Features
EDID Minder — The Extron EDID Minder ensures the resolution of the video source signals
is compatible with the display devices.
Sync processing — Using regular sync processing to allow centering control (H-shift or
V-shift) can create problems with some digital display devices as a result of the sync delay.
The Extron ADSP option maintains a stable sync signal while allowing centering control.
Digital Display Sync Processing (DDSP
™
) — This feature ensure proper displays without
altering sync pulse timing or width. The sync processing type is selected via a rear panel DIP
switch.
Digital Sync Validation Processing (DVSP) — In critical environments or unmanned,
remote locations, it is vital to know which sources are active. The exclusive Extron DSVP
confirms that input sources are active by scanning all sync inputs for active signals. DSVP
provides instantaneous frequency feedback for composite sync or separate horizontal and
vertical sync signals via the Remote port of the interface.
Automatic sync stripping — Sync signals are automatically stripped from the red, green,
and blue video input signals. The interfaces normally output sync simultaneously as separate
horizontal and vertical sync and as composite sync, but sync on green (SOG) can be selected
via a rear panel DIP switch.
Sync polarity adjustment — Horizontal and vertical sync output can either follow input
sync polarity, or outgoing sync can be forced to positive or negative via an internal jumper.
Serration pulse selection — This DIP switch selectable feature adds or strips the serration
pulses from the output signal to make it compatible with digital display devices.
LCD scan rate indicator — This backlit liquid crystal display (LCD) indicates the horizontal
and vertical sync rates, and the minimum and maximum centering limits. A DIP switch is
provided for turning off the backlight.
Vertical sync pulse width adjustment — Vertical sync pulse width can be adjusted via a
rear panel DIP switch.
RGBHV, RGBS, or RGsB outputs — Select the output format via cabling setup and rear
panel DIP switch.
Stereo audio — The interface processes unbalanced PC stereo audio inputs as a line level,
balanced stereo or mono audio output.
Horizontal and vertical centering controls — Separate front panel controls allow
separate horizontal and vertical centering adjustments.
Level (boost) and peaking controls — Separate front panel controls compensate for
signal losses from long cable runs.
Thirty memory presets — Thirty spaces are reserved in the memory of the interface for
storing user-defined combinations of horizontal and vertical position settings based upon
input signal scan rates. The interface automatically recalls the position settings when it
detects an input signal with a matching scan rate.
Remote control input selection — Connect a remote contact closure keypad, an RS-232
control system, or a computer to the rear panel Remote port to remotely control the
interface.
Front panel security lockout (Executive mode) — Locks out front panel control of
horizontal and vertical shift and input selection.
