Operation
Power LED: Indicates if the RGB 116 p is receiving power.
Horizontal Center Control: The H Center Control [ ] shifts the
displayed image left or right.
Universal Input: Using E XTRON ’ S MBC input cables allows viewing on
both the computer monitor and large-screen projector/monitor at
the same time.
Termination Switch: 75 ohm video termination for applications with
no local monitor (Sw7, below).
RGB 116 p p p p p with Laptops
When using the RGB 116 p with laptops (or computers without
monitors) a termination adapter must be used to simulate a
monitor. If not, the computer/laptop may not boot up or may
default to an undesired lower resolution. Extron has termination
adapters for VGA, MAC, SUN and SGI. 75 ohm video termination
is selectable via DIP switch control.

Installation and Operation
Description
The RGB 116 p has a Video Bandwidth of 150 MHz and is
compatible with any Analog computer system with a horizontal
frequency range of 15-100 kHz (optimum 15-62 kHz). Using
Extron MBC Cables, the RGB 116
p is compatible with VGA, Super
VGA, IBM PS/2, MAC, MAC Quadra, XGA, XGA-2, DEC and
many others. Call Extron or refer to Extron’
S Handbook of
Computer Interfacing for a complete listing.
Installation (See illustration)
1. Turn off computer and its Monitor.
2. Disconnect the local Monitor cable from the computer and connect
it to the MBC cable.
3. Connect MBC display output cable to “Analog/ECL” on the
RGB 116 p .
4. Connect the MBC’s CPU cable to the
computer’s video output.
5. Apply power to the RGB 116 p , the CPU and
monitor.
Automatic Sync Output— The RGB 116 p will
automatically strip incoming Sync from the
R, G & B video channels. Sync will output
one of three ways, depending on the output
termination.
• 75 ohms on only R, G, & B channels, output is
sync on Green.
• 75 ohms on only R, G, B, & H/HV channels,
output is composite sync.
• 75 ohms on R, G, B, H/HV & V channels, output
is separate H & V sync.
