Using Serial Communication
If the projector is connected to a PC through an RS-232C cable, you can use the PC to
control projector functions such as power On/Off and input selection.
It cannot be used with the eZ-Net Manager
concurrently. For serial communication, set
LAN to Off in the eZ-Net Manager.
This function may not be available for a particular menu or input mode.
Establishing Serial Communication
Connect the RS-232C (serial connector) of the PC to the RS-232C connector at the back
of the projector.
You must purchase a cable to connect the RS-232C connectors, as it is not provided as an
accessory.
* A RS-232C cable is necessary for the remote control of the projector (see Figure 1).
