Hi5-4K-Plus Mini-Converter v1.12 4 www.aja.com
Chapter 1 – Introduction
Overview
AJA’s Hi5-4K-Plus preserves your vision with pristine image fidelity and HFR
support up to 60p for 4K/UltraHD SDI to HDMI 2.0 conversion needs. The
Hi5-4K-Plus can also generate HDR metadata in accordance with HDMI v2.0a/CTA-
861.3 and includes HLG support.
Hi5-4K-Plus provides a simple monitoring connection from professional 4K
devices using Quad 3G-SDI, Quad 1.5G-SDI, or Dual 3G-SDI outputs to new
displays with HDMI 2.0 inputs, for cost-effective monitoring for 4:4:4/4:2:2 60p
professional workflows.
Default Operation
The Hi5-4K-Plus auto configures to the connected inputs (no dipswitch settings
required).
The auto-configure function identifies the connected inputs, and outputs the
default or user configured HDMI output for the given input.
AJA’s Mini-Config application is available for firmware updates and advanced
configuration.
NOTE: Signal conversion requires the presence of a valid SDI video signal on one of the
SDI IN BNC connectors.
For single SD or HD inputs, BNC input 1 is the default input. For dual-link 1.5Gb
HD inputs, and 4K dual-stream 3Gb SDI inputs, inputs 1 and 2 are default. Where
applicable, both level A and B 3Gb inputs are auto-detected and supported.

Hi5-4K-Plus Mini-Converter v1.12 5 www.aja.com
When connecting the Hi5-4K-Plus with multiple SDI inputs in the auto-configure
mode (default), as the user connects the first HD-SDI to input 1, the unit will
output that input as a full screen HD. As soon as the second input is connected,
the unit will know that the input is 4K/UHD and the display will change to show
the two connected quadrants in the upper left and upper right of the 4K output.
The remaining two quadrants will be displayed as they are connected.
It is possible to use two dual stream 3G inputs to make 3840 or 4K video. In this
case SDI1 and SDI2 are assumed to be the inputs: SDI1 linkA makes the top left
quadrant, SDI1 linkB makes the top right quadrant, SDI2 linkA makes the lower
left quadrant, and SDI2 linkB makes the lower right quadrant. To use this mode
change the Video Source Selection to ‘2 X SDI 4K’.
The Hi5-4K-Plus will output either 4Kx2160 or 3840x2160 if more than one HD
input is present and the monitor can support those resolutions. For 4K input the
Hi5-4K-Plus may provide a center cut 3840, or pass the 4096 to the output, but
there is no scaling between the two.
AJA Mini-Config Control
Advanced control will support channel selection and mapping for eight channels
of audio from either of two groups of eight channels on any of the four SDI inputs.
Configuration set via AJA Mini-Config is stored in the Hi5-4K-Plus unit through
subsequent power cycles.
Features
• Convert Quad-3G-SDI to HDMI 2.0b at up to 4K 60p (see "Specifications" on
page 22 for a complete list of supported inputs)
• Support for 4:4:4/4:2:2/4:2:0 HDMI 2.0b output
• HDR signaling metadata pass-through and optional override
• HDR support for HDR10 and HLG
• Embedded audio pass-through of E-AC-3 (Dolby Digital Plus) compressed
audio, including DD+ Atmos
• Configure via USB port and supplied Mini-Config software
• Uses 5-20VDC power (DWP-U-R1 universal power supply included)
• Five year warranty
NOTE: 3D is not supported in this converter.
NOTE: 720p 4:4:4 formats are not supported in this release.

Installation
Typically, Hi5-4K-Plus installation consists of the following steps:
1. Ensure the Hi5-4K-Plus is disconnected from power.
2. Connect video equipment to the converter BNCs and HDMI connector.
3. Apply power to the converter (AJA power supply included).
4. The Hi5-4K-Plus 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 Hi5-4K-Plus via USB
• Make your changes using AJA Mini-Config setup screens.
This process is detailed in "USB Control and Setup—Using AJA Mini-Config" on page
8.
NOTE: The Hi5-4K-Plus 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 Hi5-4K-Plus 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

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.
