Chapter 1 – Introduction
Overview
The HA5-Plus converts HDMI to 3G, HD, or SD SDI. Up to eight channels of HDMI
audio are embedded into the SDI output allowing a convenient single cable
audio/video connection. Two external analog audio inputs can replace two of
these embedded audio channels, if desired. The HA5-Plus supports long HDMI
cables on the input. The HA5-Plus is useful for connecting HDMI cameras and
other sources to SDI capture cards and equipment.

supported inputs).

• Convert between integer and non-integer frame rates using frame drop/
repeat
• EDID Emulation
• Full HDMI support including embedded audio
• Equalized HDMI input supports long HDMI cables up to 30m
• PLL clock filtering for low jitter SDI outputs
• Lock LED shows type of input source: SD (green), HD (red), or 3G (amber)

Audio
The HA5-Plus converter supports 8 audio channels (4 stereo pairs) at 24-bit/48
kHz which it dis-embeds from HDMI and embeds into SDI. For proper embedding,
audio must be synchronous to video. If audio is not synchronous with video or
the sample rate is not 48 kHz, then Mini-Config must be used to set the Sample
Rate Converter to convert audio to 24-bit/48 kHz and then synchronize it with
input video before embedding.

User Controls
Mini-Config Control
Auto controls configures the unit automatically to match the input and output
video parameters. Advanced Mini-Config control supports setting the RGB video
range, and adjusting audio input, conversion, and routing to embedded HDMI
audio.
Configuration set via Mini-Config is stored in the HA5-Plus unit through
subsequent power cycles.
Installation
Typically, HA5-Plus installation consists of the following steps:
1. Ensure the converter is disconnected from power.
2. Connect equipment to the converter HDMI input connector, the output
BNC connector, and the analog audio inputs (if used).
3. Connect audio equipment to RCA connectors (optional)
4. Apply power to the converter (AJA power supply included).
5. The converter will now run using the default factory settings. If you wish to
alter the factory settings, you’ll need to:
• Install the AJA Mini-Config software on your computer
• Attach the converter via USB
• Make your changes using Mini-Config setup screens.
• This process is detailed in "Chapter 2 Operation" on page 7.

Chapter 2 – Operation
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.
Acquiring Mini-Config
AJA’s Mini-Config application is available for download from the AJA website.
To download the latest Mini-Config package, which includes the Mini-Config
application, Mini-Converter firmware, and documentation, go to:
https://www.aja.com/en/products/mini-converters/mini-config-software
Select either the Windows or Mac icon to download the desired version.
Mini-Converter Documentation
Included with the Mini-Config package is a complete set of documentation for
all Mini-Converters supported by Mini-Config. A .PDF of the Installation and
Operation Guide for the currently connected Mini-Converter can be accessed from
the Mini-Config UI via the Help/Manual drop-down menu.
Documentation for all AJA Mini-Converters that use Mini-Config can also be
accessed directly in the Mini-Config download package Documentation folder,
and via the Documentation icon available on the Mac installer.
Documentation (and firmware) included with the Mini-Config application are the
versions available at the time of distribution. However, Mini-Converter software,
firmware and documentation are updated regularly, so newer versions may exist.
To download the latest documentation for an individual Mini-Converter, go to:
https://www.aja.com/en/category/mini-converters
and navigate to the Support web page of that Mini-Converter.
Installing Mini-Config

in the Programs listing.
NOTE: If the Mini-Config application already exists on the PC, a different Setup Wizard
appears.

will not work with Mini-Config).
1. Download the application from the AJA website (select the Apple icon on
the Mini-Config Support web page).
2. Open the AJA_MiniCong folder.

Figure 5. Mini-Config Mac Installer
5. To complete the installation drag the MiniCong.app icon to the
Applications folder.
Running Mini-Config
Connect the Mini-Converter to the PC or Mac via the supplied USB cable. Connect
the external power supply (supplied) to the Mini-Converter.
PC Startup
To run Mini-Config on a PC, double-click on the AJA Mini-Config icon on your
desktop, or open the AJA folder in the program list and click on the AJA Mini-
Config application located inside the Mini-Config folder.
Mac Startup
To run Mini-Config on a Mac, open the Applications folder and locate the AJA
Mini-Config application. Double-click the application to launch it.
Saving Setups
A File drop down menu on the Mini-Config application bar allows you to save the
current state of the Mini-Converter to a preset file for later recall.

HA5-Plus Mini-Converter v1.8 10 www.aja.com
Using this feature you can set up the converter for different applications, storing
each configuration (Save Preset As...) with a unique name for easy recall (Open
Preset...).
A Revert to Factory Settings menu item similarly allows you to change the
settings back to AJA’s factory defaults.
Operating Mini-Config
The Mini-Config application provides a graphic interface for viewing settings
and updating software. It consists of an information area at the top that shows
the available Mini-Converters attached to the computer via USB, with a graphical
rendering of the selected Mini-Converter showing all the connectors and their
current state.
Colored text next to the connectors indicates the signal type and what the Mini-
Converter is doing:
• Blue text indicates the values automatically selected
• Black text indicates values that you have manually selected
• Red text indicates the Mini-Converter is not detecting a signal, or cannot
operate with the current user settings.
NOTE: Even if no output device is detected, the SDI connector text still shows the signal it
is outputting.
NOTE: Configuration settings in red will change based on the attached output device as
well as input signals. For improved accuracy and reliability, you should configure
the Mini-Converter only when the target output device is attached and input
signals are supplied at the inputs.
Screens are virtually the same on both PC and Mac, with subtle differences that
reflect the general look of the platform environment.
