FUNCTION
Using Serial Communication
If the projector is connected to a PC through an RS-232C cable, you can
use the PC to control functions of the projector such as power On/Off or
input selection, etc.
It cannot be used with the eZ-Net Manager concurrently. For serial commu-
nication, 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 need to 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).
