Defi nitions
The following terms, which apply to all Extron matrix switchers, are used
throughout this manual:
Tie
—
An input-to-output connection.
Set of ties —
An input
tied
to two or more outputs. (An output can never be tied
to more than one input.)
Confi guration —
One or more
ties
or one or more
sets of ties
.
Current
confi guration —
The
confi guration
that is currently active in the
switcher (also called
confi guration 0
)
Global memory preset —
A
confi guration
that has been stored. Up to 32
global
memory presets
can be stored in memory. Preset locations are assigned to
the input buttons and (where necessary) output buttons. Up to 26 presets can
be selected from the front panel for either saving or retrieving. When a
preset
is retrieved from memory, it becomes the
current confi guration
. The switcher
has 32 presets; preset numbers larger than 26 are still accessible under RS-232
control.
Features
Video —
Computer video group —
The switcher inputs and outputs RGBHV (VGA),
RGBS, RGsB, RsGsBs, or Y, R-Y, B-Y video on 15-pin HD connectors.
Low resolution video group —
The switcher inputs and outputs NTSC 3.58,
NTSC 4.43, PAL, or SECAM S-video and/or composite video on BNC
connectors.
•
Inputs 9 and 10
(the fi rst two low resolution video group video inputs) are
composite video only.
•
Input 9
is a genlock reference. All other low resolution inputs are synced to
input 9.
•
Inputs 11 through 14
(the remaining low resolution video group video
inputs) can accept either S-video or composite video.
•
Outputs 7 and 8
(the fi rst two low resolution video group outputs) are
composite video outputs only. If the tied input is S-video, the switcher
encodes it to composite. If the tied input is composite video, the switcher
passes it through unprocessed.
•
Outputs 9 and 10
(the third and fourth low resolution video group video
outputs) are S-video outputs only. If the tied input is S-video, the switcher
passes it through unprocessed. If the tied input is composite video, the
switcher decodes it to S-video.
•
Outputs 11 and 12
(the fi fth and sixth low resolution video group video
outputs) are pass-through outputs only; the output is the same format
(S-video or composite video) as the selected input.
Bandwidth —
•
Computer video group —
The switcher provides a minimum of 300 MHz
(-3 dB) video bandwidth, fully loaded.
•
Low resolution video group —
The switcher provides a minimum of
150 MHz (-3 dB) video bandwidth, fully loaded.
