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/DW30/Matrix 3000 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 center 
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%.

System Integration 
 
   Christie DS+60/DW30/Matrix 3000 User’s Manual     E-1 
The GPIO connector located on the input panel provides a flexible method of interfacing a wide range 
of external I/O devices to the projector. There are 7 GIO pins available on the 9pin D-Sub GPIO 
connector, which are configurable via RS232 commands. The other two pins are reserved for ground 
and power – see table below for pin identification. 
 
GPIO Pins 
Pin #  Signal 
1  + 12V (200mA) 
2 GPIO 1 
3 GPIO 2 
4 GPIO 3 
5 Ground 
6 GPIO 4 
7 GPIO 5 
8 GPIO 6 
9 GPIO 7 
 
The serial cable required for connecting the external device to the projector’s GPIO connector, 
whether it’s a standard serial cable or a custom one, must be compatible with the external device.  
 Configuring the GPIO  
The GPIO connector can be configured to automate any number of events using the serial 
command code GIO. Each pin is defined as either an input or output depending on the 
desired outcome. In general, configure the pin as an input if you want the projector to respond 
to something the device does and as an output if you want the external device to respond to an 
action taken by the projector. For example, configure the pin as an output if you want the 
lighting in a room to automatically dim when the projector is turned on. 
By using the GIO command, you can also set the state of each pin as high or low. By default, 
the state of each pin is high. The voltage applied to pins in the high state is  + 3.3V. 
Example 1.
 Turn room lighting on when the projector is turned off. (Assumes a 
control/automation unit is configured to turn the lights on when pin 2 of it’s input goes high.) 
(GIO C2 O)   Set pin #2 configuration to output  
(GIO 2 H)  Set pin #2 to high (state)
