4. How to Set Up Extron System 5 IP Switcher Hardware

 

Video Output:

Both RGB (computer 1/2) and Y/C (s-video) connectors need to be attached in order for all of the devices to work properly.

Connect and lock (by twisting) the RGB connectors, as well as horizontal and vertical sync.

NOTE: If the cable is produced by Extron, the black wire is horizontal sync and yellow wire is vertical.  Having horizontal and vertical sync connected properly is very important, you may receive no single if switched.

The Y/C connectors are labled on the cables (usually Y22 and C22) and connect in the same fashion as the RGB.

 

Video Input:

Input 1 corresponds to PC output. A VGA/RGB cable is used to connect from the PC to the switcher.

Connect a second VGA/RGB cable from VGA out on the document camera to Input 2 on the switcher.

NOTE: RGB connectors not made by extron may be formatted differently.  In this case grey is horizontal sync and black is vertical.  Having horizontal and vertical sync connected properly is very important, you may receive no single if switched.

 

Audio IN/OUT & RS-232:

The RS-232 serial connection is what the switcher uses to communicate with the projector.  Problems switching between inputs and/or turning the projector unit on/off are related to either the RS-232 connection or improper programming.  Make sure the red, black, and white wires are correctly seated and connect as shown below. 

NOTE: RS-232 is usually labeled X1.

The audio inputs are located on the row below the rs-232 connection.  Each channel corresponds to the same number video channel.  As you can see, there is no audio connected to channel 2 as the document camera doesn't output audio.

NOTE: These cables are NOT labeled correctly.  In most cases the cable labeled L2R should go in channel 1; L2R in channel 3; and L4R in channel 4.

Finally, audio output or the preamp connection is the cable labeled L24R and connects between the audio mixer, amplifier, and switcher.

 

Now that all of the input and output connects have been made you can may plug the power cable in and move on to the next chapter on software setup.
