4a. MBC Power Connector If the Analog/ECL, MBC video

cable has a small, phono jack attached to it, plug it into
this female connector.

5. RS-232 Control (optional) -If using a PC, or other system to

program the RGB 300, connect the cable here. (pin-outs
and interface specifications are given under Installation
Check, after this procedure.)

6a. Turn Power ON for the Computer supplying the video

input. - (Power PC, PC, Mac or workstation)

6b. Turn Power ON for the Data Monitor/Projector.

6c. Connect power to the RGB 300.

7. Observe that the RGB 300 LCD display lights up, and cycles

through three default menus.

7a. The ID, or Title Menu - Displays the name of the unit.

To change this display, see the

Editing The ID Screen,

in Chapter 3.

7b. The Scan Rate Menu - From the monitor breakout cable,

the RGB 300 detects the scan rate frequencies and
displays them. This is an example.

7c. The Video Input Menu - If the RGB 300 has detected

Red, Green & Blue inputs, the first line displays the
letters RGB. The second line displays the Memory Block
# and video format that was loaded, either manually or
automatically. This is an example.

Installation Check

To be sure the installation is complete, do the following:

1. Check that the LCD default menus show the correct

information. (as described in Step 7, above). Use the menus
as a troubleshooting aide.

If, for example, green input is missing, the RGB display would
show the “G” missing. For this example, the second line

shows the RGB 300 is using settings stored in Memory
05, which is preset for a VESA2. Check to be sure the
correct block was loaded. (See Memory Block table.)

____ The memory block that is loaded automatically is the first

match the RGB 300 finds. If there is a specialized block with a
higher block number, it may not load automatically because the
scan for a match begins with block #1.

Before Installing the Extron RGB 300

____ Do not connect the power cord until instructed to do so in the

following installation procedure. There is no power switch.

For quick, automatic setup, use the following Basic
Installation steps. The RGB 300 will detect the scan rate
from the computer and automatically load a video format from
a preset memory block. For most applications, the installation
should be complete. The Front Panel may be used later for
custom installation, or to make changes after completion of
the basic installation.

Quick Setup Procedure (rear panel cables)

1. Turn Computer and Monitor Power OFF

Do not connect the RGB 300 Power Cable yet. (There is no
power switch.)

2. Disconnect the Local Computer Monitor Video Cable.

3. Connect BNC Output Cables to the Data Monitor/Projector -

All BNC outputs are RGB analog. The BNC connectors are
marked R, B, G, H/V and V. They may be connected any of
three ways:

• Red, Green/sync and Blue, for RGB with sync on green.

(3-cable hook up)

• Red, Green, Blue and H/HV, for RGB with composite

Horizontal and Vertical Sync signals. (4-cable hook up)

• Red, Green, Blue, H/HV and V, for RGB with separate

Horizontal and Vertical Sync signals. (5-cable hook up)

The Extron RGB 300 automatically detects which cables are
connected and sends sync signals to the correct output.

______ The output cables must have 75 W termination at the Data

Monitor/ Projector; if not, the automatic setup may not work.
Look for a switch on the Data Monitor.

4. Connect the MBC video cable from the computer (Power

PC, PC, Mac or workstation) to this Analog/ECL Input
connector, and to the Local Monitor.
