Installation and Operation

Description

The Extron RGB 124 is a 200 MHz Dual Output, universal Analog/ECL computer-video
interface designed to connect workstations and PCs to a large screen display system.
With an Extron MBC (monitor breakout cable), the computer’s local monitor may be used
while the RGB/BNC output goes to a large screen. Analog or ECL inputs can be from
VGA, Mac, XGA, XGA-2, Quadra, SUN, SGI, Solbourne, NEC, Siemens, DEC or other
source.

Installation using an MBC cable

1. Use diagram to the right as a guide. Turn off
the computer and its monitor.

2. Disconnect the local Monitor cable from the
computer and connect it to the MBC cable(A).

3 Connect the MBC cable 9-pin connector to

"Analog/ECL" on the RGB 124 (B).

4. Connect the remaining MBC cable to the
computer's video output (C).

5. Connect RGB 124 Outputs 1 and 2 to output
devices (see Automatic Sync Output below).

6. Apply power to the RGB 124, the CPU and its
monitor, and the output devices.

Installation using an MBC buffer

1. Use diagram to the right as a guide. Turn off the
computer and its monitor.

2. Disconnect the local Monitor cable from the
computer and connect it to the MBC buffer
connector labeled "Local Monitor" (A).

3. Connect the MBC buffer cable 9-pin connector to
the "Analog/ECL" connector on the RGB 124 (B).
Connect the small plug on the same cable to
"MBC Power Output" on the RGB 124 (B1).

4. Connect the remaining MBC buffer cable to the
computer's video output.

5. Connect RGB 124 Outputs 1 and 2 to output
devices (see Automatic Sync Output below).

6. Apply power to the RGB 124, the CPU and its
monitor, and the output devices.
