Chapter 1 – Introduction
Overview
The AJA HD10MD4 is a miniature digital downconverter for converting HD-SDI
video to standard definition SDI and analog component or composite video. The
HD10MD4 uses a full 10-bit data path and multi-point interpolation to produce
excellent quality down-converted video. In addition, the HD10MD4 converts
23.98 to a 59.94 Hz output video using the standard 3:2 pulldown technique.
The output can be formatted for either 4:3 or 16:9 standard definition monitors.
For 4:3 monitors, the output can be formatted for either the Letterbox or Crop
modes. The HD10MD4 can also receive SD video and output a different aspect
ratio. The HD10MD4 simultaneously passes video to both the SDI and analog
outputs. Eight channels of embedded audio channel can also be passed to the
SDI output.
Features
NOTE: The HD10MD4 automatically switches to PAL anytime the input is 1080i 50,

User Controls
The direct user interface for the HD10MD4 is an eight position DIP switch
accessible through a cut-out in the bottom of the unit. The exact function of the
DIP switches are described in "DIP Switches" on page 7.
The HD10MD4 also supports Mini-Config application control over its USB port to
a connected PC or Mac.

Installation
Typically, installation consists of the following:
Direct Control
1. Disconnect DC power from the converter.
2. Congure the DIP switches for the desired equipment conguration and
video formats.
3. Connect video equipment to the converter BNCs.
4. Apply power to the converter.
Mini-Config Control
1. Disconnect DC power from the converter.
2. Connect video equipment to the converter BNCs.
3. Apply power to the converter.
4. The converter will now run using the default factory settings. If you wish to
alter the factory settings, you’ll need to:
• Set DIP switch 1 ON (right) to permit remote Mini-Cong control.
• Install the AJA Mini-Cong software on your computer
• Attach the converter via USB
• Make your changes using Mini-Cong setup screens.
• This process is detailed in "Chapter 2 Operation" on page 7.

Chapter 2 – Operation
Default Operational Settings
The HD10MD4 Mini-Converter ships from the factory with the following
configuration (all DIP switches Off - Left):
• Local (DIP switch) control
• Component video
• YPbPr format
• Pedestal O
• Crop O
• Monitor 4:3
• Focus O
• Graticule O
If these settings apply to your requirements, you can simply connect the video
input and output signal cables and power up the unit.
For other applications, you can configure the unit using its DIP switch settings, or
by using the Mini-Config application and a PC or Mac via USB.
DIP Switches
DIP switches on the bottom of the unit are used to configure it without a
computer. The Left position is Off, the right position is On.

USB Control and Setup—Using AJA Mini-Config
Your AJA Mini-Converter can be used right out of the box for some applications
since it is designed to recognize inputs and perform standard actions
automatically by default. However, to use its full capability, you must use AJA’s
Mini-Config software application for PCs and Macs. This same application can be
used to update to new Mini-Converter software released by AJA.
NOTE: DIP switch 1 must be ON (Remote, Right) to permit Mini-Config control of the unit.
