1. Introduction

1.1 General

Thank you for purchasing the Black Box Model AC139A, a powerful
video processor and scaling product. It combines the functions of many
products in one compact and versatile unit. It has both high definition
analog as well as digital inputs. Two outputs are available
(simultaneously active†), one analog (RGBHV) and one digital DVI-D
(HDMI™ compatible).

Figure 1 – Block Diagram

The user can select the desired input using individual buttons on the front
panel, on the included IR-remote, or by issuing ASCII RS232 commands.

The output resolution can be set can range between 480i to 1080p for
HDTV, or VGA (640x480) to WUXGA (1920X1200) for the PC. The
unit uses the latest high-resolution video scaling techniques to produce a
superior video output for a crisp image on the output display. Both video
outputs can also be mirrored horizontally making it ideal for
teleprompting and rear projection systems where the image needs to be
.flipped.

The desired output resolution is set directly using individual buttons on
the IR remote, or via unique ASCII RS232 commands. The front panel
can also be used to set the output resolution. A user-friendly on-screen­display (OSD) is used to control the operation of the device from the
front panel. There are also ‘hot-key’ combinations on the front panel to
directly set the output to basic PC or HDTV resolutions so that a picture
can be displayed on any LCD.

†

For HDMI™ compliance, when the DVI input is selected, and HCDP content protection is
detected on the signal, the HD15 analog output is blanked. The front panel input LED will
blink when this condition is detected. The Digital DVI output will be active when connected to
a HDCP compliant LCD (such as a display with HDMI™ input).

The DVI input is HDCP compliant. This allows the unit to be used as an
HDMI™ Video Scaler (HDMI™ audio is not passed through). When the
digital input has HDCP encryption, the DVI output must be connected to
a HDCP compatible LCD (by definition all displays with HDMI™ input
must be HDCP compliant).

Built-in universal power supply keeps the installations clutter free.

2. Installation

2.1 Connecting the Video Inputs and Outputs

The video scaler can accept a VGA (analog RGBHV from PC), DVI
(digital video from PC or HDMI™ source), and Component Video (Y Pb
Pr) from any source.

When the source is from an HDMI™ output, an HDMI to DVI cable or
adapter is required. Please contact Black Box if you need to purchase this
cable.

Two outputs connectors are provided. Both show the selected input at the
desired output resolution.

Video cables for connecting the I/O ports are not supplied with the unit.

If you would like to mount the unit in a rack, please contact Black Box to
purchase a rack-mount accessory kit for the unit.
