resolution):	the	native	resolution	of	the projector
-	 File	format:	JPEG
•	 The	 logo	data	that	is	sent	 with	 Virtual	 Remote	 Tool	will	be	displayed	 at	the	 center	 of	the	 screen.	 Its	surrounding	 will	be	painted	
out in black.
•	 Once	 you	have	 changed	 the	background	 selection	from	the	default	 “NEC	logo”	 to	another	 selection,	 you	cannot	 return	the	logo	 to	
the	default	 “NEC	logo”	 even	after	using	 [RESET].	 To	put	 the	default	 “NEC	logo”	 back	in	the	 background	 logo,	you	need	 to	register	
it	as	 the	 background	 logo	by	using	 the	image	 file	(\Logo\NEC_logo_black_WUXGA.jpg)	 included	on	the	 supplied	 NEC	Projector	
CD-ROM.
TIP:
•	 Virtual	Remote	Tool	can	be	used	also	with	a	serial	connection.
•	 To	download	or	update	Virtual	Remote	Tool,	visit	our	website:	http://www.nec-display.com/dl/en/index.html
Connect the projector to a LAN.
Connect	 the	projector	 to	the	 LAN	 by	following	 the	instructions	 in	“Connecting	 to	a	Wired	 LAN”	(→	page	163),	 “Con-
necting	 to	a	Wireless	 LAN	(sold	 separately)” 	(→	page	164)	 and	 “9	Application	 Menus	-	NETWORK	 SETTINGS”	(→

 Throw distance and screen size
Six	separate	 bayonet	style	lenses	 can	be	used	 on	this	 projector. 	Refer	 to	the	 information	 on	this	 page	 and	use	a	lens	
suited	 for	the	 installation	 environment	 (screen	size	and	throw	 distance). 	For	 instructions	 on	mounting	 the	lens,	 see	
page	154.
Each	number	provided	in	the	table	below	means	the	throw	distance	between	the	lens	surface	and	the	screen.

TIP
Calculation	of	the	throw	distance	from	the	screen	size
NP16FL	lens	throw	distance	(m)	=	H	×	0.8	:	0.8	m	(min.)	to	5.1	m	(max.)	
NP17ZL	lens	throw	distance	(m)	=	H	×	1.3	to	H	×	1.8	:	1.3	m	(min.)	to	11.7	m	(max.)	
NP18ZL	lens	throw	distance	(m)	=	H	×	1.7	to	H	×	2.3	:	1.8	m	(min.)	to	14.9	m	(max.)	
NP19ZL	lens	throw	distance	(m)	=	H	×	2.2	to	H	×	3.7	:	2.4	m	(min.)	to	24.1	m	(max.)	
NP20ZL	lens	throw	distance	(m)	=	H	×	3.6	to	H	×	5.4	:	3.8	m	(min.)	to	35.4	m	(max.)	
NP21ZL	lens	throw	distance	(m)	=	H	×	5.3	to	H	×	8.3	:	5.6	m	(min.)	to	54.8	m	(max.)	
“H”	(Horizontal)	refers	to	the	screen	width.
*	Figures	differ	by	several	%	with	the	table	above	because	the	calculation 	is	approximate.
Ex.:	Throw	distance	when	projecting	on	a	150"	screen	using	the	NP18ZL	lens:
According	to	the	“Screen	Size	(for	reference)”	table	(→ page 206),	H	(screen	width)	=	323.1	cm.
The	throw	distance	is	323.1	cm	×	1.7	to	323.1	cm	×	2.3	=	549.3	cm	to	743.13	cm	(because	of	the	zoom	lens).
