Connection to the ports (continued)
To input component video signal to COMPUTER IN ports
  ex.
To input component video signal to the COMPUTER IN1 or IN2 port of the 
projector, use a RCA to D-sub cable or adapter. 
For about the pin description of the required cable or adapter, refer to the 
descriptions about COMPUTER IN1 and IN2 port (

RS-232C Communication
RS-232C Communication
When the projector connects to the computer by RS-232C communication, the 
projector can be controlled with RS-232C commands from the computer. 
For details of RS-232C commands, refer to RS-232C Communication command 
table (
9).
Connection
1. 
Turn off the projector and the computer.
2. 
Connect the projector's CONTROL port and the computer's RS-232C port 
with a RS-232C cable (cross). Use the cable that fulfi lls the specifi cation 
shown in fi gure...

RS-232C Communication (continued)
NOTE • Operation cannot be guaranteed when the projector receives an 
undefined command or data.
• Provide an interval of at least 40ms between the response code and any 
other code.
• The projector outputs test data when the power supply is switched ON, and 
when the lamp is lit. Ignore this data.
• Commands are not accepted during warm-up.
