The correct vertical and horizontal position of the projector in relation to the screen depends on 
the lens type and the screen size. Ideally, the projector should be positioned perpendicular to the 
screen. This way, the image will appear rectangular instead of keystoned (trapezoidal)\
. 
The  vertical position of the image can be offset – that is moved above or below the optical axis 
(lens center) by adjusting the fully motorized lens mount with the keypad. The amount of vertical 
offset available depends directly on the lens installed in the projector and can be slightly limited 
if horizontal offset has been applied. Vertical offset can also be expressed as the percent of half 
the image height OR the number of pixels of shift from lens center. Refer to Figure 2.1 for some 
illustrated examples of vertical offset. 
Table 2.1 along with Figure 2.2 show the maximum vertical offset of a lens or alternatively, how 
much  of  your  projected  image  will  appear  above  or  below  lens  center  if  the  maximum  vertical 
offset is applied using that lens.

The  horizontal  position  of  the  image  can  be  offset  –  that  is  moved  to  the  left  or  right  of  lens 
center, by adjusting the fully motorized lens mount through software. The amount of horizontal 
offset available depends on the lens installed and if the image has already been vertically offset. 
Horizontal  offset  can  also  be  expressed  as  the  percent  of  half  the  image  width  –  the  number 
of pixels of shift to one side of lens center. Refer to Figure 2.3 for some illustrated examples of 
horizontal offset.
See also Table 2.1 along with Figure 2.4 which shows the maximum horizontal offset of a lens 
or  alternatively,  how  much  of  your  projected  image  will  appear  to  one  side  of  lens  center  if  the 
maximum horizontal offset is applied using that lens.

MoUnTIng
There  are  several  methods  for  mounting  the  projector.  Depending  on  your  chosen  installation, 
one method may be more suitable than another. In typical front and rear screen installations the 
projector can be mounted to a secure and level surface, such as a table.\
CeIlIng MoUnT — The projector can also be inverted and suspended from the ceiling using 
a	 specially	 designed	 ceiling	mount	fixture.	 This	type	 of	mounting	 is	recommended	 for	fixed	
installations and for those that want the projector out of sight or have a limited space for projector 
and audience.
  Use only the Wolf CIneMa  approved ceiling mount kit designed for your projector. 
Refer to the installation instructions and safety guidelines provided in\
 the kit.
sPeCIal   MoUnTIng  —  The  projector  can  be  rotated  (front-to-back)  up  to  360  degrees  and 
mounted without it affecting performance. However, the side-to-side tilt limit of the projector must 
not  exceed  ±15  degrees.  This  tilt  limit  is  required  to  ensure  optimal  performance  of  the  lamp. 
(Figure 2.5.)
aDjUsTIng PRojeCT oR heIghT
You  can  modify  the  height  of  the  projector  to  remedy  a  slightly  unlevel  mounting  surface  by 
adjusting  the  two  feet  threaded  into  the  front  bottom  chassis.  Turn  each  foot  clock-wise  or 
counterclockwise until the project is level on all sides.
folDeD oPTICs
In  rear  screen  applications  where  space  behind  the  projector  is  limited,  a  mirror  may  be  used 
to  fold  the  optical  path.  The  position  of  the  projector  and  mirror  must  be  accurately  set  — if 
considering this type of installation call your dealer for assistance.

Sources connect to the Input Panel located at the back of the projector. See Figure 2.6.
The upper right corner (INPUT 1) typically accepts an RGB signal from an external analog RGB 
source, or it can also be used for YPbPr signals or additional video sources. Just beside these 
BNCs, the DVI-I connector  (INPUT 2) accepts digital or analog display signals from a computer. 
Connect analog composite video at  INPUT 3 or S-Video at INPUT 4 from devices such as VCRs, 
laser disc players or DVD players.
There  are  also  several  optional  interfaces  available  for  connecting  other  sources  —  these 
interfaces  slide  into  the  remaining  unused  option  slot,  and  can  be  done  while  the  projector  is 
running.
Figure 2.6 Input Panel
noTes: 1) See  Section 6, Specifications for details regarding compatible inputs.  2) Use high 
quality shielded cables only for all connections.
InPUT  1	 consists	of	five	 BNCs	 (connectors)	 for	linking	 to	a	variety	 of	sources.	 The	typical	
connection would be to an RGB source such as a PC, Mac. This projector supports multiple sync 
types with RGB signals: sync-on-green, composite sync, and separate H & \
V syncs.
noTe: Depending on your source, you may need a custom adapter cable with BNC connectors 
at the projector end and a different type of connector at the other (such as a 15-pin "D" connector 
for some computer sources). Contact your dealer for details.
Connect the  sYnC	BNC	input(s)	 first.	Then	 connect	 the	red,	 green	 and	blue	 source	 outputs	 to	
the  ReD,  gReen,  and  blUe  BNCs  on  the  InPUT  1  panel.  If  the  source  uses  sync-on-green, 
only  the  red,  green,  and  blue  connections  are  required.  If  the  source  provides  a  composite 
sync output, connect it to the  sYnC input labeled hoR/CoMP. If the source provides separate 
horizontal  and  vertical  sync  outputs,  connect  horizontal  sync  to  the  sYnC  input  labeled hoR/
CoMP and connect vertical sync to sYnC input labeled  VeRT. See Figure 2.7.

