A physical connection route for a source signal, described by a two-digit number 
representing 1) its switcher/projector location and 2) its slot in the switcher/projector. 
Signal sent from a source device to the projector. 
A device, such as the Serial Digital Input Module, that accepts an input signal for 
display by the projector.

 Appendix A: Glossary 
020-100001-01 Rev. 01 (04/07) A-5 
A list of selectable options displayed on the screen. 
A video output format of some video tape and disk players. There are two types of 
NTSC (National Television Standards Committee) video: NTSC 3.58 and NTSC 4.43. 
NTSC 3.58 is used primarily in North America and Japan. NTSC 4.43 is less 
commonly used. 
A type of rear-projection screen which re-directs light through the screen to increase 
image brightness in front of the screen. Screen gain...

Appendix A: Glossary  
A-6 020-100001-01 Rev. 01 (04/07) 
The minimum time required for a CRT projector to move the position of the scanning 
spot from the right edge to the left edge. 
The time required by the video amplifier of the projector to increase its output from 
10% to 90% of the maximum value. 
The video output (analog or digital) of most computers. Analog RGB video can have 
three, four, or five wires — one each for red, green, and blue, and either none, one or 
two for sync. For three-wire...

 Appendix A: Glossary

The duration of each sync pulse generated by a computer. The sync width is part of 
the blanking time. 
A type of RGB video with digital characteristics. 
A wire connecting a single video source to a display device, such as a projector, must 
be terminated by a resistance (usually 75Σ for video). 
The distance between the front feet of the projector and the screen. Also called 
“Projector-to-Screen Distance”. Always use the correct Christie throw...

Appendix B 
Keypad Reference 
 
020-100001-01 Rev. 01 (04/07)  B-1 
NOTE: The IR remote is a standard component provided with the projector. Use the 
extension cable also provided to convert the IR remote to a wired remote, if desired.  
Refer to Section 3 for a specific description of each key and how to use them 
correctly. 
 
* Toggle keys, which require you to either, press and hold, or press twice or press and 
use the up/down arrow key.  

Appendix C 
Serial Communication 
Cables 
 
020-100001-01 Rev. 01 (04/07) C-1 
A serial link of RS232 or RS422 enables ASCII communication with the projector so 
that it can be controlled remotely from a PC or other controller. From a PC, connect a 
standard nine-wire RS232 serial cable to the 
RS232 IN port. Or, for long-distance 
(>100 ft.) links with an RS422-compatible PC or controller, connect RS422 cable to 
the 
RS422 port. 
 
 
 
  

Appendix D 
Throw Distance 
 
020-100001-01 Rev. 01 (04/07) D-1 
Calculating Throw Distance 
It is important throw distance be 
precisely calculated for your 
installation using the appropriate 
formula from the chart below. To 
calculate throw distance you must 
know the screen size and the lens 
type installed in the projector. In 
general, the larger you want the 
image to be the greater the distance 
you must allow between the lens and 
the screen. 
NOTES: 1) Throw distance is measured from the...
