Chapter 1 – Introduction
Overview
Features
12GM is a compact SDI transport converter that can solve a wide range of
UltraHD/4K equipment inter-connection problems. The product will convert
quad-link SDI signals to single-link SDI (Mux function) as well as single-link SDI to
quad-link SDI (Demux function).
12GM also supports Two Sample Interleave (2SI) to Square Division (Quadrant)
and Square Division (Quadrant) to Two Sample Interleave (2SI) pixel mapping.
The 12GM is configured using the free AJA Mini-Config application, which also
provides detailed input and output signal diagnostic information.

NOTE: The LEDs adjacent to each SDI input connector indicate by color the detected
signal type. Off is no signal, Green is SD-SDI, Red is HD-SDI, Amber is 3G-SDI,
Purple is 6G-SDI, and Blue is 12G-SDI.
Installation
Typically, 12GM installation consists of the following steps:
1. Ensure the 12GM is disconnected from power.
12GM Mini-Converter v1.4 5 www.aja.com
2. Connect video equipment to the converter BNC connectors.
3. Apply power to the converter (AJA power supply included).
4. The 12GM will now run using the default factory settings. If you wish to alter
the factory settings, you’ll need to:
• Install the AJA Mini-Cong software on your computer
• Attach the 12GM via USB
• Make your changes using AJA Mini-Cong setup screens.
This process is detailed in "USB Control and Setup—Using AJA Mini-Config" on page
7.
NOTE: The 12GM packs an unprecedented feature set into a mini converter box. As a
result, the unit uses approximately 12 watts of power. It will be very warm to
the touch, which is normal. The unit is engineered to operate across the full
temperature range, from 0 to 40 degrees C.
NOTE: For highest reliability, the mini converter relies on convection cooling instead
of using a built-in fan. Therefore, when installing the unit, mount in a location
where it has access to air for proper cooling. Do not stack the 12GM with other
mini converters.

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 AJA Mini-Config
AJA’s Mini-Config application is available for download from the AJA website.
To download the latest AJA Mini-Config package, which includes the AJA MiniConfig application, Mini-Converter firmware, and documentation, go to:
https://www.aja.com/en/products/mini-converters/mini-cong-software
Select either the Windows or Mac icon to download the desired version.
Mini-Converter Documentation
Included with the AJA Mini-Config package is a complete set of documentation
for all Mini-Converters supported by AJA Mini-Config. A .PDF of the Installation
and Operation Guide for the currently connected Mini-Converter can be accessed
from the AJA Mini-Config UI via the Help/Manual drop-down menu.
Documentation for all AJA Mini-Converters that use AJA Mini-Config can also
be accessed directly in the AJA Mini-Config download package Documentation
folder, and via the Documentation icon available on the Mac installer.
Documentation (and firmware) included with the AJA 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 webpage of that Mini-Converter.
Installing AJA Mini-Config
PC Installation
To install AJA Mini-Config on a Windows PC:
1. Download the application from the AJA website (select the Windows icon
on the AJA Mini-Cong Support webpage).
2. Open the AJA_MiniCong.zip le
3. Double-click on the MiniInstaller.msi le.
4. A Setup Wizard will guide you through the installation.
12GM Mini-Converter v1.4 7 www.aja.com
Figure 3. AJA Mini-Config PC Setup Wizard
5. Click Next to begin. Answer the questions in the subsequent dialogues.
When nished, an AJA Mini-Cong shortcut will be installed on the desktop,
and you will be able to locate the AJA Mini-Cong application in the AJA
folder in the Programs listing.
NOTE: If the AJA Mini-Config application already exists on the PC, a different Setup
Wizard appears.
Figure 4. AJA Mini-Config Setup Wizard, Reinstallation
With this screen you can Repair (reinstall) or Remove (uninstall) AJA Mini-Config
on the PC.
Mac Installation
To install the application on a Mac:
NOTE: Macintosh computers must be Intel-based (G5, G4 and earlier models will not
work with AJA Mini-Config).
1. Download the application from the AJA website (select the Apple icon on
the AJA Mini-Cong Support webpage).
2. Open the AJA_MiniCong folder.
3. Double-click on the AJAMiniCong.dmg le.
12GM Mini-Converter v1.4 8 www.aja.com
4. Answer the prompt and a utility program will be launched.
Figure 5. AJA Mini-Config Mac Installer
5. To complete the installation drag the “MiniCong.app” icon to the
Applications folder.
Running AJA 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 AJA 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 MiniConfig application located inside the AJA Mini-Config folder.
Mac Startup
To run AJA 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 AJA Mini-Config application bar allows you to
save the current state of the Mini-Converter to a preset file for later recall.
12GM Mini-Converter v1.4 9 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 AJA Mini-Config
The AJA 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 MiniConverter 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.

NOTE: The LEDs adjacent to each SDI input connector indicate by color the detected
signal type. Off is no signal, Green is SD-SDI, Red is HD-SDI, Amber is 3G-SDI,
Purple is 6G-SDI, and Blue is 12G-SDI.
Selecting a Mini-Converter with the pulldown menu causes this application to
connect to the selected converter. The graphic of Mini-Converter and text below
it provides:
• Type of converter
• Firmware version
• Serial number of the unit.
A status field at the bottom of the screen shows if your application is connected
and communicating with the Mini-Converter.
When configuring the Mini-Converter, select it from the top pulldown, view the
current settings and change any values. Making a change communicates that
new value to the Mini-Converter’s non-volatile memory.
The Tabs delineate control screens with groups of controls for each type of task to
be performed. The controls for the actual configuration parameters are specific
to each Mini-Converter type. When you Click on any of the tab buttons, the pane
below the tabs will change to match your tab selection. Any changes you make
are immediately applied and will be saved, overwriting previous settings.
