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.)

● Connect to a desktop computer
● Connections for external control from the computer

- 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.

- 17 -
1. Select “ Baud rate ” and “ parity ” and input the projector control
code. (The baud rate, parity and control code is supplied by projector's
manufacturer, please refer to the projector’ manual)
2. The input format of projector's control code is as follows:
a. If the data is in the numerical value format, please input data directly, block them
off with comma, do not distinguish lowercase and uppercase.
For example: the “ POWER ON ” code in Hitachi projector manual is :
BE·EF·03·0
6·00
BA·0
2
01·0
0
00·6
0
01·0
0
In the POWRE ON box,Input : be, ef, 03, 06, 00, ba, d2, 01, 00, 00, 60, 01, 00. Then use
the same input rule to input other code.
b. If the data is in the character string format, input ‘character string’.
For example: the “ POWER ON ” code in the SHARP C40/50 projector manual
is :
P O W E - - - 1
（ “---- ” is space， is enter.）
In the POWER ON box, input ’POWR 1’, 0d, 0a
Input other codes in the same way.
c. If the data is in the numerical value and character format, then synthesize the

（Please disconnect the computer from the RS232 port first）. Then use buttons on the
operation panel to control the projector.
The visualizer provides a 6-pin to 9-pin RS232 cable. If this cable does not match to
your projector's RS232 port, an additional RS232 cable is needed. This additional RS232
cable can be made based on the pin location of the projector's RS232 control port. The
pin locations of the visualizer are: the pin 1 is RXD (Received Data); the pin 5 is TXD
(Transmitted Data); the pin 4 is GND (Ground). Other pins are not defined. The pin location
information of the projector is provided by the projector's manufacturer. The projector's
RS232 control port normally has RXD pin, TXD pin and GND pin, the name may be different.
The parallelism of each data pin is shown as follows:
Visualizer's RXD pin ----------------------- Projector's TXD pin
Visualizer's TXD pin ----------------------- Projector's RXD pin
Visualizer's GND pin ---------------------- Projector's GND pin
5. If you can not use buttons on the operation panel to control the projector, please use
Code- Writing software's projector control code testing function to check if the control
code is correct.
Click “ Projector ” button, the following dialog box appears as below:
Connect the visualizer to a computer with a RS232 cable (Please disconnect the projector
from the RS232 port first) and select the Baud Rate and Parity based on the projector's
