Projector Christie Roadster S+20k User Manual

  Roadster/Mirage S+ User’s Manual 2-15 
Installation type, screen type, and lighting all affect where the projector is positioned. 
In addition, both throw distance (the distance between the projector and screen) and 
vertical position (the height of the projector in relation to the screen) must be 
determined for every new installation. Both depend on the screen size and lens type 
you are using. Make sure that the room can accommodate the required position of the 
projector for...

If necessary, vertical position of the image can be offset—that is, moved up or down 
in relation to lens center—by using the motorized offset function. Starting with no 
offset, the image from this projector can be moved up or down by a maximum 
distance of 525 pixels for SXGA+ resolution, resulting in the entire image displayed 
above or below lens center. See Table 2.1 and Figure 2.20.  
NOTE: Not applicable for the fixed lens.

NOTES: 1) If the image becomes keystoned or 
exhibits uneven brightness, the projector may 
simply be too high or low in relation to the 
screen. 2) Recommended offset ranges can be 
exceeded, however this may affect image 
quality. 3) Simultaneous horizontal and 
vertical offset limits the adjustment range of 
each. 4) Offset can vary by ±7% and may be 
affected by the degree of zoom currently in 
use.

In rear screen applications (Figure 2.23) 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. Consult your 
dealer or Christie for details. 
 
 
Sources connect to the Input Panel located on the rear of the projector. As shown in 
Figure 2.24, the upper right corner (
INPUT 1)  typically accepts an RGB signal from 
an external analog RGB...

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 2.25, below.

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 3.6, Adjusting the 
Image. 2) To connect...

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 2.27 below.

Christie’s Dual SD/HD-SDI input module is standard with the Roadster S+ and 
factory-installed in 
INPUT 5 or INPUT 6. The module’s loop-through capability 
enables incoming serial digital data to be tiled across multiple screens, creating vast...

NOTES: 1) Optional digital interfaces cannot be used in a Marquee Case/Power 
Supply.2) See Appendix F, Optional Input Modules for a brief description of each 
interface. 
 
The most common method of controlling the projector is via one of its keypads. As 
an alternative, you may wish to communicate using a PC or similar controller. Such a 
device sends commands and receives feedback via serial links (2 types), Ethernet or 
GPIO...

Figure 2.29. RS422 Connection to a Computer 
The nine-pin RS422 connector is located at the rear of the projector (Figure 2.29).  
Use this port for communications to and from an RS422-compatible controller. In the 
Communications menu, set the baud rate to match that of your RS422 controlling 
device. 
WARNING 
Do not use an RS422 port unless you are using 
equipment with RS422 capability. The voltage levels of 
this signal can damage...

Figure 2.30. Connecting Ethernet  
Upon connection to an Ethernet network, the projector’s factory default IP address of 
0.0.0.0 will automatically enable the DHCP function (if available on the network) to 
assign a new IP address that is valid and unique for that network. Or, if there is no 
DHCP function available on the network  (or if a specific static IP address for the 
projector is preferred or required), you can set the address in...

You may wish to chain two or more projectors together so that commands and 
communications to and from a controller are relayed to all projectors. Choose a 
hardware configuration that best suits your desired communication method. 
RS232 NETWORK: To control multiple projectors with a computer/controller having 
an RS232 interface, first set all projectors to the same baud rate as the controller, then 
chain the...
