Controlling the Projector by a Computer

When the RS-232C terminal on the projector is connected to a computer with an RS-232C serial
control cable (cross type, commercially available), the computer can be used to control the
projector and check the status of the projector. Refer to the "SETUP MANUAL" contained on the
supplied CD-ROM for "RS-232C Specifications and Commands".
