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 / Network
command table.
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 fulfills the specification
shown in figure
3.
Turn the computer on, and after the computer has started up turn the projector
on.
4.
Set the COMMUNICATION TYPE to OFF.