noTes: 1) If for some reason the projector fails to recognize a signal as an RGB signal, specify 
this Color Space option within the Picture Adjustments menu. See 3.5 Adjusting the Image.  2) To 
connect YPbPr signals–such as from DVDs or analog HDTV sources–to INPUT 1, use the red, 
green and blue BNCs as described in YPbPr Signals (below).
Connect a YPbPr signal (component video) to  InPUT 1 or InPUT 2 as shown in Figure 2.8.
noTes: 1) If, for some reason, the projector fails to recognize a YPbPr signal, specify this Color 
Space  option  within  the  Picture  Adjustments  menu.  See  3.5,  Adjusting  the  Image.  2)  Do  not 
connect digital component signals (known as YCbCr) to INPUT 1. Install an appropriate optional 
module in INPUT 5 or INPUT 6 for this.

DVI Digital Video
InPUT  3  and InPUT  4  provide  simultaneous  connection  of  both  a  composite  video  source 
(InPUT 3) and an S-Video source ( InPUT 4). See Figure 2.9. 
Use  the  DVI-I  connector  at  InPUT  2  to  connect  either  analog  or  digital  video  devices  to  the 
projector. When connecting devices that transmit an analog video signal such as VCRs, laptops, 
and PCs use the DVI cable provided with the projector. Plug the   DVI-I (single link) connector 
end to the projector and the 15-pin VGA connector to the device. 
Use  a  cable  with  DVI-I  connectors  at  both  ends  to  connect  devices  that  transmit  digital  and 
analog video signals such as high-quality DVD players, satellite receive\
r and digital cable TVs.
noTes:  1)  To  ensure  true  digital  output  from  devices  that  transmit  digital  signals,  connect  to 
the DVI-I connector. 2) DVI loop through is not available unless you have the optional DVI Input 
Module installed at INPUT 5 or INPUT 6.
Optional modules allow you to increase your total number of inputs and/or accommodate different 
signal types, whether analog or digital. Install in the areas labeled  InPUT 5 or InPUT 6. Options 
include:
Serial Digital Input Module - HD (SDI)
•	
DVI Input Module 
•	 (standard on XXXX HD models)
Dual SD/HD-SDI Module 
•	 (standard on XXXX HD models)

As  an  alternative  to  the  projector’s  keypad  or  remote,  you  may  wish  to  communicate  with  the 
projector using a PC or other controller. Such a device sends commands and receives feedback 
via  serial  links  (RS232  and  RS422),  Ethernet  or  GPIO  communications  to  the  projector,  all 
described below.
As desired, direct the projector’s IR remote keypad towards the display screen or the projector’s 
IR  sensors. Alternatively,  connect  a  wired  (tethered)  version  of  the  remote  to  the  3.5mm  mini-
stereo  jack  labeled  as ReMoTe  on  the  projector’s  input  panel.  Note  that  response  to  a  Wired 
Keypad  must  also  be  enabled  in  the  Communications  menu  —  see  3.6,  Adjusting  System 
Parameters and Advanced Controls for more information.
There are two types of serial ports available on the projector: RS232 and RS422. You can connect 
a device with a serial interface, such as a computer to either of these connectors (not both) and 
control	the	projector	remotely	by	entering	specific	serial	communication	commands.
ConneCTIng Rs-232
The  two  nine-pin  DIN  connectors  labeled  RS232  IN  and  RS232  OUT  on  the  input  panel  are 
dedicated to serial communication (see Figure 2.10). Using the appropriate serial communication 
cables  (see  Appendix  B)  connect  the  controlling  source,  such  as  a  personal  computer  to  the 
RS232 IN connector. Then set the baud rate to match that of the computer. Refer to  Section 3 
for details on changing the projector’s baud rate.
