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...

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 or cart. Carts are useful when the projector has to be moved during a 
presentation or from site to site. It is recommended you lock the wheels on a cart, 
when it’s...

Sources connect to the Input Panel located at the back of the projector. See Figure 2.7. 
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...

Figure 2.8. Connecting RGB and Sync  
NOTES: 1) If for some reason the projector fails to recognize a signal as an RGB 
signal, specify this Color Space option within the Image Settings 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...

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 2.10.  
 
Figure 2.10.Connecting Composite or S-Video sources 
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...

 User’s Manual     2-15. 
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...

Connecting RS-422 
If you wish to control the projector with a computer and or other controlling device 
with RS-422 capability, connect a RS-422 serial communication cable between the 
computer and the RS-422 port on the projector. RS-422 is better suited for serial 
communication over long distances then is RS-232 communication.  
 Use the RS-422 port only if your device had RS-422 capability – always consult...
