Compatibility
INPUT
The IN3260 Installation Distribution Amplifier operates with analog video input from a wide
variety of IBM and compatible computer video signal formats including VGA, SVGA and XGA.
OUTPUT GAIN
To set the output gain for the main or local monitor outputs, close the appropriate jumpers
according to the table below. Be sure that the Red, Green and Blue output jumpers for each output
are all set to the same setting. The factory default setting for both outputs is unity gain.
Output Gain Jumper Settings for Output 1 (15-pin HD Local Monitor Output)
Gain 1.0
(Unity)
Gain 1.2
(20% Signal Boost)
Gain 1.4
(40% Signal Boost)
Red 9 8 7
Green 13 12 11
Blue 16 15 14
Output Gain Jumper Settings for Output 2 (6 BNC Main Output)
Gain 1.0
(Unity)
Gain 1.2
(20% Signal Boost)
Gain 1.4
(40% Signal Boost)
Red 19 18 17
Green 22 21 20
Blue 25 24 23
MONITOR EMULATION
Setting the jumpers according to the table below will configure the unit for automatic or manual
emulation:
Emulation for 15-pin HD
Male Input Connector
Auto Emulation
(Factory Default)
Manual Emulation
(Pin Always Grounded)
Pin 11 JP1 Open JP1 Closed
Automatic Factory Emulation (Factory Default)
When the unit is operating in automatic emulation mode, emulation sense pins are treated in the
following manner:
•
Monitor Connected to Local Monitor Output - All sense pins are passed from the input
connector to the local monitor output connector, allowing the monitor to set the emulation
automatically.
•
No Monitor Connection to the Local Monitor Output - The distribution amplifier
emulates a VGA Color / MAC 13” RGB monitor automatically.
