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.

Serial Communication 
Cables 
 
   Christie DS+60 User’s Manual    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 9-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.

Throw Distance 
 
   Christie DS+60 User’s Manual     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 the perpendicular distance from the screen to the place 
of the projector’s front feet. 2) This measurement is not necessarily parallel to the 
floor as the projector and screen may be inclined. 3) Due to lens manufacturing, 
throw distance calculations have a tolerance of 
± 5%.

Where:  
TD = projector distance from the screen to the center of the projector’s front feet. 
W = screen (image) width (cm)
