Chapter 2: Overview
2. Overview
2.1 Introduction
The Multi-Input Digital Scaler with Audio is a multiple format switching video
scaler. It has five different types of video inputs and a scaled digital output that
can be switched to any of the inputs. The scaler accepts various input formats and
resolutions and scales to a specific output format and resolution.
Inputs include: HDMI (up to 1080i/p), PC (from VGA [640 x 480] to WUXGA
[1920 x 1200]), Component Video (SD and HD from 480p to 1080i/p), S-Video
(NTSC or PAL), and Composite Video (NTSC or PAL).
You can specify the output format and resolution as either PC (VGA [640 x 480]
to WUXGA [1920 x 1200]) or Component Video (YPbPr from 480i/p to 1080i/p).
You can control the scaler in many ways, including front-panel lighted push
buttons (with on-screen display menus), using the included IR remote control, or
via an RS-232 serial interface. The controls include input switching, setting the
output resolution, picture adjustment (color, brightness, contrast, and sharpness),
aspect ratio (standard, 16:9, or 4:3), digital noise reduction, 3-D comb filter On/
Off, and many other advanced features.
Use the scaler in boardrooms, classrooms, digital signage, and high-end home
theater applications. You can set its output for any LCD projector, PC LCD
monitor, plasma, or HDTV displays.

4.5 Front-Panel Lockout
Under certain circumstances you might want to disable the front-panel controls
(for example, to prevent unauthorized or accidental changes to the settings while
the unit is in use). To disable the front-panel controls you must use the RS-232
port (see Chapter 5 for details).
You can remove the lockout from the front panel by performing a full factory
default reset operation!
To reset to the factory default settings, press the RESET button on the IR remote
control for 5-10 seconds. The scaler will turn on when you press the reset button
and turn back off when the software reset has completed.
