Making Connections
● Connect to the projector
Connect the PROJECTOR port to the projector's RGB IN port using the RGB cable.
You can also control a projector using the controls on the visualizer by connecting the
projector to the visualizer using a RS232 cable. Some projector models may require
a converter cable in addition to this standard RS232 cable to connect to the projector
control port, for the pin locations and shape of some projectors’ control port
connector may be different from the connector of a standard RS232 cable. Once the
visualizer
is connected to the projector, you can control the projector's power on, standby and
input selection by using the visualizer. (Aside from Hitachi projectors, the Code
Writing program that comes with the visualizer is required to access this function.)

- 8 -
Use the computer RS232 cable to make the connections displayed below to control
the visualizer from an external computer.
A USB connection enables the computer to capture still images and/or video
streams from the visualizer. Special software is required for this operation.
● Connect power source
First connect the power cord to the 12V IN connector.
