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.

Command Control via the Network
When the projector connects network, the projector can be controlled with RS-
232C commands from the computer with web browser. 
For details of RS-232C commands, refer to RS-232C Communication / Network 
command table 
(19).
Connection
1. Turn off the projector and the computer.
2. Connect the projector's LAN port and the computer's LAN port with a LAN 
cable. Use the cable that fulfi lls the specifi cation shown in fi gure (Use CAT-5 
or greater LAN Cable when...

This projector is equipped with NETWORK BRIDGE function.
When the projector connects to the computer by LAN communicaton, an external 
device that is connected with this projector by RS-232C communication can be 
controlled from the computer as a network terminal.
For details, see the 3.7 Controlling the external device via the projector(using 
the NETWORK BRIDGE function) - Network Guide.
Connection
